Novel tin selenide solar cell design promises 36.45% efficiency

Tin selenide solar cells have so far reached limited efficiencies in real applications. Bangladeshi scientists claim to have found a way to drastically improve their performance by adding a copper/indium/selenium (CIS) thin-film layer and a back surface field (BSF) layer.Researchers at the University of Rajshahi in Bangladesh have made a new attempt to design solar cells based on a tin selenide (SnSe) absorber and claim their new solution may lead to the development of highly efficient devices. "SnSe has innate p-type electrical conductivity which raises the possibility of using it as an absorber ...
