The recent reaching of 20% of conversion efficiency by solar cells based on metal hybrid perovskites (MHP), e.g., the methylammonium (MA) lead iodide, CH3NH3PbI3 (MAPbI3), has excited the scientific community devoted to the photovoltaic materials. Howeve
The utmost reason behind the enhanced stability of quasi 2D metal halide perovskites is attributed to the hydrophobic organic side chains which resists interaction of moisture with MA (soluble in H2O) which further helps in maintaining the layered structure30,34, as well as the van der Waals ...
研究结果表明,MAPbI 3 PDs由于具有光电-热电双模工作机制,可以实现覆盖UV至THz范围的超宽带光电探测,其高响应度分别达到10 5 mA W -1 和10 2 mA W -1 。此外,使用1064 nm脉冲激光测量了76 ns的快速响应时间。这项工作为钙钛矿型热电探测器的发展打开了一扇门,并证明MAPBI 3 是一种很有前途的超宽带PD材料...
Their remarkable properties are underpinned by atomic struc- tures of hybrid perovskites7, ABX3, with organic species such as CH3NH3+ (MA+) and CH(NH2)2+ (FA+) occupying A-site and inorganic Pb2+ in B-site surrounded by X-octahedron formed by halogen elements like I− and Br−. ...
