Abstract / Full Text

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.
