  • Chromophores, method for the preparation thereof, and use of same
    Patent number: 9109119
    Abstract: The invention relates to a chromophore of general formula: in which: R1 represents C1-C4 alkyl; R2 represents a sterically hindered group; R3 represents a pi-conjugated system; Y represents O, S, NH or is absent; R4 represents a C3-C18, preferably C3-C8 and more preferably C3 alkyl group; M represents a metal from Group III or IV of the Periodic Table; n is an integer, to its process of preparation and to its uses.
    Type: Grant

  • Method for Preparing a Photovoltaic Thin Film Having a Heterojunction
    Publication number: 20150179947
    Abstract: The present invention relates to a method for preparing a photovoltaic thin film having a heterojunction by depositing a composition, including a first organic electron-donor semiconductor CP and a second organic electron-acceptor semiconductor CN, onto a substrate and then carrying out phase segregation, including: a step (E1) of preparing a first mixture M1 including the organic semiconductors CN and CP within a solvent medium; and then a step (E2) of adding an additive, having at least one N3 function, to the said mixture.

  • Methods of photochemical hydrolysis-polycondensation of cross-linkable chromophores with steric hindrance, catalysed by a photogenerated acid, and the applications thereof
    Patent number: 8722318
    Abstract: The invention relates to a process for the hydrolysis-polycondensation of a sterically hindered crosslinkable chromophore, characterized in that the hydrolysis-polycondensation is catalyzed with an acid released by a photoacid generator (PAG).
