摘要
基于光电二极管的光致发电和电致发光特性可以实现光电-电光转换特性。因此,近年来各类半导体光电材料制成的太阳能电池(solarcell)和发光二极管(light-emitting diodes)吸引了人们的极大兴趣。然而现阶段的光电转换器件要求同时兼具低制造成本,高光伏表现和节能环保的特性。迫使科研人员寻找一种新的光伏材料满足上述要求。以甲基胺碘化铅(MAPbI3)为代表的金属卤化物钙钛矿(Perovskite)材料因具有生长工艺简单、光谱吸收范围宽和缺陷容忍度高等优点,是作为新型光电器件的理想材料。文中将对该种材料在两种光电器件中实现光电-电光转换的工作原理进行分析。
Based on the photoelectric generation and electroluminescence characteristics of photodiodes,the photoelectric to electro-optical conversion characteristics can be realized.Therefore,solar cells and light-emitting diodes being made by various semiconductor photoelectric materials have attracted great interest in recent years.However,the current photoelectric conversion devices require low manufacturing cost,high photovoltaic performance and energy saving and environmental protection characteristics.So a new photovoltaic material is needed to be found to meet the above requirements.Metal halide perovskite,represented by MAPbI3,is an ideal material for new optoelectronic devices because of its advantages such as simple growth process,wide spectral absorption range and high defect tolerance.The working principle of photoelectric to electro-optical conversion in two kinds of photoelectric devices is analyzed.
