Scientists make first attempt to design solar cells based on kusachite

Indian scientists have designed a thin-film solar cell that uses a mineral made of binary copper(II) and bismuth(III) oxide. They identified a cell design with a tin sulfide buffer layer that offers efficiencies close to 27.7%.Scientists from the Indian Institute of Technology Indore have proposed a new way to fabricate thin-film solar cells based on kusachiite (CuBi2O4), an extremely rare binary copper(II) and bismuth(III) oxide that was recently discovered in Okayama prefecture, Japan. "There are two previous reports on using kusachiite as a light harvester," researcher Vishesh Manjunath told ...
