Abstract

Disubstituted diaryloxybenzoheterodiazole compound of general formula (1): in which:—Z represents a sulfur atom, an oxygen atom, a selenium atom; or an NR5 group in which R5 is selected from linear or branched C1-C20, preferably C1-C8, alkyl groups, or from optionally substituted aryl groups;—R1, R2 and R3 are as defined in the claims. The said disubstituted diaryloxybenzoheterodiazole compound of general formula (I) can advantageously be used as a spectrum converter in luminescent solar concentrators (LSCs) which are in turn capable of improving the performance of photovoltaic devices (or solar devices) selected, for example, from photovoltaic cells (or solar cells), photovoltaic modules (or solar modules) on either a rigid substrate or a flexible substrate.
