Abstract

In this work, we investigate the performance of Bulk Heterojunction (BHJ) Organic Solar Cells fabricated with P3HT films blended with varying weight fractions of PCBM[70]. To determine the optimal composition, P3HT:PCBM[70] blends at three different ratios (1:0.84, 1:1 and 1:1.21, wt%) were fabricated. The electrical parameters were extracted from the current - voltage characteristics (I-V) under dark and illuminated conditions. The degradation mechanisms involved in the devices were studied.
