  • Organic dye for a dye-sensitized solar cell
    Patent number: 9997299
    Abstract: Organic dye for a dye-sensitized solar cell (DSSC) comprising at least one electron-acceptor unit and at least one ?-conjugated unit. Said organic dye is particularly useful in a dye-sensitized photoelectric transformation element which, in its turn, can be used in a dye-sensitized solar cell (DSSC).
    Type: Grant
    Filed: October 1, 2014
    Date of Patent: June 12, 2018
    Assignees: ENI S.p.A., CNRS (CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE)
    Inventors: Paolo Biagini, Jean Roncali, Dora Demeter, Philippe Leriche
