A conjugated D-A copolymer (P) having benzodithiophene donor and benzo[ 1,2,5] thiadiazole acceptor was employed as a p-type hole transporting material in solid state organic-inorganic hybrid solar cells and compared with the P3HT hole transporting material. In these device we have used organo-lead halide (CH3NH3PbI3) synthesized by us, as light harvester. The power conversion efficiency (PCE) of 6.64% is achieved for the solar cell with P which is higher than that for P3HT (4.24%). The increase in PCE is mainly due to the enhancement in FF and V-oc and attributed to higher mobility of hole for conjugated copolymer than P3HT. (C) 2014 Published by Elsevier Ltd.
