Abstract Stable perovskites light sources with long‐term stability are of great significance for future commercial applications. In this review, recent advances the degradation models and strategies enhancing corresponding summarized. Improving quality perovskite materials is a common way developing stable sources. For strengthening light‐emitting diodes, approaches such as surface interface engineering employing more hole injection layers effective. To enhance amplified spontaneous emission lasers, methods protecting by high intrinsic thermal conductivity stability, better managements, reducing threshold carrier densities useful. This work will be helpful further prompting performances, especially in fantastic field.
