ABSTRACT

Energy resource usage has been observed as the most important and on-going issue of the present world. Solar energy is considered one of the propitious forms of renewable energy, due to the amount of solar irradiation available for its generation, and is the most feasible way out of energy trouble in the entire world. Photovoltaic and solar thermal systems are parts of solar energy, which can effectively be utilized. A number of solar panels spread over a large area produce clean green power. High-efficiency solar panel requires high absorption of incident light. Antireflection coating on solar panels improves efficiency by reducing the reflection. Materials like glass have the amazing property of transparency, but an immense amount of light is reflected from the surface and reduces the sight through the material. Inspired by the observation of Lord Rayleigh, modification of surfaces with a thin layer of antireflection coating is widely used and applied for better transmittance by reducing reflection. To sustain the effectiveness, such as efficiency, cleanliness of the solar panel is important. Cleaning of solar panels by manpower was difficult and time-consuming. This can be solved by multifunctional antireflection (AR) cover glasses. In this work, the major goal is to give an inclusive plan about the antireflection coating by reviewing some of the previous works and make a comparison of those results with our work on silica-based AR coating.
