Due to the low formation enthalpy and high defect tolerance, in situ fabricated perovskite quantum dots offer advantages such as easy fabrication and superior optical properties. This paper reviews the methodologies, functional materials of in situ fabricated perovskite quantum dots, including polymer nanocomposites, quantum dots doped glasses, mesoporous nanocomposites, quantum dots-embedded single crystals, and electroluminescent films. This study further highlights the industrial breakthroughs of in situ fabricated perovskite quantum dots, especially the scale-up fabrication and stability enhancement. Finally, the fundamental challenges in developing perovskite quantum dots for industrial applications are discussed, with a focus on photoinduced degradation under high-intensity light irradiation, ion migration under electrical bias and thermal quenching at high temperature.
