Organo-lead-halide perovskites are promising materials for optoelectronic applications. Perovskite solar cells have reached power conversion efficiencies of over 22%, and perovskite light-emitting diodes have recently achieved over 11% external quantum efficiency. To date, most research on perovskite light-emitting diodes has focused on solution-processed films. There are many advantages of a vapor-based growth process to prepare perovskites, including ease of patterning, ability to batch process, and material compatibility. We investigated an all-vapor perovskite growth process by chemical vapor deposition and demonstrated luminance up to 560 cd/m.
有机铅卤化物钙钛矿是用于光电子应用的有前途的材料。钙钛矿太阳能电池的功率转换效率已超过22%，并且钙钛矿发光二极管最近已实现超过11%的外量子效率。迄今为止，大多数关于钙钛矿发光二极管的研究都集中在溶液处理的薄膜上。基于气相的钙钛矿生长工艺有许多优点，包括易于图案化、批量处理能力和材料兼容性。我们通过化学气相沉积研究了全气相钙钛矿生长工艺，并证明了高达560 cd/m的亮度。
