Abstract

Luminescent solar concentrator (LSC) comprising at least one disubstituted benzoheterodiazole compound of general formula (I), in which: —Z represents a sulfur atom, an oxygen atom, a selenium atom; or an NR6 group in which R6 is selected from linear or branched C1-C20, preferably C1-C8, alkyl groups, or from optionally substituted aryl groups; —R1, R2 and R3, which are the same or different, represent a hydrogen atom; or are selected from linear or branched C1-C20, preferably C1-C8, alkyl groups, optionally containing heteroatoms, optionally substituted cycloalkyl groups, optionally substituted aryl groups, optionally substituted linear or branched C1-C20, preferably C1-C8, alkoxyl groups, optionally substituted phenoxyl groups, or —COOR7 groups or —OCOR7 groups in which R7 is selected from linear or branched C1-C20, preferably C1-C8, alkyl groups, or is a cyano group, provided that when the substituents R1 represents a hydrogen atom, at least one of the substituents R2 and R3 represents an optionally substituted aryl group or an optionally substituted phenoxyl group; —or R1 and R2, can optionally be linked together so as to form, together with the carbon atoms to which they are l…
