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