Comprehensive study of anomalous hysteresis behavior in perovskite-based solar cells.

ABSTRACT: Perovskite solar cells (PSCs) have shown remarkable progress with the rapid increase in power conversion efficiency to reach 25.7% over the last few years. However, it is difficult to precisely determine the energy conversion efficiency for PSC, because of anomalous current density-voltage (J-V) hysteresis. Normal J-V hysteresis has been reported in many papers, where the backward scan performance is higher than the forward scan one. In this work, using Drift-Diffusion Modeling, normal hysteretic behavior associated with ion migration with different scanning rates, pre-bias voltages, and charge-carrier mobility is studied. In addition, the inverted J-V hysteresis by modification of the simulation model, where anions and cations flux towards the transport layers and are accumulated simultan
