摘要

摘要本研究探讨了 P3HT:PCBM 体异质结光电设备的降解机制。为此，对在相同条件下制造的八种 P3HT:PCBM 太阳能电池结构的 JV 特性进行了小时研究。结果发现，太阳能电池的功率转换效率（PCE）无一例外地呈指数下降，并在六小时内达到饱和。此外，还研究了器件中光电流的衰减和上升时间。图表的性质否定了光活性薄膜表面氧化和产生陷阱中心的可能性。因此，预计 P3HT 和 PCBM 域的相分离是器件降解的根本原因。

An Experimental Insight into the Reasons for Deterioration of P3HT:PCBM Bulk Heterojunction Solar Cells

Abstract

In the present work, degradation mechanism in P3HT:PCBM bulk heterojunction photo-voltaic devices has been explored. For this purpose, the JV characteristics of eight P3HT:PCBM solar cell structures fabricated under identical conditions, were studied on hourly basis. Without exception, the power conversion efficiency (PCE) of the solar cells is found to fall off exponentially that saturates within six hours. The decay and rise time of the photo-current in the devices were also studied. The nature of the graphs negates the possibility of surface oxidation and generation of trap centers in the photo-active film. Thus, phase separation of P3HT and PCBM domains is expected to be the root cause of device degradation.
