Effect of electrode geometry on photovoltaic performance of polymer
solar cells

Meng Li, Heng Ma, Zhaokui Wang, Chuankun Wang, Yurong Jiang, Ning Liu
This paper investigates the impact of electrode geometry on the performance of polymer solar cells (PSCs). Four types of negative electrodes with equal area (0.09 cm2) but different shape (round, oval, square, and triangular) are evaluated with respect to short-circuit current density, open-circuit voltage, fill factor, and photoelectric conversion efficiency of PSCs. The results show that the device with round electrodes gives the best photovoltaic performance; in contrast, the device with triangular electrodes reveals the worst properties. Maximum almost twice increase in PCE with round electrode was obtained in the devices compared with that of triangular electrode. sharper electrode edges may lead to an degrade the performance of PSCs. The electrode boundary curvature influences the performance of PSCs
