Cu 2 ZnSnS 4 thin films were prepared by photo-chemical deposition (PCD) from aqueous solution containing CuSO 4 , ZnSO 4 , SnSO 4 and Na 2 S 2 O 3 . 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°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.
