Synergistic improvements in the performance and stability of inverted planar MAPbI3-based perovskite solar cells incorporating benzylammonium halide salt additives

Three different benzylammonium halide (Cl, Br, and I) salts were investigated to elucidate their effects as additives on MAPbI₃ perovskite surface morphology, crystal structure, optical properties, and solar cell performance and stability.
