15741 目前对钙钛矿太阳能电池所建立的模型,许多都由于某些局限性而忽略了一些物理因素,并且大部分模型都是数值模拟的。 The current perovskite solar cells models ignored some physical factors due to certain limitations，and most ofw hich were numerical simulations．
15742 因此,本文提出了一种考虑多种物理效应的钙钛矿太阳能电池的半解析模型,该模型基于解一个修正过的漂移扩散方程,使用费米-狄拉克分布研究载流子浓度；考虑了波长分布对入射光的影响,将光生载流子表示成关于坐标的函数；采用Pasveer等的迁移率模型μ(T,p,F),提出了一个统一的电场强度函数。 Therefore，in this article，we proposed a semi－analytical model for the perovskite solarcells based on multiple physical effects． The model is based on solving a modified drift－diffusion equation，w hich used Fermi－Dirac distribution to study the carrier concentration; the influence of wavelength distribution on incident light was taken intoconsideration，the photo generated carriers was expressed as a function of the coordinates． The mobility model of Pasveer μ( T，p，F) was used and a unified electric field intensity function was introduced．
