The formation of high-density charge trap states alongthe surfaceand grain boundaries of the perovskite absorber is a major cause ofrecombination that limits the efficiency and quickly degrades thelong-term stability of perovskite solar cells (PSCs). To improve thePSC performance, we investigated the use of amino acids with Lewisacid-base functional groups, namely, 2-guanidinoacetic acid, l-aspartic acid, l-glutamic acid, and 3-guanidinoproponaicacid (3gpa), as passivating dopants for blade-coated perovskite films.The best photovoltaic performance was achieved with 4 mol% 3gpa doping,which effectively passivated both positively and negatively chargeddefects, resulting in a 12.9% improvement in the open-circuit voltageand a high PCE of 19.83%. Additionally, the improved carrier lifetimeand reduced defect density led to improved long-term stability inblade-coated PSCs.
