　　经过对 P3HT／PCBM 活性层薄膜退火，发现光的透射率增大，光的反射率减小．活性层的 X 射线衍射图谱分析表明，经过不同的退火时间，薄膜内结晶度不同，结果导致器件的量子效率有所不同．该器件在140℃的温度下，经过30 min 退火，有机太阳能电池的短路电流达到0．75 mA／cm 2，光电转化效率为0．03464％，比较其他退火时间，该工序能量转换效率最高．

The effect of different annealed time on organic solar devices were investigated .Results indicate that the light transmissivity of the P3HT/PCBM active film is improved and the reflectivity deceases in the annealing process . The X-ray diffraction analysis reveals that the degree of crystallite is different in those films by different annealing time . It results in a different quantum efficiency with the different devices .The short-circuit current is 0.75 mA/cm 2 when the annealing temperature is 140 ℃ for 30 min.The photoelectricity conversion efficiency of the devices is 0.034 64%which is the largest one compared with other devices .
