High-strain actuation of lead-free perovskites : compositional effects, phenomenology and mechanism
… has been mapped by means of a Landau type free energy expansion. A nanodomain relaxation mechanism of frequency dependent electromechanical response of BNBZT has been suggested and is supported by optical and transmission electron microscopy.

Single-step, Atmospheric Pressure Chemical Vapor Deposition of Methylammonium Bismuth Iodide Thin Films
<p>Lead halide perovskites (CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> and its variants) are promising solar cell absorber materials. Though the reported power conversion efficiencies of lead halide perovskite solar cells (up to 21%) are competitive with commercial silicon solar cells, lead …
