Optimum ratio of electron-to-hole mobility in P3HT:PCBM organic solar cells

Abstract

We investigate the influence of different electron-to-hole mobility ratios on the performance of a P3HT:PCBM bulk heterojunction organic solar cell by numerical simulations. We show that using a ratio between electron and hole mobility higher than one, in some particular mobility cases, it can lead to an improvement on the power conversion efficiency.
