fossil fuels are currently the most widely used fuel in the world, which makes the largest amount of elastic materials such as rubber lining in fixtures. The large-scale use of fossil fuels has brought great impact on the earth's environment, such as global warming and acid rain. Facing this severe situation, scientists all over the world have carried out research on renewable energy and green energy technology. Solar energy is widely studied as the most important renewable energy and green energy. As a solar energy conversion equipment, the elastic energy stored in the experimental machine module itself during the pressure process will be released. The improvement of its efficiency has aroused great interest of scientists. Solar energy is available all year round, providing 5.0% of energy every year × 1024j, which is 10000 times the actual annual energy consumption in the world. Part of the energy can be effectively used for power generation. However, due to the reflection of the air/glass interface and the accumulation of dust on the solar panel, most of the energy of the incident solar energy will be lost. Therefore, researchers from all over the world use multifunctional films or coatings to improve the shape and characteristics of the surface of solar panels, so as to enhance their self-cleaning, anti reflection, anti fog and energy transmission properties. In the preparation of solar panel coatings, a variety of materials and methods have been used, including superhydrophobic, superhydrophilic and photoactive coatings

this paper summarizes the preparation status and properties of solar panel coatings, including surface morphology, wettability, conductivity and light transmittance. Firstly, the basic concepts of self-cleaning (i.e. superhydrophobic, superhydrophilic) and antireflection (i.e. transparency) properties are discussed, and then the latest methods and technologies for preparing superhydrophobic, superhydrophilic, photoactive and transparent films are introduced. In the coating of solar panels, the application and research progress of self-cleaning, dust-proof and antireflection films in solar cell modules are emphatically introduced. Finally, advanced coatings with hybrid functions such as self-healing and antibacterial activity are introduced. This kind of coating presents a new progress in the coating of solar panels, because they combine a variety of properties such as sulfur dioxide and nitrogen oxide emissions, which can significantly improve the transparency, wettability, antifouling and self-cleaning of glass substrates with inaccurate speed control, and provide other functions such as self-healing and antibacterial activity
