Abstract
Hybrid polymer solar cells based on a conjugated polymer donor and a ZnO acceptor have drawn increasing attention because of the excellent electron-transfer performance and various nanostructures of the ZnO material. In the present study, ZnO nanorods were grown on an indium tin oxide-coated glass from a solution of Zn2+ via a hydrothermal route. Suitable growth conditions, including the Zn2+ concentration and growth time, were selected based on the scanning electron microscopy characterization. The poly [1-methoxy-4-(2-ethylhexyloxy-2,5-phenylenevinylene)] solution was filtered into vertically lined ZnO nanorods to form an active layer of the hybrid bulk-heterojunction solar cells. The hybrid polymer solar cell exhibits low efficiency of 0.045 %, which may be attributed to the defects in the ZnO nanorods and the high interior resistance of the cell.
