Abstract
Degradation in a high efficiency polymer solar cell is caused by the formation of states in the bandgap. These states increase the energetic disorder in the system. The power conversion efficiency loss does not occur when current is run through the device in the dark but occurs when the active layer is photo-excited.
摘要
在高效聚合物太阳能电池中，降解是由带隙中状态的形成引起的。这些状态增加了系统的能量无序性。当电流在黑暗中流过器件时，不会发生功率转换效率损失，而是在活性层被光激发时发生。
