A general oxide-based preparation strategy for Cu2MSnS4 (M: Zn, Mn, Cd) thin films and relevant solar cells

In this work, Cu2MSnS4 (M: Zn, Mn, Cd) thin films were successfully prepared by a low-cost and facile oxide-based route. After sulfurization of oxides precursor, the Cu2MSnS4 thin films with composition control exhibit good morphology, analogous crystal structure and suitable bandgaps. Finally the preliminary solar cells based on these films show proper power conversion efficiencies, which demonstrate a high potential application in low cost thin film solar cells.
