SELF CLEANING THIN FILM NANO-COATING FOR SOLAR PANEL GLASS

Abstract

Researchers studied the effect of dust cleaning on Photovoltaic (PV) glass and its efficiency with time factor and the presence of dust on these PV panels leads to medium reduction yield up to 16% across the first-year. The aim is to investigate the application of self-cleaning by using different coatings such as titanium dioxide as thin film and silica pre-coated with titanium dioxide to improve the PV system and put alternatives using manual cleaning, with no lose in the effectiveness in maintenance yield. This achieves some of the goals of the 2030Agenda for sustainable development adopted by United Nation in 2015; throw this research we touch on the health and energy goals. A set of experiments was done on laboratory scale by using the two coating layer and the results showed that using silica pre-coated with titanium dioxide on PV panels are more effective than using titanium dioxide layer only because of many reasons as there is no cracked layer, increasing in photo catalytic activity and also the stability of the coated layer is very high. And when measure these coating layer on a real PV panel with and without the coating we observed that the energy is improving and the coated panel can save energy up to 2.5%.
