Saturation of Open‐Circuit Voltage at Higher Light Intensity Caused by Interfacial Defects and Nonradiative Recombination Losses in Perovskite Solar Cells

Abstract A new analytical expression that directly relates the open‐circuit voltage (Voc) in perovskite solar cells (PSCs) to the quasi‐Fermi level splitting (QFLS), interface energy offsets, and nonradiative recombination losses has been derived. It is found that the QFLS of the active layer plays...
