Scientists in China developed a novel swelling process to detach glass and EVA backsheets from solar modules at the end of their lifecycle. The technique utilizes an ester of a dicarboxylic acid known as dibasic ester. It reportedly prevents excessive cracking of solar cells.

The consortium says it intends to develop a simplified approach and best practices to produce 2T perovskite-silicon tandem solar products. The modules should have a bifacial design, glass-glass encapsulation, and a power output of over 300 W/m2.

French developer Valeco has deployed an agrivoltaic installation on a fodder field and has found out it offers benefits for the quality and quantity of the crop, as well as for sheep grazing under the solar panels.

A research group in China has designed a perovskite solar cell with a new ligand known as 3-amidinopyridine. These molecules are reportedly able to efficiently reduce anion vacancy defects, thus ensuring higher power conversion efficiency and remarkable stability.

South Korean researchers have developed a heat trading system including a ground-source heat pump, solar thermal collectors, a fuel-cell system, and two heat storage tanks for district heating at hours of peak solar production.

Tractebel, DEME, and Jan De Nul will deploy a pilot offshore floating PV facility off the Belgian coast in the summer. The Seavolt floating platform is reportedly able to withstand difficult offshore conditions.

Brazilian scientists have calculated the potential for floating solar generation in Brazil. The results show an installed potential of 43 GW for all of Brazil, with the state of Minas Gerais leading with 6 GW, followed by Bahia with 4.59 GW, and Sao Paulo with 3.87 GW.

Scientists from the University of California, Los Angeles (UCLA), have used an antioxidant known as L-glutathione as an interlayer in an organic PV cell to prevent other materials from oxidizing. The cell has an efficiency of 13.5% and an average visible transmittance of 21.5%. The researchers said it is suitable for applications in solar greenhouses.

Technique Solaire plans to analyze animal behavior in outdoor poultry farms covered with solar panels linked by nets. The setup could be potentially beneficial for the birds and the quality of their meat.

Fraunhofer ISE has presented the results of retrofit heat pump installations in multi-family homes in Germany. One demonstrator featured rooftop solar PV and a multi-source heat pump developed in partnership with Viessmann. It uses air and geothermal as heat sources.
