Utilization of Nano thin films for solar cell self-cleaning

The present work for preparing titanium dioxide as thin film to improve the PV system and put alternatives to manual cleaning with no loss in the efficiency. Using self-cleaning coatings instead of cleaning chemicals on PV panels is a very suitable process in the application and cost. A set of experiments were conducted on a laboratory scale by using the coating layer. The results showed that using pre-coated with titanium dioxide on PV panels is more effective than no coating layer. As increasing photo catalytic activity and the stability of the coated layer are more effective.
