To date, many research efforts factors to high performance optoelectronic devices, such as have been made to enlarge grains of the perovskite polycrys- [15–19] solar cells, ultrafast photodetectors, field effect transistors, light- talline films for reducing the total GB area; for example, emitting diodes, among others. Suppressing these trap states large-aspect-ratio (up to 7.9) polycrystalline perovskite grains [15] in semiconductor thin films through a simple and efficient have been grown on a nonwetting surface, resulting in over approach is thus critical to the enhancement of optoelectronic tenfold reduced charge recombination in the devices. Now that device performance. A new generation of photovoltaic mate- photogenerated carriers
