Void and secondary phase control method of CZTSSe solar cell with metal precursor |
| 초록 |
Cu2ZnSn(S,Se)4 (CZTSSe) thin-film solar cell is composed of earth-abundant non-toxic elements. Also, it has a high light absorption coefficient of over 104 cm−1 and an appropriate band gap of 1-1.5 eV. However, the structure of CZTSSe is thermodynamically unstable compared with CIGS structure because the region where the stable phase is generated is very narrow, resulting in a large number of secondary phases. Especially The metal precursor is voided during the heat treatment process and during the formation of the ZnSSe layer. In this study, the voids and the secondary phase were eliminated by controlling the structure of the precursor and the annealing atmosphere.
