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.

基于PCDTBT的太阳能电池：在实际条件下可运行一年。

我们介绍了一年中基于PCDTBT：PC71BM的整体异质结有机太阳能电池的室外稳定性的测量结果。我们发现设备经历了持续450小时的老化过程，其TS80寿命长达6200小时。我们得出的结论是，在最稳定的器件中，观察到的TS80寿命受到器件层之间的热诱导应力以及由于水或水分通过包封边缘吸收而导致的材料降解的限制。
