With the increasingly prominent energy and environmental issues, solar power generation as the backbone of the new energy industry has received a lot of attention. Among them, the development of solar cells is crucial for the entire photovoltaic industry. At present, the technology of crystalline silicon solar cells is mature, and it is the mainstream in the market, but there are problems such as high cost, efficiency bottleneck, etc; However, the overall efficiency of thin film solar cells is not ideal, and it is difficult to achieve mass production. In this case, it is urgent to develop new solar cells with rich raw material resources, non-toxic and environment-friendly, based on thin film technology and high conversion efficiency.

Among them, the new perovskite solar cell is a research hotspot in recent years. The perovskite solar cell is developed from the sensitized solar cell, which has the obvious advantages of cleaner, easier application, low manufacturing cost and high efficiency. Although the research of perovskite solar cells is in full swing, the problems faced are also worthy of attention. First of all, this new type of solar cell has stability problems in the assembly process, including the stability of materials and the stability of high-efficiency battery devices; Secondly, the organic-inorganic hybrid perovskite materials contain heavy metal lead, which is a highly toxic substance and seriously pollutes the environment; Finally, the morphology and crystallinity of the perovskite layer play a decisive role in the performance of the perovskite battery, and there are many factors affecting the properties of these materials, which need more research and exploration.
