Almost all satellites are powered by solar cells – but solar cells are heavy. While conventional high-performance cells reach up to three watts of electricity per gram, perovskite and organic hybrid cells could provide up to ten times that amount. A research team from the Technical University of Munich (TUM) and the German Aerospace Center (DLR) has now tested this type of cell in space for the first time.Perovskite and organic solar cells are promising options for future generations of solar cells. Over recent years, their efficiency has rapidly caught up with that of conventional silicon-based cells.“The best perovskite solar cells currently achieve efficiency levels of 25 percent,” says Peter Müller-Buschbaum, Professor of Functional Materials at the TUM Department of Physics. “These thin solar cells, less than one micrometer thick, applied to ultra-thin, flexible synthetic sheet, are extremely lightweight. They can therefore produce nearly 30 watts per gram.”
Manufacture at room temperature
This is only possible thanks to a decisive advantage of the new solar cells: Production of silicon solar cells requires very high temperatures and elaborate processes. Perovskite cells and organic semiconductors, on the other hand, can be manufactured at room temperature from solution.
“These organic solutions are very easy to process,” explains the lead author Lennart Reb. “Thus the technologies open up new fields of application in which conventional solar cells were simply too unwieldy or too heavy – and that also applies far beyond the aerospace sector.”
Test flight into space
Two different types of organic and perovskite solar cells were tested in space for the first time on a research flight as part of the MAPHEUS 8 program at the European Space and Sounding Rocket Range in Kiruna, Sweden. The rocket reached a height of nearly 240 kilometers.
“Our MAPHEUS program allows us rapidly to implement experiments in a zero-gravity environment, offering exciting research findings,” says Professor Andreas Meyer, co-author and Head of the DLR Institute of Materials Physics in Space. “This time it went particularly quick: it took us less than a year to progress from the initial idea to the maiden flight of the solar cells as part of the MAPHEUS 8 program.”
Power generation under exeptional conditions
“Electrical measurements during the flight and the evaluation after recovery of the rocket showed that perovskite and organic solar cells can achieve their potential in terms of expected performance in orbit height,” reports Professor Müller-Buschbaum. “Our measurements are therefore of great scientific value.”
The solar cells also generated electrical energy under diffuse incidence of light. “Cells turned away from the sunlight, which received only sparse lighting exclusively from the earth during the flight, still supplied electricity,” says Reb.
Due to their much thinner thickness, the new solar cells could therefore also be used in much dimmer light, for example on missions to the outer solar system on which the sun is too weak for conventional space solar cells.
According to DLR material scientist Andreas Meyer, “it would not be the first time that innovations are first established as space technologies but go on to be used around the world in other sectors. One reason for this is probably the very strict requirements that space places on all technical components.”

A newly proposed inverter design relies on a solar charge controller featuring maximum power point tracking. It is based on an artificial fish-swarm algorithm, which offers high convergence speeds, flexibility, fault tolerance, and accuracy.
Researchers from the University of Science and Technology of China have designed a novel topology for a bidirectional inverter for uninterruptible power supply (UPS).
The proposed inverter design, with battery backup, relies on a maximum power point tracking (MPPT)solar charge controller based on an artificial fish-swarm algorithm, which is inspired by the collective movement of fish and their instinctive behaviors. This algorithm is said to offer high convergence speeds, flexibility, fault tolerance, and accuracy. The scientists said the perturb and observe (P&O) algorithm, which is most commonly used for PV applications, has a number of drawbacks.
The newly developed algorithm works according to a two-step process. The first step involves a variable perturbation observation method to find the maximum power point of the system. In the second step, the proposed device makes use of the fish-swarm algorithm to rapid-search and track the global maximum power point.
The PSpice software was used for the model simulation, which was aimed at obtaining the volt-ampere characteristic curve of PV system output. “The solar array simulator was used to verify the effect of maximum power point tracking at different light intensities,” the researchers said.
The open circuit voltage of the simulator was 193.785 volts, while the short circuit current was 2.6786 ampere. The ambient temperature was 27 C and the lighting power density was 1,000 W/m2. The simulation showed that the MPPT tracking has an average efficiency of 99.5% and a maximum efficiency of 99.9%.
“According to the curves of the output power, voltage and current of the solar panel in 60 seconds and the Boost circuit can track the maximum power point around 10 seconds,” the researchers said.
The inverter is suitable for uninterrupted power supply in case of grid failure. “The distortion rate of the grid-connected current waveform was within 2% and the DC current component was less than 0.5%,” the scientists said. “The full bridge inverter can be reverse rectified by connecting the reverse diode in parallel with the full-bridge switch. It provides the possibility for the power generation to charge the battery.”
They presented the new inverter topology in “Bidirectional energy storage photovoltaic grid‐connected inverter application system,” which was recently published in the International Journal of Energy Research.

Group spinoff Maxeon Solar Technologies will commercialize the Performance 5 line in the fourth quarter. The high-efficiency, bifacial mono-PERC solar panels will be made with large format eight-inch G12 wafers and will have an efficiency of 21.2%.
“Our release of the new SunPower Performance 5 panels comes along with a renewed commitment to large-scale installations supported by significant manufacturing capacity scale-up of shingled cell panel technology by our Huansheng Photovoltaic (HSPV) joint venture in China,” SunPower said.
Maxeon Solar Technologies is also owned by Tianjin Zhonghuan Semiconductor, which was recently acquired by TCL , one of China’s biggest electronics manufacturers. SunPower’ss HSPV joint venture with Zhonghuan will increase production capacity at its three factories in China from around 2 GW to 8 GW by 2021. The first of the three manufacturing facilities will be fully ramped up by the end of this year.
SunPower announced plans to spin off its manufacturing business into a new company last November. It also recently decided to sell its solar O&M business to Canadian mid-market private equity firm Clairvest Group for an undisclosed sum.

Duke Energy Florida will add 30 MW of energy storage to its portfolio with three separate installations.
The battery sites will be located at Duke Energy’s Lake Placid Solar Power Plant in Highlands County, John Hopkins Middle School in Pinellas County, and southwest of Gainesville in Alachua County. The sites will play an important role in supporting public safety during significant weather events, as well as addressing overall electric grid efficiency and reliability.
“Batteries are an exciting technology that allows us to bring more renewables onto the grid and support resiliency in our communities,” said Catherine Stempien, Duke Energy Florida state president. “These projects help us determine the best uses so that when battery storage technology becomes even more cost-competitive, as it is projected to do, we can deploy them quickly for the benefit of our customers.”
The versatility of battery storage technology allows Duke Energy, as the grid manager and operator, to maximize benefits to customers and the grid.
- An 18-MW lithium battery site will be built at the company’s 45-MW Lake Placid Solar Power Plant, which came online in December 2019. The addition of energy storage to the utility-scale solar plant will be the first of its kind for Duke Energy Florida. It will allow solar energy to be dispatchable for Duke Energy Florida grid operators and improve overall plant efficiency.
- An 8.25-MW Micanopy lithium battery site will be located 15 miles southwest of Gainesville in Alachua County. The battery storage site provides a cost-effective solution for focused power quality and reliability for the town of Micanopy and nearby neighbors.
- A solar + storage microgrid site will be added at Pinellas County’s John Hopkins Middle School. The microgrid will support grid operations and provide backup electric power to the school when it must operate as a special need’s hurricane evacuation shelter. The microgrid consists of a 1-MW solar parking canopy array and a 2.5-MW battery and controls, which will store and deploy clean, renewable energy to the school and grid. The project enhances electric service and grid operations for customers.
“Duke Energy’s new battery energy storage project will provide students at John Hopkins Middle School with a real-life lesson about solar energy and the need to protect our environment by seeking alternative methods of generating electricity,” said Clint Herbic, associate superintendent of operational services for Pinellas County Schools. “It also will be a critical addition for our county’s residents, as the school also serves as a Special Needs Hurricane Shelter.”
The battery sites will serve customer electric needs, increase energy security and complement other electric resources on the grid. All three sites are on track to be completed by the end of 2021. Along with three other battery installations announced last year in Gulf, Columbia and Gilchrist counties, these sites will fulfill Duke Energy Florida’s pledge to customers to add 50 MW of energy storage by 2022.

New solar panels advancements are set to change the worldwide solar powered vitality scene. A portion of these promising innovations are now in the propelled phases of advancement, and could hit the market reasonably soon. With these developments, land required for solar installation will be reduced drastically or unattractive rooftop spaces. (Stylishly engaging and profoundly proficient sun based shingles, for instance, are as of now making alluring sun oriented rooftops.)
What are transparent solar panels?
Photovoltaic glass is probably the most cutting-edge new solar panel technology that promises to be a game-changer in expanding the scope of solar. These are transparent solar panels that can literally generate electricity from windows—in offices, homes, car’s sunroof, or even smartphones. Blinds are another part of a building’s window that can generate electricity (we will discuss it in a later section).
Researchers at Michigan State University (MSU) originally created the first fully transparent solar concentrator in 2014. This clear solar panel could turn virtually any glass sheet or window into a PV cell. By 2020, the researchers in the U.S. and Europe have already achieved full transparency for the solar glass.
These transparent solar panels can be easily deployed in a variety of settings, ranging from skyscrapers with large windows to a mobile device such as a phone, a laptop, or an e-reader. As these solar power windows can simply replace the traditional glass windows in offices and homes, the technology holds the potential to virtually turn every building in the United States and the world into a solar producer.
How do solar panel windows work?
A transparent solar panel is essentially a counterintuitive idea because solar cells must absorb sunlight (photons) and convert them into power (electrons). When a solar glass is transparent, the sunlight will pass through the medium and defeat the purpose of utilizing sunlight. However, this new solar panel technology is changing the way solar cells absorb light.
The cell selectively harnesses a portion of the solar spectrum that is invisible to the naked eye, while allowing the normal visible light to pass through. To achieve this technological wonder, the researchers have developed the transparent luminescent solar concentrator (TLSC) rather than trying to do the impossible by creating a transparent photovoltaic glass cell.
The TLSC is composed of organic salts that are designed to absorb specific invisible UV and infrared light wavelengths, which then glow (luminesce) as another invisible wavelength. This new wavelength is then guided to the edge of the window plastic, which thin PV solar cell strips convert it into electricity.
Once the mass production begins for transparent solar panels, researchers estimate that the TLSC should be able to deliver an efficiency of about 10%. This may not appear to be an earth-shattering number, but on a national or global scale, when almost every window in a home or office building consists of clear solar panels, the results can be trans-formative.
As the transparent solar panels cost comes down with their mass production and deployment, this non-intrusive technology can be scaled right from commercial and industrial applications to handheld consumer devices, while remaining very affordable.
Types of transparent solar panels
Just the way solar roof panels are currently produced using different technologies (Tesla’s solar shingles and other technologies), solar windows are also being developed using different techniques. The two major types of transparent solar panels include partial and full transparent panels.
Partially transparent solar panels
A German manufacturer, Heliatek Gmb, has developed this partially clear solar panel, which can absorb about 60 percent of the sunlight it receives. Compared to the conventional solar PV cells, the partially transparent solar panels have a lower efficiency at 7.2%. However, solar power generation can be increased by adjusting the balance between the sunlight that is transmitted and absorbed.
For instance, in south-facing glass buildings, it is often important to reduce the transmitted light (many such office buildings already use tinted glass). In these locations, the partially transparent solar panel can work very well.
Fully transparent solar panels
As described in the beginning of this report, researchers at MSU have already achieved a breakthrough to produce fully transparent photovoltaic glass panels that resemble regular glass. Researchers estimate the efficiency of these fully transparent solar panels to be as high as 10% once their commercial production commences.
It’s vital to understand here that when it comes to solar panel windows, efficiency of the panel is not the be all and end all. In practical terms, a less efficient solar window only means that the window has to be larger in size compared to the more efficient panel in order to generate the same amount of electricity.
Once fully transparent solar panels get integrated into large windows in buildings, their lower efficiency is bound to be overcompensated by their potential scale of deployment.
Solar panel blinds: An easy-to-implement solar window technology
Solar panel blinds are a supplement to transparent solar glass/panels when using the window to generate electricity. Solar power panels are designed to harvest sunlight to produce energy, while the essential function of window blinds is to block direct sun’s rays from entering inside.
Solar panel blinds are cleverly combining these two divergent functions. An innovative startup called SolarGaps has introduced solar panel blinds, which it claims can cut down energy costs by up to 70 percent. For every 10 sq. ft. of window space, these solar window blinds can generate 100 watts of power (you could roughly power three laptops with this much electricity).
These solar blinds can be installed either inside or outside, and you can control their angle and positioning using an app that will also inform you of the energy generation figures. It includes a setting to automatically optimize the angle of the blinds according to the position of the sun.
Pioneers in transparent solar panel research and manufacturing
Researchers at Michigan State University and MIT as well as manufacturers such as Ubiquitous Energy, Physee, and Brite Solar are pioneers in promoting this new solar panel technology.
Ubiquitous Energy, in partnership with a leading glass manufacturer NSG Group, is developing Ubiquitous’s unique ClearView Power technology to integrate transparent solar panels into architectural glass windows. ClearView Power’s transparent solar coating can be directly applied to building windows at the time of the normal glass making process.
The technology also enhances energy efficiency of the buildings through blocking of infrared solar heat. When combined with solar energy generation through clear solar panels, it can lead to net-zero energy buildings. The company has already announced that ClearView Power’s transparent solar cells have reached an electricity conversion efficiency of 9.8%.
Physee is a European manufacturer that has introduced an advanced product called PowerWindow. In fact, it is the only currently installed transparent solar panel in the world right now (covering 300 sq. ft. in a Dutch bank building).
Physee’s PowerWindow makes use of small solar panels that are installed along the window pane edges to generate power. While these solar windows are unable to be a standalone power source for buildings yet, the company is confident of rapid improvements in the scale and efficiency of its transparent panels.
PowerWindows serve as the building blocks for “SmartSkin,” the clear photovoltaic glass that the company is promoting as the “future-proof glass façade for next-generation sustainable buildings.” SmartSkin can work autonomously to sense, power, and regulate the climate inside the building using intelligent systems.
The future of transparent solar technology
The potential to generate renewable, clean energy from the sun is enormous with transparent solar panels, considering the number of skyscrapers and buildings already in existence or under construction with a massive amount of glass surface .
According to Richard Lunt, the Johansen Crosby Endowed Associate Professor of Chemical Engineering and Materials Science at MSU, highly transparent solar cells represent the “wave of the future” for new solar panel technologies.
Lunt says that these clear solar panels have a similar power-generation potential as rooftop solar, along with additional applications to improve the efficiency of buildings, cars and mobile devices. Lunt and his team estimate that the U.S. alone has about 5 to 7 billion square meters of glass surface at present. (Just in the last 10 years, as much as 682 million sq. ft. of office space has been added in the U.S.).
With this much of glass surface to cover, transparent solar panel technology has the potential to meet about 40 percent of the country’s annual energy demand. This potential is nearly the same as that of rooftop solar. When both these technologies are deployed complimentarily, it could help meet nearly 100 percent of the U.S. electricity needs if we also improve energy storage.

The Chairman, Senate Committee on Power, Senator Gabriel Suswam, has assured Nigerians that the problems associated with the quality of electricity supply in the country would soon be addressed with a legal framework.
He said the Senate was putting together a comprehensive Electricity Bill in collaboration with the Nigerian Electricity Regulatory Commission to tackle the challenges facing the consumers, the suppliers and the regulators.
Suswam stated this when he led the Senate Committee on Power on oversight function to NERC head office on Monday.
He said, “The legal framework that we have in place which regulates the power sector was set up in 2004, just to enable the government to privatise the sector.
“Now we’ve gone beyond privatisation and there has to be an Electricity Act for the country.
“The Act, which should be ready in August, will set a legal framework that would touch on the issue of energy theft and the sanctions against those who bypass meters.”
The senator said the electricity distribution companies operating in the country had acceded to the appeal by the National Assembly to suspend their planned tariff hike, which should have started in August.
He said, “The Act that established the Nigerian Electricity Regulatory Commission gave it the power to make sure it carries out tariff reviews.
“To a large extent, they have done that but we now find ourselves in a difficult economic situation at the moment.
“By their own programme, the distribution companies are supposed to activate tariff increase by the first of July this year but the National Assembly appealed to them to tarry a while so that Nigerians could recover from the economic shock before they can activate the tariff.”
The Chairman/Chief Executive Officer of the NERC, Prof. James Momoh, said the electricity sector in Nigeria required $2.1bn to provide additional infrastructure to boost supply, bring in investors and improve the quality of life.
He noted that the infrastructure in the sector had deteriorated with obsolete equipment capable of generating 13, 000 Megawatts installed power capacity.
Momoh lamented that only 5,000MW generated was available for distribution by the DISCOs.
Speaking to journalists on the sidelines of the visit, Momoh said the suspended tariff would not have affected the poor.
He said the regulator had mandated the distribution companies not to include those with low purchasing power in the tariff increase process.
The NERC boss stated that a mechanism was developed that would absorb poor Nigerians from the proposed tariff hike.

Maximize your battery life, avoid common mistakes and reduce costs by learning the way to select the proper battery for your system anytime.
Did you recognize that batteries, even with nearly identical specifications, may have unequal life and performance? It’s true. Choosing the proper model for your system can mean the difference between long project life, low maintenance and high performance — or frustrating downtime and early failure.
All batteries are made differently. Some manufacturers use heavier grids and more lead, robotic assembly and automatic internal control , and exhaustive performance testing. Other manufacturers make batteries using manual assembly and outdated materials which will compromise performance. Low-price batteries appear to be a bargain, but they often require more maintenance, fail earlier and price more within the end of the day.
By asking the proper questions, you’ll be will make you identify differences in design, materials, manufacturing and internal control to decide on the most effective battery for you.
Understand Different Battery Types
The first step is to chose the proper type. Lead-acid batteries are made for specific applications, and a few aren’t an honest fit renewable energy (RE) systems. Automotive and commercial starter batteries deliver short bursts of power and occupy full charge most of the time, making them unsuited for such applications. Uninterrupted Power Supply (UPS) batteries are designed to supply backup electricity during power outages but won’t tolerate continuous discharge and charge cycles.
Deep-cycle batteries deliver electricity for an extended time, even multiple days, because they’re designed for constant discharge and charge cycles. The difference between deep-cycle and RE-specific batteries is that RE batteries’ basic design accounts for the precise requirements of renewable energy applications.
Flooded batteries are the foremost commonly used batteries in RE and grid-backup systems, because they’re affordable, easy to take care of , long-lasting and reliable. Valve-regulated lead–acid (VRLA) batteries, like Absorbent Glass Mat (AGM) and GEL, are maintenance-free but typically costlier . Whatever sort of battery you select , know which materials, construction methods and internal control systems translate into affordable, reliable power for your system.
Materials And Manufacturing Matter
A battery produces electrical current through a reaction that converts its stored energy into electricity . This process starts within the lead itself. Most manufacturers within the North American battery industry use recycled lead, therefore the performance and lifespan differences between lead within the batteries come from the quantity of lead, additive formulation, lead-oxide production methods and quality control employed by producers.
Metal grids that hold lead paste make energy storage possible. Thicker, heavier plates withstand corrosion longer and hold more lead for chemical reactions, in order that they increase battery life. But raw lead prices have skyrocketed some years back, and since lead comprises 60 to 80% of a battery’s cost, there’s pressure to chop corners to offset staple price hikes.
Manufacturers that understand the importance of quality still produce a superior product. they are doing not attempt to cut costs through curtailing on key materials like lead, but by improving manufacturing efficiency and using of active lead materials. Ultimately, more lead and advanced manufacturing save customers money because they don’t need to replace their batteries as often.
Even grid production methods affect life. Some manufacturers use expanded metal and stamped grid production because they’re quicker, but these methods embed impurities and porosity into grid wires. In contrast, grids produced by gravity casting contain no impurities and near-zero porosity. Gravity-cast plates extend life and improve reliability.
Active lead material is applied to plates during a process called pasting, and dozens of variables in paste mixing significantly affect battery performance. In conventional systems, these variables are adjusted by hand and paste is just as good as its operator. Computerized paste mixing alleviates these problems by instantly adjusting variables.
Once grids are pasted, they’re cured (dried in specialized “curing ovens” at a specific temperature and humidity) to bond active lead materials to the grid for better performance and longer life. search for batteries built with plates prepared in curing ovens, which optimize important variables like temperature and humidity at every stage of the curing cycle to make sure all plates deliver optimal capacity and repair life.
After curing, battery plates are stacked in groups and connected by fusing the plates along side a lead strap that makes a shunt circuit between the plates. Many companies still use strap-assembly processes that originated within the half of the 20th century because they’re economical. Workers manually attach lead lugs to a strap and burn them together one-by-one employing a torch and lead stick or by manually pouring molten lead around a jig. Manually welded straps have weaker connection points.
Other companies use cast-on-strap (COS) assembly systems that fuse battery plates together simultaneously at the optimal temperature. Because COS allows for 4,000 adjustments versus only 40 for hand welding, it ensures consistent, low electrical-resistance welds that strengthen connections, resist cracking and improve battery life. Robotic COS assembly also prevent failure modes that are common with manually-assembled batteries, like “lead run-down” between plates, and permit for features that reduce corrosion, increase current and reduce maintenance costs.
Properly integrating the COS process may be expensive and time-consuming. ensure your battery manufacturer has had time to refine its COS system. If a corporation advertises using COS, ensure to ask if it produces 100% of its offerings using COS manufacturing.
Following assembly, batteries are charged for the first time in a very process called formation that converts lead sulfate and ensures maximum capacity. Some companies “speed up” formation using higher currents, which cut production time at the expense of active (usable) material and lifespan. In contrast, lower current over a extended time always leads to longer life.
Quality control should be built into all stages of production to enhance product quality and consistency. in advanced plants, this includes machine testing for brief circuits, along side computerized welding and warmth sealing. Some battery companies even use vision systems (image capturing and advanced software that automatically inspect parts) to identify defects humans can miss.
When you know what check for — and what to avoid — in a renewable energy battery, it’s much easier to search out the most effective model for your needs. to match manufacturing techniques and materials and obtain an improved idea of which batteries will perform better and last longer, visit your RE battery manufacturer’s website or call the manufacturer or your distributor.
