Fabrication and Characterization of ZnSCubic : P3HT, ZnSHexa : P3HT and ZnSHexa : P3HT:PVA-Ag Bulk Heterojunction Solar Cells

摘要

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