Annotation This paper describes the fabrication of P3HT based bulk heterojunction solar cell using ZnS nanopar-ticles of sphalarite and wurtzite crystal structure and discusses their photovoltaic characteristics. It is found that the device of P3HT : ZnS can give higher Voc and surface modified wurtzite ZnS is able to give higher Voc (~ 1.3 V) as well as higher current density (229.60 μA/cm2) and comparable efficiency (0.032 %). Active layer (P3HT : ZnS) showed a broad optical absorption from 320 nm to 650 nm and it is seen that the absorption intensity increased in the blend than the pristine P3HT.
