Recently, Organic solar cells (OSCs) have attracted attention even if they have several drawbacks because of potential properties such as felxible, lightweight, transparency, and roll-to-roll processing. Many researchers have made much effort to improve their power conversion efficiency (PCE) via synthesize new conjugated polymer, and introduce interlayer. In this research, we used a ZnO nanofilm doped with a viologen derivative (V-2OH) as the cathode of an inverted OSCs which is used to provide a simple modification method of ZnO work function for effective collection of electron. This modification has increased of the short-circuit current in the OSCs, leading to an overall improve in PCE. Herein we investigate the effect of viologen derivatives on photovoltaic performances. |
