Potassium doping effect on Cu2ZnSn(S,Se)4 thin film absorber layer deposited via spray pyrolysis

This article reports on the role of potassium (K) as dopant in Cu2ZnSn(S,Se)4, CZTSSe thin film in context of optical properties. Thin film precursor solution is prepared in dimethyl sulfoxide (DMSO) solvent, and doped by K with six different concentrations. The prepared solution are deposited on he...
