  • Alternative acceptor materials based on hexabenzocoronene
    Patent number: 10886472
    Abstract: The invention relates to a compound comprising a hexabenzocoronene core to which are bonded, in position 2 and 5, a polymer ZP46, optionally via a spacer, and to which are bonded substituents selected from a group —COOH, —C?N, —N+?C, —O—C?N or CF3, at position 1, 3, 4, and 6; a donor:acceptor layer comprising it, and a device comprising such a compound and such a layer and its use in the field of organic photovoltaic cells.

  • Hexabenzocoronene-based compound for organic photovoltaic cells
    Patent number: 10454034
    Abstract: Provided is a hexabenzocoronene-based compound and a donor: acceptor layer having this compound. Also provided are processes for manufacturing this compound and to a photovoltaic cell having at least one hexabenzocoronene-based compound. The hexabenzocoronene-based compound has following formula I: wherein R1, R3, R4 and R6 are independently from each other chosen among a carboxylic (—COOH) group, a cyano (—C?N) group, an isocyano (—N+?C?) group, a cyanate (—O—C?N) group and a —F group, and R2 and R5 are, independently from each other, chosen among a poly(3-oxypentylthiophene) (P3OPT) substituent and a poly(3-hexylthiophene) (P3HT) substituent.
