Mismatch of Quasi–Fermi Level Splitting and Voc in Perovskite Solar Cells
Advanced Energy Materials, 2023 Perovskite solar cells have demonstrated low non‐radiative voltage losses and open‐circuit voltages (VOCs) that often match the internal voltage in the perovskite layer, i.e. the quasi‐Femi level splitting (QFLS).
