Photoflexoelectric effect in halide perovskites [PDF]

Nature Materials, 2020
Harvesting environmental energy to generate electricity is a key scientific and technological endeavour of our time. Photovoltaic conversion and electromechanical transduction are two common energy-harvesting mechanisms based on, respectively, semiconducting junctions and piezoelectric insulators. However, the different material families on which these

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 ...

Biotoxicity of Halide Perovskites in Mice

Advanced Materials, 2023
AbstractHalide perovskites are crystalline semiconductors with exceptional optoelectronic properties, rapidly developing toward large‐scale applications. Lead (II) (Pb2+) is the core element used to prepare halide perovskites. Pb2+ can displace key 2+ elements, including calcium, zinc and iron, that regulate vital physiological functions.
