Preparation and performance of super hydrophilic and antistatic self-cleaning coating for solar photovoltaic panels
Against the background of global climate change and the increasing depletion of fossil energy,the development and utilization of solar energy is receiving increasing attention from the international community.However,solar panels are mostly used outdoors,where the deposition of dust and other particulates in the natural environment easily occurs,which has become an important factor affecting the photoelectric conver-sion efficiency of photovoltaic components.Herein,SiO2 nanoparticles were prepared by sol-gel method,and a superhydrophilic,anti-static self-cleaning coating(HAC)was further prepared.Based on this,the effect of SiO2 nanoparticle size and content on the surface micro-nanostructure of the coating was investigated,elucidat-ing the relationship between SiO2 nanoparticle sol-gel and the wettability of the self-cleaning coating.The self-cleaning coating prepared in this study possesses both excellent superhydrophilic and anti-static properties,ef-fectively enhancing the dust and dirt resistance of the photovoltaic glass surface.At the same time,HAC can also increase the transmittance of sunlight to a certain extent,so as to further improve the efficiency of power generation,demonstrating significant potential in enhancing the anti-soiling self-cleaning ability and power gen-eration of photovoltaic components.
