Pyramid‐Shaped Perovskite Single‐Crystal Growth and Application for High‐Performance Photodetector (Advanced Optical Materials 25/2024)

Pyramid-Shaped Perovskite Single Crystals Pyramid-shaped perovskite single crystals are constructed with an asymmetrically spatial confinement-induced crystallization method. The crystals exhibit high quality and enhanced absorption capability. A constructed photodetector shows unique advantages, including high performance, flexibility, and insensitivity to the incident photon direction. In this research (see article number 2400329), Gang Ouyang, Wei Hu, Jianfa Zhang, and co-workers provide a promising approach for the development of tandem solar cells and other optoelectronic devices.
