    We report the synthesis of different colloidal CZTSe(4-x)S(x) nanocrystals and their performance in [6,6]-phenyl C61 butyric acid methyl ester (PCBM) based organic/inorganic hybrid bulk heterojunction solar cells. Synthesis of colloidal CuZnSnSe4-xSx were performed and characterized by XRD, TEM, SEM, UV-Visible absorption techniques. Electrochemical and photovoltaic properties were investigated. The best device concept, ITO/PEDOT:PSS/CZTS:PCBM blend (1:10)/Al, showed 280 mu A/cm(2) short circuit current, I-sc with 300 mV open circuit voltage V-oc, and fill factor FF of 0.38.
