From Lead Halide Perovskites to Lead‐Free Metal Halide Perovskites and Perovskite Derivatives
Advanced Materials, 2019 AbstractDespite the exciting progress on power conversion efficiencies, the commercialization of the emerging lead (Pb) halide perovskite solar cell technology still faces significant challenges, one of which is the inclusion of toxic Pb. Searching for Pb‐free perovskite solar cell absorbers is currently an attractive research direction. The approaches

Zwitterions in 3D Perovskites: Organosulfide-Halide Perovskites
Journal of the American Chemical Society, 2022 Although sulfide perovskites usually require high-temperature syntheses, we demonstrate that organosulfides can be used in the milder syntheses of halide perovskites. The zwitterionic organosulfide, cysteamine (CYS; +NH3(CH2)2S-), serves as both the X- site and A+ site in the ABX3 halide perovskites, yielding the first examples of 3D organosulfide ...
