Abstract

Based on the reaction of electron-hole separation in perovskite solar cells, we derived the mathematical relationship between current and voltage from the viewpoint of electrochemical kinetics and, moreover, by using this relation, we successfully fitted the i–E curves. We found that the nonlinear relationships between the activation energy and the potential of the recombination reaction are the fundamental reason for the appearance of the hysteresis loop.

钙钛矿太阳能电池电化学动力学理论：拟合电流-电压曲线

摘要

基于钙钛矿型太阳能电池中电子-空穴分离的反应，我们从电化学动力学的角度推导了电流和电压之间的数学关系，此外，利用这种关系，我们成功地拟合了i–E曲线。我们发现活化能与重组反应电位之间的非线性关系是出现磁滞回线的根本原因。
