چکیده
Photovoltaic (PV) is a method of generating electrical power by converting solar radiation into direct current electricity . Because it is safe, renewable and pollution-free, PV has advanced considerably in recent years in large scale. These installations usually are located in sun-drenched desert areas where dry weather and winds sweep dust into the air and deposit it onto the surface of solar panel. Because of this problems Cleaning them is very important to maintain their performance [1,2]. If the surfaces of the solar cell array were covered with a pellucid self-cleaning nano-film, it will keep clean. The self-cleaning nano-film can make of super-hydrophobic materials. Superhydrophobic surfaces such as the leaves of the lotus plant show high hydrophobicity and extremely low wettability. The nanostructures of this surface can enhance the contact angle (CA) to higher than 150, so the water droplets that hit the surface would quickly roll off, carrying dust and other particles with them [3-5]. Also when the catalysts that possess a hydrophobic surface and when they have the appropriate surface nanostructure and microstructure, they become superhydrophobic. To obtain of this goal we synthesized mesopours templated TiO2 on glass and PDMS layers coated to titanium dioxide (TiO2) surfaces to investigate of the photocatalytic activity. In the other words, we synthesized a superhydrophobic brush like photocatalytic TiO2 by grafting polydimethylsiloxane into the pores of catalyst. The photocatalytic activity is enhanced for the superhydrophobic TiO2 with a PDMS layer comparing with bare TiO2. Our work will be helpful to develop guidelines for modifying catalyst surfaces with hydrophobic properties and simultaneously maintain high catalytic activity for self-cleaning in solar panels.کليدواژه ها
