Theoretical Characterization and Design of Efficient Photoactive Materials Based on Naphthopyrrole and Naphthothiophene Derivatives Aimed Towards Organic Solar Cells
Abstract:. In this research we have designed electron donors D-π-A type containing two different π fragments to obtain naphthopyrrole (D-NPR-A) and naphthotiophene (D-NTP-A) derivatives, proposed for the use in organic bulk hetero-junction (BHJ) solar cells (OSCs). These derivatives were characterized by DFT and TD-DFT calculations. For all the electron donors the anchorage fragment was 2-methylenemalononitrile, while the chromophore fragment was spanned between diphenylamine, triphenylamine, thiophene. Properties affe… Show more
