Innovative Thermophotovoltaic Hybrid Resin Tile

The product developed and here presented is the result of a widespread research project related to hybrid thermophotovoltaic panels. Starting from the numerical analysis, experimental testing and relative optimization of different hybrid solutions, we moved on final prototyping of an innovative thermophotovoltaic bi-resin walkable tile suitable for covering different kinds of surfaces subjected to solar radiation. The tile is made up of a layer of photovoltaic cells placed in contact, by means of a thermoconductive paste, with an aluminum alloy heat sink which transfers the heat from the cells to the water flow. The bottom of the heat sink and the hydraulic and electrical connectors are encapsulated in an opaque insulated resin. The top and the cells are covered with a transparent resin. This solution is suitable for any flat surface exposed to solar irradiance (often not usable and / or unused from an energy point of view) allowing a double energy output (thermal and electric) and a guaranteed walkability 365 days a year.
