Abstract
α-FA 1-x Cs x PbI 3 is a promising absorbent material for efficient and stable perovskite solar cells (PSCs) 1,2 . However, the most efficient α-FA 1-x Cs x PbI 3 PSCs require the inclusion of the additive methylammonium chloride 3,4 , which generates volatile organic residues (methylammonium) that limit device stability at elevated temperatures 5 . Previously, the highest certified power-conversion efficiency of α-FA 1-x Cs x PbI 3 PSCs without methylammonium chloride was only approximately 24% (refs. 6,7 ), and these PSCs have yet to exhibit any stability advantages. Here we identify interfacial contact loss caused by the accumulation of Cs + in conventional α-FA 1-x Cs x PbI 3 PSCs, which deteriorates device performance and stability. Through…
