A US study has suggested the raised energy yield of bifacial perovskite devices effectively means they could have a lower environmental impact than conventional crystalline cells. The researchers considered single-junction cells with high and low bandgaps and similar, multi-junction devices with two and four-terminal structures.Scientists from four U.S. universities have said bifacial perovskite PV cells have the potential to become more environmentally friendly than conventional crystalline silicon devices, due to their increased energy yield. The researchers analyzed the environmental impact ...Den vollständigen Artikel lesen ...
