“…GIGS cell efficiency which is normally %16.7 increased to 17.6% with a single layer coating. MgF2 was used at a thickness of about 120 nm [15]. In the case of investigating other thin film types, the efficiency was increased from 1.31% to 1.65% after coating and a total increase of 20.60% was obtained.…”

With the development of PV systems' technology over the years and the reduction of production costs, PV systems are now being used for electricity generation. PV systems are listed among the renewable energy sources as the only requirement is solar energy and electricity generation is carried out without any fuel and waste. Solar cells used in PV systems are adversely affected by extremes of temperature, shading, reflection, and pollution. It is known that before sunrays reach the cell's surface, some of them disappears from the protective glass surface and are reflected back from the cell through the glass surface. Antireflection coatings (ARC) are used to reduce the energy loss and increase solar cell efficiency and output power. SiO2 and MgF2 are the most commonly used solutions among these coatings. It has been seen that the most efficient applications, with anti-reflection coatings as single, double, triple and more layers, are in triple layers applications. It has been observed that applications to the protective glass surface have self-cleaning properties, and TiO2 and ZrO2 are 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 in thin film surfaces with the AR coatings.
