We report on the optical efficiency enhancement of luminescent solar concentrators based on a push– pull fluorophore realized using high dielectric contrast polymer distributed Bragg reflectors as back mirrors. The Bragg stacks are obtained by alternating layers of cellulose acetate and thin films of a new stable and solution processable...

Photonic crystals (PhCs) are defined as composites made of media bearing different dielectric constant or refractive index ordered in a mono, bi or tridimensional periodic structure, and whose lattice constant is comparable to the wavelength of visible or near-infrared light. PhCs are nowadays exploited in functional architecture, enhancement...
