Abstract: Hybrid concentrated photovoltaic device comprising: (i) at least one luminescent solar concentrator (LSC) having the shape of a polygonal, circular, or elliptical plate, comprising at least one photoluminescent compound having a spectral range of absorption and a spectral range of emission; (ii) at least one micrometric or sub-micrometric dielectric photonic structure, optically coupled to said luminescent solar concentrator (LSC), said micrometric or sub-micrometric dielectric photonic structure being able to induce diffusion and/or diffraction of sunlight, preferably diffraction, within said luminescent solar concentrator (LSC), in a spectral range where there is no absorption of said photoluminescent compound; (iii) at least one photovoltaic cell positioned on the outside of at least one side of said luminescent solar concentrator (LSC).

Abstract: Light concentration device comprising: —a primary luminescent solar concentrator (LSC) having a polygonal, circular or elliptic form, comprising at least one photoluminescent compound having a first absorption range and a first emission range; —at least a secondary luminescent solar concentrator (LSC) positioned outside said primary luminescent solar concentrator (LSC), said secondary luminescent solar concentrator (LSC) comprising at least one photoluminescent compound having a second absorption range superimposable to said first emission range and a second emission range. Said light concentration device can be advantageously used in photovoltaic devices (or solar devices) such as, for example, photovoltaic cells (or solar cells), photoelectrolytic cells. Said light concentration device can also be advantageously used in photovoltaic windows.
