Abstract:In this study, Cu2ZnSnS4 precursor films are directly fabricated on the surface of FTO glass substrates using a hydrothermal method, and then Cu2ZnSn(SxSe1-x)(4) films are obtained through sulfurization or selenization annealing process. The influences of hydrothermal reaction time and annealing conditions on the morphology, crystallinity, energy band gap and photo-electrical performance of Cu2ZnSn(SxSe1-x)(4) films are studied. The findings show that chemical compositions can be tuned via tailoring annealing conditions and photocurrent increases with the increase of hydrothermal reaction time and the introduction of Se.
