Cu2ZnSn(S, Se)4 (CZTSSe) is emerged as a promising material because of non-toxic, inexpensive and earth abundant more than Cu(In, Ga)Se2. The highest conversion efficiency of CZTSSe is 11.1 % at IBM based on hydrazine process [1]. We have achieved CZTSSe thin-film solar cell 8% conversion efficiency by sputtering process. CZTSSe thin-films show different efficiency depending on selenization process...
We have studied structural, electrical, photoelectric and optical properties of two series of polymorphous silicon thin films deposited by PECVD with variation of silane and hydrogen gas mixture pressure and substrate temperature. The change of gas pressure did not affect substantially films' Raman spectra, but resulted in changes of photoconductivity values and spectral dependencies of absorption...
