Recently, metal halide perovskite materials have attracted great interest in both photovoltaic and electroluminescent devices. The external quantum efficiency of the perovskite light-emitting diodes (pero-LEDs) has grown to over 20% within four years, and the operational lifetime has been improved to tens of hours. These achievements make pero-LEDs very promising technology in solid lighting and displays. In this Perspective, we first give a general introduction of the pero-LEDs; we then discuss various pero-LEDs with different cell configurations and perovskite emitting structures; to conclude, we propose some efficiency improvement strategies and development opportunities of pero-LEDs. Provided that we can continually improve efficiency and operational lifetime of pero-LEDs, we can make them more and more compatible with other mature technologies, like organic LEDs and inorganic LEDs, and then finally realize their practical application in daily life.

钙钛矿型发光二极管的兴起

近来，金属卤化物钙钛矿材料在光伏和电致发光器件中都引起了极大的兴趣。钙钛矿发光二极管（pero-LED）的外部量子效率在四年内已增长到20％以上，并且工作寿命已提高到数十小时。这些成就使pero-LED在固态照明和显示器中成为非常有前途的技术。在此透视图中，我们首先对pero-LED进行了概述。然后，我们讨论具有不同单元配置和钙钛矿发射结构的各种pero-LED；总而言之，我们提出了一些效率提高策略和pero-LED的发展机会。只要我们能够不断提高pero-LED的效率和使用寿命，
