摘　　要：Copper tin sulfide （Cu2SnS3） was a potential earth abundant absorber material for photovoltaic device application. In this contribution, triclinic Cu2SnS3 film with phase pure composition and large grain size was fabricated from a hydrazine solution process using Cu, Sn and S as the precursors. Absorption measurement revealed this Cu2SnS3 film had a direct optical band gap of 0.88 eV, and Hall effect measurement indicated the film was p-type with hole mobility of 0.86 cmE/Vs. Finally Mo/Cu2SnS3/ CdS/ZnO/AZO/Au was produced and the best device efficiency achieved was 0.78%. Also, this device showed improved device performance during ambient storage. This study laid some foundation for the further improve- ment of Cu2SnS3 solar cell.Copper tin sulfide （Cu2SnS3） was a potential earth abundant absorber material for photovoltaic device application.
