摘要：

We report all-polymer solar cells (PSCs) based on a polymer blend of poly[3-(10-n-octyl-3-phenothiazine-vinylene)thiophene-co-2,5-thiophene] as donor and poly[1,4-dioctyloxyl-p-2,5-dicyanophenylenevinylene] as acceptor. Strong photoluminescence quenching is observed in the polymer blend indicating the photoinduced charge transfer occurs between the two polymers. The power conversion efficiency of the PSC was improved from 0.41% to 0.8% after 120 degrees C postannealing, under the illumination of AM 1.5, 100 mW/cm(2). We attribute the improved efficiency to better morphological features of the photoactive layer after thermal annealing.
