The background of photovoltaic self-cleaning technology: Since the beginning of this century, the photoelectric conversion technology has developed rapidly. After the rapid improvement of photoelectric conversion efficiency, the research and development speed of breakthrough technology has entered a stable period as it has gradually approached the theoretical limit value. In this case, the influence of other factors on the power generation efficiency and power generation of the components is gradually becoming prominent. Among them, the influence of dust occlusion on components has gradually become an important research topic.

Self-cleaning technology refers to the technology of self-cleaning and cleaning ability. The research of this technology was first carried out in the 1970s and 1980s, usually using glass, ceramic tiles, cement and other building materials as carriers. In the field of photovoltaics, the self-cleaning technology is mainly used on the surface of glass panels for photovoltaic modules, so that the glass undergoes physical or chemical reaction, so that it is no longer necessary to pass the traditional manual scrubbing method, and the clean state is achieved under the flushing of natural rainwater. The self-cleaning technology carrier is a photovoltaic module glass panel, and the dust-proof self-cleaning material is combined with the glass in a state of "film layer" or "coating" to exhibit a self-cleaning effect. The glass industry with this self-cleaning capability is called "self-cleaning glass", and the component that installs this glass is a "self-cleaning component." Self-cleaning technology is mainly classified into super-hydrophilic self-cleaning glass and super-hydrophobic self-cleaning glass according to its invasiveness.

       We have found that self-cleaning technology for photovoltaic modules has also been introduced in the market. Due to process defects, the film layer will be ineffective in a short period of time. Some of the film layers have poor adhesion to the glass substrate, which not only loses self-cleaning ability, but also Seriously, it affects the power generation capacity of photovoltaic modules. In fact, the performance and reliability of the self-cleaning glass layer is closely related to the superhydrophobic coating material and its manufacturing process.

      Shangmeng Technology pays attention to the surface treatment technology of solar photovoltaic panels. Its main functions include: anti-reflection, infrared absorption (cooling), self-cleaning, dustproof and snowproof. Develop different products using different technologies for different climatic conditions. The current main products are: super-hydrophobic dust-proof self-cleaning nano-coatings (Northwest) and super-hydrophilic self-cleaning coatings (mainly in the south and rainy areas).
