German scientists have developed a solar cell with multiple quantum wells to enable higher levels of photocurrent. The 3.4%-efficient device could be used for glass facades in buildings and windows, sunroofs in vehicles, and greenhouses for agrivoltaics.Researchers from the German Aerospace Center (DLR) have fabricated a semitransparent solar cell based on ultra-thin hydrogenated amorphous multiple quantum wells (MQWs) made of silicon and germanium (Si/Ge). "Our novel semi-transparent solar cell technology could afford several integration opportunities into diverse applications like glass façades ...Den vollständigen Artikel lesen ...
