Disubstituted fluoroaryloxybenzoheterodiazole compound having general formula (I): Said disubstituted fluoroaryloxybenzoheterodiazole compound having general formula (I) may be advantageously used as a spectrum converter in luminescent solar concentrators (LSCs) capable, in turn, of improving the performance of photovoltaic devices (or solar devices) selected, for example, from photovoltaic cells (or solar cells), photovoltaic modules (or solar modules), either on a rigid support, or on a flexible support.

Disubstituted fluoroaryloxybenzoheterodiazole compounds

There is a diaryloxybenzoheterodiazole compound di-substituted with thienothiophenic groups having general formula (Ia): The diaryloxybenzoheterodiazole compound di-substituted with thienothiophenic groups having general formula (Ia) can be advantageously used as a spectrum converter in luminescent solar concentrators (LSCS) capable, in turn, of improving the performance of photovoltaic devices (or solar devices), selected for example, between photovoltaic cells (or solar cells), photovoltaic modules (or solar modules), either on a rigid support, or on a flexible support. More particularly, said photovoltaic devices (or solar devices) can be advantageously used in the construction of greenhouses.
