摘要： The present invention relates to a luminescent solar concentrator device comprising a receiving surface adapted to receive the solar radiation and a structure made of photoluminescent material, said photoluminescent material being adapted to absorb the solar radiation and to emit, with a net optical gain that is positive or zero, a light radiation having a spectral content that is different from the absorbed solar radiation. The luminescent solar concentrator device also comprises a transmission surface adapted to transmit the light radiation emitted by said photoluminescent material, said transmission surface being optically associable with at least one photovoltaic cell. There are also provided filtering means, adapted to select the spectral content of the light radiation emitted by said photoluminescent material and to convey the light radiation emitted by said photoluminescent material along a predefined main propagation direction.
