A power conversion efficiency of 6.48% was achieved for polymer solar cells based on poly(3‐hexylthiophene) (P3HT) as donor and indene‐C 60 bisadduct (ICBA) as acceptor with an open‐circuit voltage of 0.84 V, a short‐circuit current of 10.61 mA/cm 2 , and a fill factor of 72.7% under irradiation at AM1.5G, 100 mW/cm 2 at the optimized conditions of P3HT:ICBA = 1:1 (w/w), solvent annealing and pre‐thermal annealing at 150 °C for 10 minutes.
