Turkey and Albania are located in an advantageous position in the southern part of Europe in terms of solar energy. Both countries can receive solar light with a high intensity (~1500 kWh/m2) when compared with most of the European countries. However, the installed photovoltaic (PV) capacity corresponds respectively to 5 GW for Turkey and 10 MW for Albania which is low compared to the European countries. The installed PV capacities of both countries can only cover 2.5% of Turkey’s electricity needs and 1% of Albania’s electricity needs. In addition, both countries meet the majority of their energy needs from foreign countries, which means that both countries need to increase the installed capacity of the PV systems and maintain the efficiency of the existing PV systems to be able to benefit more from the sunlight. The buildup of pollutants and contaminants on the glass covering of solar cells has a detrimental impact on the performance of PV systems, ultimately diminishing their efficiency. Our research work presents the development of self-cleaning coatings designed for PV systems that aims to mitigate the efficiency losses caused by contamination in existing PV systems across both countries. The composite materials SiO2/WO3 and SiO2/WO3/ZnO were developed and applied onto glass substrates via a dip-coating methodology using solutions prepared from their respective compositions. The results have shown that solar cell coated with the SiO2/WO3/ZnO film offered nearly equivalent solar cell efficiency levels compared to those of uncoated solar cells.
