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.

钙钛矿发光二极管中的竞争性光提取策略

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，这在高折射率钙钛矿发光二极管中变得更加明显。光子回收和微腔效应是突破射线光学效率极限的重要途径。但是，这两种效果是相互竞争的，也就是说，优化它们的策略是相互排斥的。为了提高效率，我们应该偏爱其中一种，抑制另一种。
