CEA-INES researchers and Enel have developed a new solar cell with an active area of 9 cm² and an open-circuit voltage above 1,900 mV. Their results improve on the 27.1% efficiency they achieved for the same kind of cell in June.Researchers at France's National Solar Energy Institute (INES) - a division of the French Alternative Energies and Atomic Energy Commission (CEA) - and Italian renewables specialist Enel Green Power claim to have achieved a power conversion efficiency of 28.4% for a two-terminal tandem perovskite-silicon solar cell. The European Solar Test Installation of the European ...Den vollständigen Artikel lesen ...
