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: Two- or three-dimensional photonic crystals comprising at least of fluorinated polymer are disclosed. The two- or three-dimensional photonic crystals have infiltrated opal or inverse opal structures.
