摘要/Abstract

摘要：

制备了结构为：ITO/PEDOT：PSS／P3HT+PCBM/LiF/Al的有机太阳能电池，研究退火对电池性能的影响，实验发现：经过60 min 150⁰ C退火处理后，器件开路电压（Voc）为0.57 V，短路电流密度（Jsc）达到6.32 mA·cm-²，填充因子（FF）达到0.55，光电转换效率（η_p）达到2.01%，器件性能明显提高。探讨了退火对电池性能影响的内在原因。

Abstract:

The organic solar cells with structure as ITO/PEDOT: PSS/P3HT + PCBM/LiF/Al are prepared to study the effect of annealing treatment on the property of battery. These devices are treated at 150 益for 60 min in an ambient atmosphere and the best power conversion efficiency（η_p）of 2.01％ is obtained at an open circuit voltage（Voc）of 0.57 V，a short circuit current density（Jsc）of 6.32 mA·cm-2，and a fill factor（FF）of 0.55. The device performance is significantly improved by thermal annealing. At last, the internal cause of annealing affecting the property of battery is discussed.

Key words: organic solar cells, annealing, bulk heterojunction, photoelectric conversion efficiency
