Abstract
The invention relates to a luminescent solar concentrator comprising a glass or plastic matrix containing colloidal nanocrystals of at least ternary semiconductors based on metals of groups IB and IIIA (groups 11 and 16 respectively in the UIPAC nomenclature) and at least one chalcogen (group VIA, or 16 in the IUPAC nomenclature).
Claims15
A solar concentrator comprising a body made of polymer material or silica-based glass containing colloidal nanocrystals, wherein the nanocrystals are nanocrystals of at least ternary semiconductor chalcogenides, containing transition metals of group IB, or group 11 in the IUPAC nomenclature, metals of group IIIA, or group 13 in the IUPAC nomenclature, and at least one chalcogen of group VIA, or group 16 in the IUPAC nomenclature.
