有机-无机卤化物钙钛矿（OHP）已被广泛研究用于具有超过22%的高转换效率的太阳能电池中。OHP独特的电学和光学性质使其在光电子器件应用中的应用超出了光电子学，如发光二极管、光电探测器、晶体管。新的信息存储技术和计算体系结构正在被广泛研究，目的是解决日益增长的接近摩尔定律和冯诺依曼瓶颈的挑战。忆阻器作为第四种基本电路元件，在信息存储和神经形态计算应用中具有强大的功能。近年来，羟基磷灰石作为一种有前途的忆阻材料受到越来越多的关注。特别是，它们的混合离子电子传导能力与光敏性相结合，为OHP提供了展示新功能的机会，如光学擦除记忆，光遗传学启发的突触功能和光加速学习能力。本文综述了基于OHP的忆阻器开发的最新进展，包括忆阻机制和分析模型，用于记忆和神经形态计算应用的通用忆阻特性，以及新型多功能化。最后讨论了基于OHP的忆阻器的挑战和未来前景。
Organic‐inorganic halide perovskites (OHPs) have been intensively studied for application in solar cells with high conversion efficiency exceeding 22%. The unique electrical and optical properties of OHPs have led to their use in optoelectronic device applications beyond photovoltaics, such as light‐emitting diodes, photodetectors, transistors. New information storage technologies and computing architectures are being researched extensively with the aim of addressing the growing challenge of approaching end of Moore's law and von Neumann bottleneck. As the fourth basic circuit element, memristor is a leading candidate with powerful capabilities in information storage and neuromorphic computing applications. Recently, OHPs have received growing attention as promising materials for memristors. In particular, their mixed ionic‐electronic conduction ability paired with light sensitivity provide OHPs with the opportunity to display novel functions such as optical‐erase memory, optogenetics‐inspired synaptic functions, and light‐accelerated learning capability. This review covers recent advances in OHP‐based memristors development including memristive mechanism and analytical models, universal memristive characteristics for memory and neuromorphic computing applications, and novel multi‐functionalization. Challenges and future prospects of OHP‐based memristors are also discussed.
