In recent years, organic perovskite quantum dot semiconductors have become an integral part of the solar field and planar light-emitting devices, and they are also indispensable. The high-efficiency perovskite quantum dots have also attracted widespread attention, and have also attracted attention in many photovoltaic fields. The important application space therefore makes the material difficult to obtain and expensive. This paper proposes the use of recycled recycling of environmental protection issues, the use of lead scraped lead batteries as the material for the production of perovskite quantum dots, and its material properties for further research and analysis. The recovery of the perovskite quantum dot CsPbBr3 was performed by recovering lead scrap from lead storage batteries. The characteristics of CsPbBr3 were analyzed using different ratios. The scanning electron microscope was used to observe the surface morphology and cross section of the film. The structure and PL optical excitation spectrum measurement system were used to analyze the optical properties. Finally, the analysis situation and influence of the dispersion solution were further discussed, and the influence and results of the recovery of the lead scrap from the lead battery to produce the perovskite quantum dot were thoroughly studied. The results show that the use of lead scrap from lead-acid batteries as a material for the production of perovskite quantum dots, CsPbBr3, can be successfully synthesized. It not only saves material, but also proves that recycling is valuable, and it is helpful for future shortages of materials and materials not easily accessible to achieve a major advantage in the future, although the efficiency is not very high, it will be purified using recycled lead in the future to achieve higher efficiency.
