Concentrador solar luminiscente y dispositivo fotovoltaico que lo comprende

摘要

The invention relates to a luminescent solar concentrator comprising a substrate containing an at least semi-transparent organic polymer matrix in turn containing distributed organic fluorescent molecules capable of absorbing solar radiation, at least some of the fluorescent molecules being associated with one another by dipole interactions capable of transferring non-radiative energy from one to another. The organic polymer matrix is a single-layer matrix (3) in which at least three groups of different organic fluorescent molecules (7, 8, 9) are distributed and associated with one another such as to form non-radiative energy transfer cascades by means of Förster resonance energy transfer (FRET).
