Colorless light-emitting solar concentrator with absorption extending to the near infrared region based on nanocrystals of at least ternary chalcogenide semiconductors free of heavy metals

摘要

The present invention relates to at least ternary semiconductors based on metals of groups IB and IIIA (groups 11 and 16 in IUPAC nomenclature, respectively) and at least one chalcogen (groups VIA or 16 in IUPAC nomenclature). The invention relates to a light-emitting solar concentrator composed of a glass or plastic matrix containing colloidal nanocrystals. [Selection] Figure 1
