Abstract:Owing to the fascinating optoelectronic and photovoltaic properties,
perovskite halide materials have attracted much attention for solar
cells applications. Using the first-principles approaches, we present
here results of calculations of the strain effects on electronic and
optical properties as well as carriers mobility of
CsSnI double perovskite. The
calculated band gap energy of unstrained
CsSnI is about 1.257 eV when using
Tran-Blaha modified Becke Johnson (mBJ) exchange potential that is in
fair agreemen… Show more
