Abstract

ZnO is a widely used electron transport material in third generation solar cells. Intrinsic defects arising from different synthetic methods and conditions lead to different fluorescent colors. The defect mechanisms have been explored in the literature, but their impact on organic photovoltaic (OPV) cell performance is rarely reported. Herein, three different ZnO nanoparticles showing blue, green, and yellow emission colors are synthesized and incorporated into OPV cells. The as-cast ZnO films result in vastly different OPV performances. It is found the sodium acetate as the byproduct of the synthesis can significantly influence the interfacial contact. After removing the impurity via rinsin..
