Combining two semiconductor thin films into a tandem solar cell can achieve high efficiencies with a minimal environmental footprint. Teams have now presented a CIGS-perovskite tandem cell that sets a ...

An international group of scientists has proposed a new copper indium gallium selenide (CIGS) solar cell structure using antimony trisulfide (Sb2S3) as the back surface field (BSF) layer.

Scientists have developed a technique for producing AZO and i-ZnO/AZO bilayer structures ... the integrity of the solar cell layers. “In traditional high-efficiency CIGS thin-film solar cells ...

Until recently, chalcopyrite-based solar cells have achieved a maximum energy conversion efficiency of 23.35%, as reported in 2019 by Solar Frontier, a former Solar Energy company based in Japan.
