Amidino-Based Ligand Enables High-Performance MA-Free Perovskites Solar Cells
Despite remarkable progress in formamidinium-cesium perovskites solar cells, the detrimental defects within the films hinder their power conversion efficiency (PCE) towards the Shockley-Queisser limit. Here, we propose a ligand engineering by introducing an additive, namely morpholine-4-carboximidamide hydrochloride, achieving a remarkable PCE of 24.01%.
