本文综述了有机太阳能电池光电响应的模拟方法，重点介绍了一维漂移扩散模拟的应用。我们将讨论如何处理重要的物理过程，并回顾一些必要的实验，以确定设备模拟的输入参数。为了说明漂移扩散模拟的有用性，我们讨论了几个案例研究，解决双极和单极器件中的电荷缺陷对传输的影响，缺陷对重组，器件性能和理想因素的影响。为了说明频域模拟，我们展示了如何确定薄器件的莫特-肖特基图的有效范围。最后，我们讨论了一个例子，其中光学模拟被用来计算接触层中的寄生吸收。
We review the methods used to simulate the optoelectronic response of organic solar cells and focus on the application of one-dimensional drift-diffusion simulations. We discuss how the important physical processes are treated and review some of the experiments necessary to determine the input parameters for device simulations. To illustrate the usefulness of drift-diffusion simulations, we discuss several case studies, addressing the influence of charged defects on transport in bipolar and unipolar devices, the influence of defects on recombination, device performance and ideality factors. To illustrate frequency domain simulations, we show how to determine the validity range of Mott–Schottky plots for thin devices. Finally, we discuss an example where optical simulations are used to calculate the parasitic absorption in contact layers.
