摘　　要：量子剪裁发光是20世纪50年代由Dexter提出的,吸收一个高频光子转换为两个低频光子的过程。20世纪90年代提出了将Yb^(3+)离子的剪裁发光应用于提高硅基电池效率的构想,但是一直没有实质性的进展。2017年,Yb^(3+)离子的铅卤化物钙钛矿量子剪裁发光材料被发现,并大幅提高了商用硅电池的光电转换效率,为光伏应用带来新的契机。本文简单梳理量子剪裁发光材料发展的历程、新兴Yb^(3+)掺杂钙钛矿材料发现的过程、光学性能与发光机制、应用探索以及给光伏产业带来的潜在影响。同时,也提出了未来商用化进程中需要解决的一些关键问题和努力方向。Quantum cutting emission is a process of absorbing one higher frequency photon,and emitting two lower frequency photons,which was first presented by Dexter in 90th of last century.The assumption of applying Yb^(3+)quantum cuttingemission to c-Si solar cells was designed,but no essential development was reported.In 2017,CsPb(BrCl)_(3):Yb^(3+)quantum cutting phosphors were discovered,which largely boosted the power conver⁃sion efficiency of commercial c-Si solar cells,and brought about new opportunity for photovoltaic application.In this article,we simply sum up the developing process of quantum cutting phosphors,the discovery process of novel CsPb(BrCl)_(3):Yb^(3+),its optical properties and luminescent mechanisms,applying explosion and the poten⁃tial influence on photovoltaic industry.At the same time,we also list some important problems to be resolved in the future for practical applications.
