英文摘要：

This paper reported the effect of annealing on photoelectric performance of organic solar cell （OSC） based on poly （3-hexylthiophene） （P3HT） and [6,6]-phenyI C61 butyric acid methyl ester （PCBM）. The results showed that the crystallizing and the transmission of P3HT/PCBM film were improved, the reflectivity was deceased. The value of photoelectric conversion efficiency （PCE） achieved the largest value with 140℃ temperature annealing. The voltage and current density decreased as a function of time by a similar exponential function, and the fill factor changed with a zigzag pattern. For PCE, it decreases rapidly in earlier stage. With time increasing, the decay of PCE became planar.
