摘要

光提取是决定发光二极管效率的关键因素。根据射线光学模型，这在高折射率包晶发光二极管中变得更加明显。光子再循环和微腔效应是突破射线光学效率限制的重要途径。然而，这两种效应是相互竞争的，也就是说，优化这两种效应的策略是相互排斥的。要想在效率上有所突破，我们应该偏重其中一种效应，抑制另一种效应。

Competing light extraction strategies in perovskite light-emitting diodes

Light extraction is a key factor determining the efficiency of light-emitting diodes. This becomes more pronounced in high-refractive-index perovskite light-emitting diodes according to the ray-optics model. Photon recycling and microcavity effect are important ways to break through the ray-optics efficiency limit. However, these two effects are competing, that is, strategies to optimize them are mutually exclusive. For a breakthrough in efficiency, we should favour one of them and inhibit the other.
