Wafer-scale single-crystal perovskite patterned thin films based on geometrically-confined lateral crystal growth

Abstract

Wafer-scale deposition of uniform metal halide perovskite single-crystals is a step towards commercialisation. Using geometrically-confined lateral crystal growth, Leeet al., report patterned thin films of highly-aligned single-crystals and achieve lateral solar cells with efficiencies up to 4.83%.
