[0002] With the continuous development of the economy, energy and environmental issues have become important constraints on economic development. Solar energy, as a clean energy source, has been widely researched and applied all over the world. The production of solar cells mainly uses inorganic non-metallic materials, such as all-inorganic Perovskite materials are very suitable as absorbing layer materials in solar cells, but the three-dimensional structure of this material is unstable and prone to phase transition, which is not conducive to light absorption, which limits its application in optical devices

[0003] At present, in order to improve the stability of this material, it is usually covered with hydrophobic organic matter on the surface of this material or doped with other elements inside it. However, these two methods cannot fundamentally solve the problem of low material stability. Although the method of covering the surface with organic matter can isolate the material from water and oxygen in the air, once the organic matter on the surface falls off or the coverage is insufficient, water and oxygen will invade into the material, thereby causing the material to undergo a phase change and reducing the material’s durability. Stability. In addition, doping other elements can improve the stability of the material, but it will increase its band gap and reduce its light absorption ability, which is not conducive to the application in solar cells, and the added elements are also prone to oxidation. On the contrary, it will reduce the overall stability of the material.
