The guided wave road which is used with the optical generating set and the optical generating set

摘要

The present invention relates to a luminescent photovoltaic generator (1) and a waveguide for use in such a photovoltaic generator. The photovoltaic generator comprises a photovoltaic cell (4) and a waveguide comprising a transparent matrix (2) having particles of an inorganic luminescent material dispersed therein and/or an inorganic luminescent material disposed at least one side thereof (6). The waveguide is associated with the photovoltaic cell (4), such that, in use, at least some of the light emitted from the luminescent material passes into the photovoltaic cell (4) to generate a voltage in the cell. In preferred embodiments, the inorganic luminescent material is a line emitter and the emission is due to a forbidden electronic transition within the material. The inorganic luminescent material may be selected from an inorganic phosphor, an inorganic fluorescent material and quantum dots, quantum rods and quantum core/shell systems. The photovoltaic generator (1) is an alternative to or an improvement upon known photovoltaic generators, which generally suffer from a lack of power yield per area.
