Tracking Photo-Induced Halide Segregation in Mixed-Halide Perovskite Solar Cells

Abstract: Organic-inorganic perovskite semiconductors are a promising new material in the world of solar cell technology. Though these materials show promising photo conversion efficiencies (over 29% in perovskite-silicon tandem cells), they present numerous difficulties when facing real-world application. In mixed-halide perovskites, a phenomenon known as halide segregation occurs upon photoexcitation of the material, which can … Read more
