本文研究了有机体异质结太阳能电池的热稳定性，特别关注光伏参数和活性层形貌的热老化。通过IV表征确定了一组本体异质结太阳能电池的光伏参数，并利用透射电子显微镜（TEM）研究了它们的本体形态。可以在热处理下的短路电流的退化和相应的本体形态的变化之间建立联系。通过使用具有更高玻璃化转变温度的聚合物，提出了一种可能的提高体异质结太阳能电池的热稳定性的方法。
This paper investigates the thermal stability of organic bulk heterojunction solar cells, with a special focus on the thermal ageing of both photovoltaic parameters and morphology of the active layer. The photovoltaic parameters of a set of bulk heterojunction solar cells were determined by IV-characterization and their bulk morphology was investigated with transmission electron microscopy (TEM). A link could be made between the degradation of the short circuit current under a thermal treatment and the corresponding change in bulk morphology. A possible improvement of the thermal stability of bulk heterojunction solar cells is presented through the use of a polymer with higher glass transition temperature.
