摘要：

Cu2ZnSnS4 thin films were prepared by photo-chemical deposition (PCD) from aqueous solution containing CuSO4, ZnSO4, SnSO4 and Na2S2O3. The compositional ratio of the films was dependent little on pH of aqueous solution and the surface of the samples became smooth by use of aqueous filter. A sample annealed at 400 degrees C was a p-type semiconductor and showed photoconductivity. This is the first observation of photo-conductivity from semiconductor films deposited by PCD, to the best of our knowledge.
