  • Hybrid perovskites are a promising class of materials for photovoltaic applications. Here, addressing the need for high-quality hybrid perovskite materials, the authors achieve the rapid growth of hybrid perovskite single crystals of high quality by inverse temperature crystallization.

  • Visual evidence for photo-induced ionic migration in perovskite films without contacts is lacking. Here, the authors use a unique combination of confocal photoluminescence microscopy and chemical imaging to correlate the local changes in photophysics with composition in CH3NH3PbI3films under illumination.

  • Lead halide perovskites are developed for a number of optoelectronic applications. Here, Cho et al. use a thermal gradient to achieve directional crystallization of methyl ammonium lead iodide films. The periodic microarrays exhibit anisotropic charge transport properties.

  • An imbalance in I/Pb stoichiometry is thought to lead to defects in metal halide films. Here, Zhang et al. show that the addition of hypophosphorous acid in the precursor solution can significantly improve the film quality and enhance the photoluminescence intensity, leading to improved photovoltaic devices.
