Effect of Photocatalytic Coating on Concentrator Photovoltaic Module

Abstract:

The anti-soiling layer was coated on the surface of Fresnel lens for concentrator photovoltaic. The anti-soiling layer was prepared by coating the acrylic urethane capping layer, the inorganic/organic nanograded intermediate layer, and the photocatalytic surface layer including modified WO₃ and partial hydrolyzed tetraethyl orthosilicate. The adherent sand for the sample without coating was 0.023 g and that for the sample with coating was 0.008 g. The adhesion of sand was suppressed owing to the effect of the anti-soiling coating. The electrostatic potential for the sample without coating was 0.23 kV, and the value was much higher than that for the sample with coating. The electrostatic charge at the surface of sample was suppressed with the anti-soiling coating.
