Abstract
We synthesized fullerene derivatives with carbazole and fluorene containing para butyl substitution, which are called Cbz-mono and Flu-mono. We study their electrochemical properties and the performance of photovoltaic devices of P3HT ：fullerene derivatives with different blend ratios, solvent, and annealing temperature. The optimized conditions of P3HT/Cbz-mono device is P3HT：Cbz-mono = 1：0.7 in a mixed solvent of oDCB and TCB, and the the open circult voltage（Voc）is 0.69 V、the short circuit current（Jsc）is 6.02 mA/cm2、the fill-factor is 60.92%, and the power conversion efficiency is 2.53%. Under the optimized conditions of P3HT/Flu-mono device is P3HT：Cbz-mono = 1：0.7 in oDCB, shows the the open circult voltage（Voc）of 0.73 V. The short circuit current（Jsc）is 6.82 mA/cm2. The fill-factor is 55.89%. The power conversion efficiency is 2.78%. More over, we used the electro-polymerization of Cbz-mono was applied for 、.
