Material crystallinity is the overriding factor in the determination of the photoelectric properties of absorber materials and the overall performance of photovoltaic device.Nevertheless,in Cu2ZnSn(S,
In the present work,we find a method of fabricating Cu2Zn1-xCdxSn(S,Se)4(CZCTSSe)solar cells through a surface Cd-doping of CuZnSnS precursor film first and then selenization.
