Technology and R&D

French start-up Rosi Solar has developed an industrial solution claimed to be capable of recovering high purity silicon, silver and copper contained in end-of-life PV modules. The company’s technology is based on a pyrolysis process that makes it possible to isolate the different metals from the cells.

Greenko Group has agreed to provide Ayana with 6GWh of pumped-hydro storage capacity from its project in the Indian state of Andhra Pradesh.

Researchers from the United States have investigated how fuel cells and electrolyzers may be able to operate under intermittent availability provided by both wind and solar and have found that an affordable hydrogen-based system for seasonal energy storage could be achieved at a hydrogen price lower than $3, produced from inexpensive renewable electricity at $0.02/kWh.

Trina Solar, the pioneer of 210mm large format high power PV modules, speaks to pv magazine about its strategy for their deployment. Dr. Zhang Yingbin, Trina Solar’s head of product strategy and marketing, discusses the business solutions Trina provided for its new products, while Todd Li, President of Trina Solar Asia Pacific, shares his views on the PV markets in the Asia-Pacific region.

The triple-junction solar cell is based on indium gallium phosphide (InGaP), gallium arsenide (GaAs), and Germanium (Ge) and is made with a micro-grating made of glass, consisting of a two-dimensional x-framework structure fixed onto the surface of the solar cell. Its operating temperature was found to be 6 degrees Celsius lower than that of a reference cell without the cooling technique.

Verdagy has secured a $25 million investment for its new electrolyzer technology, which provides hydrogen fuel for heavy industrial applications. The membrane-based technology uses large active area cells, high current densities, and broad operating ranges to deliver hydrogen at scale.

Electric vehicles, both fully electric and plug-in hybrid EVs, look set to become dominant in new car sales within years in many parts of the world, but overall changes to car fleets face significant inertia. What impact will this have on the future grid, and where’s the opportunity for solar? Tristan Rayner gets behind the wheel.

The U.S. Department of Energy’s Ames Laboratory launched a new catalyst based on nitrogen and carbon to extract hydrogen from hydrogen storage materials at mild temperatures and under normal atmospheric conditions. Furthermore, South African President Cyril Ramaphosa said that the country is working on attracting new investments in electric vehicles and hydrogen and Norwegian consultancy and classification society DNV launched, together with 18 industry partners, a new Joint Industry Project (JIP) to enhance the standardization for hydrogen production systems that use renewable energy-powered electrolysis to produce green hydrogen.

Scientists have investigated how utility-scale solar may be used to power multistage flashing-brine recirculation (MSF-BR) water desalination plants in Aqaba, Jordan. They found the facility would be sufficient to provide the entire city with drinking water. The proposed system configuration comprises a 30 MW solar plant and a standar MSF-BR unit.

Germany’s Sunfarming is testing the new project design in cooperation with research centers Jülich and the Fraunhofer ISE.
