제목 Influence of Zn content on structural, morphological and electrical properties of Cu2ZnSnSe4 based thin film solar cells
초록 In this study, Cu2ZnSnSe4 (CZTSe) based thin film solar cells were synthesized by selenization of sputtered Cu/Sn/Zn metallic precursors on Mo coated soda lime glass substrate in Ar atmosphere. Cu/Sn/Zn metallic precursors were deposited by DC magnetron sputtering process with increasing Zn content at room temperature. As-deposited metallic precursors and Se pellets were placed in a graphite box and then selenized using rapid thermal annealing system without using a toxic H2Se gas. Effects of Zn content on structural, morphological and electrical properties have been studied. Morpholgiy of absorber layer were investigated by field emission scanning electron microscope(FE-SEM). Structural, electrical properties and cell efficiency were investigated by Raman Scattering and X-ray diffraction (XRD), I-V measurement system and solar simulator. Further details about influence of Zn content on CZTSe based thin film solar cells will be discussed.
