Disubstituted diaryloxybenzoheterodiazole compound of general formula (I): in which:

Disubstituted diaryloxybenzoheterodiazole compounds

Disubstituted diaryloxybenzoheterodiazole compound of general formula (1): in which:&#x2014;Z represents a sulfur atom, an oxygen atom, a selenium atom; or an NRgroup in which Ris selected from linear or branched C-C, preferably C-C, alkyl groups, or from optionally substituted aryl groups;&#x2014;R, Rand Rare 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. 

Disubstituted naphthoheterodiazole compound having general formula (I): wherein: Said disubstituted naphthoheterodiazole compound having general formula (I) can be advantageously used as spectrum converter in luminescent solar concentrators (LSCs), in its turn capable of improving the performances of photovoltaic devices (or solar devices) selected, for example, from photovoltaic cells (or solar cells), photovoltaic modules (or solar modules), on both rigid and flexible supports.

Disubstituted naphthoheterodiazole compounds

The present invention relates to a photoluminescent composition comprising an acene compound having general formula (I) or (Ia) and a benzothiadiazole compound having general formula (II), and the relative use as photoluminescent composition in a spectrum converter. A spectrum converter comprising the photoluminescent composition defined above, comprising the above compounds having general formula (I) or (Ia) and (II) and a solar device comprising said spectrum converter, are also described.
