Midsummer and researchers from the University of California, Los Angeles (UCLA), says that their new tandem PV cell is suitable for the company's Duo production equipment, which makes 56 mm x 156 mm CIGS cells on a flexible stainless steel substrate.UCLA researchers and Midsummer, a Swedish building-integrated PV (BIPV) module manufacturer, claim to have demonstrated a four-terminal (4T) tandem solar cell. It is based on a top cell made of perovskite and a bottom cell relying on copper, indium, gallium and selenium (CIGS). "The cell is based on a perovskite top cell that has been optimized for ...Den vollständigen Artikel lesen ...
