We present measurements of the outdoor stability of PCDTBT:PC71BM based bulk heterojunction organic solar cells for over the course of a year. We find that the devices undergo a burn-in process lasting 450 hours followed by a TS80 lifetime of up to 6200 hours. We conclude that in the most stable devices, the observed TS80 lifetime is limited by thermally-induced stress between the device layers, as well as materials degradation as a result of edge-ingress of water or moisture through the encapsulation.
我们展示了基于聚[2,6-(4,4-双十二烷基-4H-环戊二烯并[2,1-b:3,4-b']二噻吩)-alt-4,7-(2,1,3-苯并噻二唑)]（PCDTBT）和[6,6]-苯基-C71-丁酸甲酯（PC71BM）的体异质结有机太阳能电池在一年时间内的户外稳定性测量结果。我们发现，这些器件经历了一个持续450小时的老化过程，随后的TS80寿命长达6200小时。我们得出结论，在最稳定的器件中，观察到的TS80寿命受器件层之间热致应力以及水或湿气通过封装边缘进入导致的材料降解的限制。
