摘　　要：The efficiency of the poly（3-hexylthiophene） （P3HT） and [6,6]-phenyl C61-butyric acid methyl ester （PC61BM） based organic solar cells was enhanced by using 1,2,4-trichlorobenzene （TCB） as a processing additive to control the blend morphology. The addition of TCB improved the arrangement of P3HT which resulted in good phase separated blend films. Correspondingly, the optimized solar cells showed a power conversion efficiency （PCE） of 4.17% with a fill factor （FF） of 0.69, which were higher than those of common thermal annealing devices （PCE 3.84%, FF 0.67）. The efficiency was further improved to 4.74% by thermal annealing at 150 ℃for 10 min with a higher FF of 0.74.The efficiency of the poly（3-hexylthiophene） （P3HT） and [6,6]-phenyl C61-butyric acid methyl ester （PC61BM） based organic solar cells was enhanced by using 1,2,4-trichlorobenzene （TCB） as a processing additive to control the blend morphology.
