CH3NH3PBX3（MAPBX（3）） - 基于钙钛矿在过去几年中吸引了巨大的研究工作。 With the discovery that the HC(NH2) 2PbI3 (FAPbI(3)) perovskite offers even higher solar cell efficiency, better thermal stability, and broader optical absorption, it is expected that it will provide more excitement in optoelectronic applications including laser, LED,光电探测器等。提出了使用逆温度的反应性结晶过程和相关的晶状理切片过程，制备大型单晶甲米型膜 - 栖息地FAPBI（3）的发展。大型单晶甲氨基植物晶片晶片的可用性使得可以制造集成的电路。设计和制备了一块细晶片上的153个光电探测器，表明钙钛矿晶圆上集成电路的质量生产可行性。发现基于晶片的光电探测器表现出优异的性能，其光响应比其薄膜钙钛矿的光吸收高90倍。
CH3NH3PbX3 (MAPbX(3))-based perovskite has attracted tremendous research efforts in the last few years. With the discovery that the HC(NH2) 2PbI3 (FAPbI(3)) perovskite offers even higher solar cell efficiency, better thermal stability, and broader optical absorption, it is expected that it will provide more excitement in optoelectronic applications including laser, LED, photodetector, etc. The development in preparing large Single-Crystalline Formamidinium-Perovskite FAPbI(3) using the inverse-temperature reactive crystallization process, and associated wafer-slicing process is presented. The availability of the large Single-Crystalline Formamidinium-Perovskite Wafer makes it possible to fabricate integrated circuits. An array of 153 photodetectors on a piece of thin wafer, demonstrating feasibility of mass production of integrated circuits on the perovskite wafer is designed and prepared. It is found that the wafer-based photodetector shows much superior performance, with 90 times higher photoresponse and broader optical absorption than its thin-film perovskite counterpart.
