EFFECT OF CHEMICAL TREATMENT OF THIN FILMS Cu2ZnSnSe4 ON PHOTOLUMINESCENCE OF SOLAR CELLS CREATED ON THEIR BASIS

Abstract

The effect of etching regimes of thin films of Cu2ZnSnSe4 (prior to the deposition of CdS) on the bandgap (Eg) and photoluminescence (PL) spectra were studied by examining solar cells with the structure ZnO/CdS/Cu2ZnSnSe4/Mo/glass using PL and PL-excitation tech-niques
