Swedish scientists reviewed wavelength-selective PV tech for agrivoltaics and recommended creating standards for reporting their performance.

Wavelength-selective PV tech for agrivoltaic applications

Researchers at the Mälardalen University in Sweden have provided an extensive review of all wavelength-selective PV systems for applications in agrivoltaics.

“Traditional opaque silicon panels often create excessive shading that limits light availability for most shade-intolerant crops. Yet, plants do not need the full spectrum of sunlight for growth but only the region where they are photosynthetically active. In some cases, a full spectrum may even hinder their development,” the research’s lead author, Silvia Ma Lu, told pv magazine. “This opens the door for wavelength-selective solar photovoltaic (WSPV) technologies. WSPV systems are designed to transmit light at the wavelengths most beneficial for photosynthesis, while reflecting or absorbing less essential wavelengths to generate electricity.”

A much-needed solar cell factory is coming to the US

Canadian solar panel maker Heliene and India’s solar cell maker Premier Energies are joining forces to build a US solar cell factory.

This is great news for the US, as there is currently a shortage of US solar cell manufacturing capacity.

Chiranjeev Saluja, managing director at Premier Energies, said, “This joint venture will leverage the best of both companies’ resources and knowledge to tap the largely unaddressed demand for US cell manufacturing.”

Heliene says the decision to invest jointly in the US solar industry is in direct response to the incentives and tax credits introduced by President Biden’s Inflation Reduction Act (IRA).

Researchers hope the palm-size solar-powered robot will help monitor remote disasters and link telecommunications systems

Watch the world’s tiniest solar-powered robot take flight

,

When disaster strikes in a remote location—an oil spill, for example—scientists and officials need eyes in the skies to monitor conditions from afar. Drones can swoop in to help, but short battery lives can limit their usefulness. Enter ColoumbFly, the world’s lightest and smallest solar-powered flying robot. Described today in Nature, researchers hope its design could inspire a new generation of robotic fliers that can link Wi-Fi networks, send photos, and accomplish other remote-monitoring tasks for long periods of time.

CoulombFly, designed by a team at Beihang University, is palm size and weighs just a little more than 4 grams. Unlike traditional tiny flying machines that use an electrified magnet to power their rotors, the CoulombFly’s motor is powered by the so-called Coulomb force—the force between electrically charged particles at rest. Here, a solar cell generates electricity and creates an electric field between oppositely charged plates aligned in a circle. The opposing charges, like repelling magnets, generate enough force to turn the blades of a rotor. That creates enough torque to propel the robot off the ground.

Researchers in Germany have developed a groundbreaking new light-harvesting system that could drive a huge leap in solar cell efficiency

New light-harvesting system could revolutionize solar energy, researchers claim

WHAT JUST HAPPENED? The solar energy revolution might be about to shift into an even higher gear. Researchers in Germany have developed a groundbreaking new light-harvesting system that could drive a huge leap in solar cell efficiency by absorbing light across the entire visible range.

For years, solar tech has been hamstrung by some fundamental limitations. Traditional silicon-based solar cells can absorb light across the entire visible spectrum, which is great, but they do so “weakly.” They also need to be thick – we’re talking micrometers – to soak up enough photons to generate meaningful electricity. That added bulk makes them heavier, pricier, and harder to integrate seamlessly into buildings and vehicles.

New record for perovskite-silicon cell is more than 7 per cent more efficient than a standard silicon cell

Solar panel world record achieved with ‘miracle material’

A new efficiency world record for converting sunlight into electricity has been set, in what researchers claim is a huge boost for renewable energy.

Researchers at Longi, the world’s biggest solar panel manufacturer, achieved a 34.6 per cent power conversion efficiency using a tandem perovskite-silicon solar cell, beating the previous record by 0.7 per cent.

The new record is also more than 7 per cent more efficient than the record for a standard silicon solar cell, which is found in most commercial solar panels.

A new $800 million solar cell manufacturing facility is moving into southern Indiana that will bring 1,200 jobs over the next several years.

$800 million solar cell manufacturing facility being built in southern Indiana

A new $800 million solar cell manufacturing facility is moving into southern Indiana.

In a news release Monday, Gov. Eric Holcomb announced that Canadian Solar plans to build a new plant at the River Ridge Commerce Center in Jeffersonville. The plant will bring 1,200 jobs over the next several years. It’s the company’s second plant in the U.S.

Production is expected to begin by the end of 2025 on solar photovoltaic (PV) cells to supply the company’s new module assembly facility announced earlier this year in Texas.

Caelux announced the successful closure of a $12M funding that will be used to open a 100MW perovskite-coated glass factory in California.

Commercial-scale perovskite manufacturing soon starting in United States

Perovskite development has been a major R&D buzzword in the solar industry for the last decade. The nanomaterial absorbs more of the light spectrum than a traditional silicon solar cell. Layering perovskites with other solar technologies would lead to more powerful and efficient solar panels at a relatively low added cost. Researchers have been testing various applications of perovskites — whether spin-coated, sprayed or painted onto a substrate. California-based Caelux has found success coating its perovskite design onto glass, with the final product easily incorporating into existing silicon solar panel manufacturing lines.

Caelux today announced the successful closure of a $12 million Series A3 funding round led by Temasek with participation from Reliance New Energy, Khosla Ventures, Mitsui Fudosan and Fine Structure Ventures, bringing Caelux’s total raised funding to $24 million. Caelux will use this funding to open a 100-MW perovskite-coated glass factory in Baldwin Park, California, just outside Los Angeles.

Solar4America, a wholly owned subsidiary of SPI Energy, plans to begin manufacturing N-type heterojunction (HJT) solar cells in the US.

Heterojunction solar cell factory to be built in Sacramento

Solar4America, a wholly owned subsidiary of SPI Energy, plans to begin manufacturing N-type heterojunction (HJT) solar cells in the United States.

This follows the company’s January announcement to increase solar module production to 2.4 GW at its factory in Sacramento, California. While the US Inflation Reduction Act has thus far incentivized many module manufacturers to begin production in the United States, cell and wafer manufacturing has yet to ramp up.

“The production of HJT solar cells aligns with our commitment to providing cutting-edge renewable energy technology while reducing carbon footprints globally,” said Denton Peng, chairman and CEO of SPI Energy.

Scientists break world record for solar power window material

Scientists have achieved a new world record for a next-generation solar cell, which holds the promise for novel applications like building-integrated and window solar panels.

The breakthrough follows two years of research from the Hong Kong Polytechnic University into organic solar cells (OSCs), which until now have been too inefficient and costly to be used widely in practical applications.

The research team invented a new technique to boost the stability of OSCs, achieving a power-conversion efficiency of 19.3 per cent.

New solar cell turns any surface into power source

MIT engineers have developed ultralight fabric solar cells that can quickly and easily turn any surface into a power source. These durable, flexible solar cells, which are much thinner than a human hair, are glued to a strong, lightweight fabric, making them easy to install on a fixed surface. They can provide energy on the go as a wearable power fabric or be transported and rapidly deployed in remote locations for assistance in emergencies. They are one-hundredth the weight of conventional solar panels, generate 18 times more power-per-kilogram, and are made from semiconducting inks using printing processes that can be scaled in the future to large-area manufacturing.

Because they are so thin and lightweight, these solar cells can be laminated onto many different surfaces. For instance, they could be integrated onto the sails of a boat to provide power while at sea, adhered onto tents and tarps that are deployed in disaster recovery operations, or applied onto the wings of drones to extend their flying range. This lightweight solar technology can be easily integrated into built environments with minimal installation needs.
