제목 Effects of selenization time on the properties of Cu2ZnSnSe4 thin film solar cell
초록 The kesterite Cu2ZnSnSe4 (CZTSe) 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 30W power at room temperature. As-deposited metallic precursors were placed in a graphite box with Se pellets and selenized using rapid thermal processing furnace at various time (3min~20min) at 540℃ without using a toxic H2Se gas. Effects of annealing time on the microstructure, crystallinity, electrical properties and cell efficiency were investigated by field emission scanning electron microscope(FE-SEM) and X-ray diffraction (XRD), I-V measurement system and solar simulator. Further details about effects of different selenization time on CZTSe films will be discussed.
