This research focuses on enhancing the efficiency of wide bandgap lead halide perovskite solar cells (WBG Pb-PVK PSCs) using FA0.8Cs0.2PbI1.8Br1.2 as the light-harvesting layer. By passivating the hydrophobic surface of the hole transporting layer (PTAA) with a monomolecular layer, improved hydrophilicity and band alignment result in WBG Pb-PVK PSCs achieving an impressive 16.52% efficiency at 1.77 eV.
How Paios was used
MS curves, EIS, TPC, and TPV results were all performed using Paios from Fluxim
