Improvement of the structural and electronic properties of CZTSSe solar cells from spray pyrolysis by a CuGe seed layer [PDF]

, 2017
We have produced CZTSSe solar cells by a sequential growth process. First, CZTS precursors were deposited on Mo-coated soda lime glass substrates by chemical spray pyrolysis from an aqueous solution containing Cu, Zn and Sn metal salts and thiourea. In a

Device Characteristics of Band gap Tailored 10.04% Efficient CZTSSe Solar Cells Sprayed from Water-Based Solution

, 2019
A diverse S/(S + Se) ratio of Cu2ZnSn­(Sx,Se1–x)4 (CZTSSe) thin-film solar cells is derived by the water-based spray pyrolysis approach. By fine-tuning the S/(S + Se) ratio, base CZTSSe device efficiency has significantly improved from 7.02 to 10.04% by ...
