Organic bulk heterojunction solar cells utilize the donor–acceptor approach to amplify the charge photogeneration via interfacial charge-transfer (CT) states. A detailed modeling of the CT energetics is required to understand the performance limitations of organic photovoltaic devices today. However, general questions regarding the CT state are still under dispute. In this Perspective, we want to focus on energetic CT disorder, which can be separated into dynamic and static broadening. Both contributions uniquely affect the solar cell properties, and we will highlight current research results regarding their dominance over the CT state energy.

动态和静态无序在有机体异质结太阳能电池中电荷转移状态的作用

有机体异质结太阳能电池利用施主-受主方法通过界面电荷转移 (CT) 状态放大电荷光生。要了解当今有机光伏器件的性能限制，需要对 CT 能量学进行详细建模。然而，关于 CT 状态的一般问题仍然存在争议。在这个观点中，我们想关注高能 CT 障碍，它可以分为动态和静态展宽。这两项贡献都对太阳能电池特性产生了独特的影响，我们将重点介绍当前关于它们对 CT 状态能量的主导地位的研究结果。
