With the developmentof PV systems’ technology over the years and the reduction of production costs,PV systems are now being used for electricity generation. PV systems are listedamong the renewable energy sources as the only requirement is solar energy and electricitygeneration is carried out without any fuel and waste. Solar cells used in PVsystems are adversely affected by extremes of temperature, shading, reflection,and pollution. It is known that before sunrays reach the cell’s surface, someof them disappears from the protective glass surface and are reflected backfrom the cell through the glass surface. Anti-reflection coatings (ARC) areused to reduce the energy loss and increase solar cell efficiency and outputpower. SiO2 and MgF2 are the most commonly used solutionsamong these coatings. It has been seen that the most efficient applications,with anti-reflection coatings as single, double, triple and more layers, are intriple layers applications. It has been observed that applications to the protectiveglass surface have self-cleaning properties, and TiO2 and ZrO2are frequently used for this. The reflectance index of the protective glass,which is normally 1.51, can be reduced to 1.20 in silicone cells and 1.28 inthin film surfaces with the AR coatings.
