Technology and R&D

Maxeon said it has achieved a 24.7% efficiency rating for a full-scale Maxeon 7 solar panel using its IBC technology. The US National Renewable Energy Laboratory (NREL) confirmed the result.

Dutch solar manufacturer Solarge has unveiled two versions of its lightweight mono-PERC solar panels for rooftop applications. The module have power outputs between 470 W and 520 W and efficiencies ranging from 17.4% to 19.2%.

ZincFive is supplying battery systems for Advanced Power & Energy’s hydrogen-fueling microgrid and pilot DC fast-charging station in Greenville, Pennsylvania

NGK Insulators has switched on 1 MW/5.8 MWh of NAS batteries under a demonstration project to assess the performance of stationary storage at a site operated by Korea Electric Power Corp. (KEPCO).

Mitsubishi Electric has launched a demonstration experiment to assess the efficiency of heat pumps in demand-response control on the Aran Islands in Ireland and San Pietro Island in Italy. As part of the European Union’s REACT project, solar, wind, and storage solutions will also be implemented to enhance the energy self-sufficiency of isolated islands.

Hong Kong Polytechnic University researchers have developed a binary organic solar cell (OSC) with a record power conversion efficiency of 19.31%. They invented a non-monotonic intermediate state manipulation strategy to lower the non-radiative recombination loss and boost efficiency.

A Dutch research group has used a series of techniques from the automotive industry to develop a novel methodology to repair glass in double-glass solar panels. Their experimental work represents the step towards transforming glass-damaged solar panels from waste into valuable products.

Avancis has set a new world record for a copper, indium, gallium, and selenium (CIGS) solar panel with an integrated series connection of 30 cm x 30 cm, achieving an efficiency of 20.3%. The German manufacturer’s accomplishment has been validated by the US National Renewable Energy Laboratory.

Germany’s development bank, KfW, is financing a new minigrid project in Senegal with a $138.8 million loan.

Scientists in the United Kingdom have proposed using orbiting solar reflectors to enhance the electricity yield of terrestrial solar power plants. They claim this new technology may be particularly beneficial for improving generation at dusk and dawn, when irradiance is lower.
