Said diaryloxybenzoheterodiazole compound disubstituted with thienothiophene groups having general formula (I) can be advantageously used as an electron acceptor compound in organic photovoltaic devices (or solar devices) selected, for example, from binary, ternary, quaternary, organic photovoltaic cells (or solar cells), having both simple and tandem architecture, organic photovoltaic modules (or solar modules), both on rigid support and on flexible support. Furthermore, said diaryloxybenzoheterodiazole compound disubstituted with thienothiophene groups having general formula (I) can be advantageously used in perovskite-based photovoltaic cells (or solar cells) in the layer based on electron transport material ("Electron Transport Layer" - ETL). Moreover, said diaryloxybenzoheterodiazole compound disubstituted with thienothiophene groups having general formula (I) can be advantageously used in the construction of organic thin film transistors (OTFTs), or of organic field effect transistors (OFETs).
