Abstract

The effects of annealing at high temperatures on polymer solar cells consisting of conjugated poly(3-hexylthiophene) (P3HT) and fullerene derivative [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) composites with high concentrations of 3 and 5wt% are reported. As compared with as-casted samples, the optical intensity in absorption spectra for the 3wt% film was improved after annealing at temperatures of 110-150 °C, and the device made of 5wt% blend film after annealing at 150 °C demonstrated nearly sevenfold improvements in both short-circuit current density (Jsc) and power conversion efficiency (PCE).
