Overview
Metal halide perovskites have emerged at the forefront of next-generation, thin-film semiconductors for photovoltaic and light-emitting applications. These materials exhibit remarkable optoelectronic properties such as long charge carrier diffusion lengths and high radiative emission efficiencies, which are unexpected for low-temperature, solution-processed semiconductors. Despite impressive technological advancements in device efficiency, a fundamental understanding of perovskite photophysics and photochemistry is still lagging behind. Photoluminescence, cathodoluminescence, and electroluminescence have emerged as informative tools capable of probing recombination, charge carrier transport, and defect migration in these materials. Furthermore, adding high spatial resolution to the luminescence methods by their combination with microscopy have revealed local variations in optoelectronic quality, which have been further linked to differences in material composition, nanostructure, and defect density.
This special issue will focus on both steady-state and transient measurements of perovskite luminescence both on the micro and macroscale, with the specific goal to connect luminescence properties with material composition and structure, defect formation and annihilation, and charge carrier trapping and transport. We encourage the submission of novel, intriguing and unexplained observations related to the unique luminescence properties of perovskites.
