Abstract

Copper Indium Diselenide (CuInSe2) thin films of different Cu-In layers were prepared using sequential elemental evaporation technique. Respectively, the selenization within a close spaced graphite box resulting in quality CuInSe2 (CIS) films was developed. The comparative analysis of crystalline properties evaluated by energy-dispersive X-ray spectroscopy (EDX), scanning electron microscope (SEM), X-ray diffraction (XRD), Raman scattering measurements is presented here. A photovoltaic efficiency of the heterojunction is compared with that the structure of SLG/Mo/CuInSe 2/CdS/ZnO/AZO/Al photovoltaic devices. Introducing In-excess CIS film increase the efficiency to 4.62%, because of the current density and open circuit voltage were improved.
