ORGANIC DYE SENSITIZER, PREPARATION METHOD AND USE IN PHOTOVOLTAIC CONVERSION

Disclosed are an organic dye sensitizer, preparation method and use in photovoltaic conversion thereof. Provided is an organic dye sensitizer having a general formula as represented by formula (I), wherein A is an electron-deficient unit and electron acceptor; D is an electron-rich unit and electron donor; N is an electron neutral organic structural unit having no obvious electron push-and-pull capability; is a connecting unit with a conjugated structure; Ar is a conjugate aromatic ring system chromophore unit or a conjugate combination of two or more of the structural units; B is a structural unit bonded to the nanopore surface of the photoanode of a dye sensitized battery cell so as to transport the electrons excited by irradiating dye sensitizer molecules with visible and ultraviolet light, forming electric currents; n is 1, 2, 3, 4, 5, or 6. Cette invention concerne un sensibilisateur de type colorant organique, son procédé de préparation et utilisation dans la conversion photovoltaïque. Le sensibilisateu
