Review by Wang Jianpu & Huang Wei from Nanjing University of Technology: Tin Halide Perovskite Light Emitting Diodes
In recent years, tin halide PeLEDs have made significant breakthroughs in device efficiency, spectral tunability, and long-term operational stability. However, the easy oxidation of Sn²⁺ and rapid crystallization kinetics severely restrict their further development. The oxidation of Sn²⁺ and the rapid crystallization of the perovskite layer can lead to p-type doping characteristics and high defect … Read more
