摘　　要：Effect of the device fabrication conditions on photovoltaic performance of the polymer solar cells based on poly（3-hexylthiophene） （P3HT） as donor and indene-C70 bisadduct （IC70BA） as acceptor was studied systematically. The device fabrication conditions we studied include pre-thermal annealing temperature, active layer thickness, and the P3HT ： IC70BA weight ratios. For devices with a 188-nm-thick active layer of P3HT ： ICToBA （1 ： 1, w ＇ w） blend film and pre-thermal annealing at 150 ℃C for 10 rain, maximum power conversion efficiency （PCE） reached 5.82% with Voc of 0.81 V, Isc of 11.37 mA/cm2, and FF of 64.0% under the illumination of AM1.5G, 100 mW/cm2.Effect of the device fabrication conditions on photovoltaic performance of the polymer solar cells based on poly（3-hexylthiophene） （P3HT） as donor and indene-C70 bisadduct （IC70BA） as acceptor was studied systematically.
