Ultrathin polymethylmethacrylate interlayers boost performance of hybrid tin halide perovskite solar cells
Keyword(s):
Introducing a polymethylmethacrylate (PMMA) layer at the (PEA)0.2(FA)0.8SnI3 perovskite/hole transport layer interface leads to a remarkable improvement in the photogenerated current density and fill factor, resulting in an increase in the power conversion efficiency from 6.5% to 10%.
