高性能自清洁涂层构筑及太阳能电池板防污机制探讨OA

To solve the problems of reduced power generation efficiency,shortened life and high cleaning costs caused by surface pollution of solar cells,a self-cleaning coating with high light transmittance,durability and environmental protection has been developed.With modified nano SiO2 as the core,two super-hydrophilic and super-hydrophobic coatings were prepared by nanosynthesis and sol-gel methods,and the process was optimized.After performance testing and application verification in 10 MW photovoltaic power stations,the anti-fouling mechanism was discussed.The results show that the light transmission rate of the super-hydrophilic coating is 95.8%,the rain dust removal rate is 92.3%,the light transmission rate of the super-hydrophobic coating is 95.2%,and the water dust removal rate is 87.6%.The outdoor life of the two coatings exceeds 3 years,the light transmission rate drops by≤3%,and it is non-toxic and environmentally friendly.After application,the battery panel cleaning cost is reduced by 71.2%,and the power generation efficiency is increased by 6.8%.The coating achieves the synergy of high light transmission and efficient self-cleaning.Anti-fouling results from the synergistic effect of interface wettability control and microstructure.It has good durability and economy,and has significant engineering application value.
