The Effect of Deep Defects on the Efficiency Variation of CH₃NH₃PbI₃ Perovskite Solar Cells

Divalent organic cations as a novel protective layer for perovskite materials

“…This shows that the modification has a small disadvantageous effect on the photoelectric performance while increasing the stability of the PSCs. The PCE of a similar sandwiched model MAPbI 3 simulated by Adihetty et al 56 is about 22.3%, which is a little bit lower than our result. The difference may be caused by the different settings of parameters.…”

“…To compare with the experimental results more conveniently and have a better understanding of whether the modification with ProDMA would influence the performance of the perovskite solar cells (PSCs), the PCE and some other photoelectric properties of model structures were simulated by Solar Cell Capacitance Simulator (SCAPS-1D) software. 55 To make the simulation similar to the actual experiments, 56 the sandwiched perovskite-based solar cells PS/MAPbI 3 /PS (PS = the original perovskite, (MA) 2 -PS, or the modified one, ProDMA-PS) are taken as the light harvesters. TiO 2 and Spiro-OMeTAD are employed as the electron transport material (ETM) and hole transport material (HTM), respectively.…”
