| Abstract | CZTSe solar cells with different elemental ratios are compared for their photo-response with low and high illumination densities. Elemental ratios are found not only affecting the defect density, but also Mo/CZTSe/CdS band alignment. Higher Sn/Cu and lower Zn ratio was found more immune to EQE droop at high power illumination, although it yields lower EQEs at low power level. Furthermore, inhomogeneity in thermal conductivity was found within the film. The findings suggest the potential to modify Zn and Sn ratios adapting to different operation conditions and applications. |
