    Influencing the performance of a Building Integrated low-Concentration Photovoltaic (BICPV) system by adapting an Anti-Reflective Coating (ARC) with a pyramidal texture
    (Universidad EAFIT, 2021) Bernal del Río, Santiago; Osorio Gómez, Gilberto
    The generation of electric energy from photovoltaic solar energy brings a new opportunity to reduce generation costs, in addition to reducing the emission of greenhouse gases. This type of generation has positioned itself as the most important for renewable energies, especially because of the impact it has had on generation on an industrial scale. However, in the residential sector, different strategies are proposed within the framework of the best use of the available area in order to reduce costs, as is the case of low-concentration photovoltaic concentration systems. This document proposes the development of an Anti-Reflective Coating (ARC) with a pyramidal texture in two dimensions for a V-Trough type photovoltaic concentrator, specifically for a Building Integrated low-Concentration Photovoltaic (BICPV), with the aim of increasing the light capture of these systems due to the loss caused by the rays coming from incidence angles different from the normal surface. For this, a methodology is executed where the concentrator is designed, the material for the Anti-Reflective Coating is determined, the design of the geometry of the texture, and, later, simulations are carried out by means of ray tracing, and experimental validation, where finally data is taken in real time of the generation of the CPV with the texture, and, it is checked how the application of this texture affects in a positive way the generation of the photovoltaic system, with increases of more than 3% in the normalized efficiency.
