NOVELTY - An electrode layer comprises a porous film made of oxide semiconductor fine particles sensitized with a dye.    USE - The electrode layer is useful in manufacturing a photoelectric conversion device used in a dye sensitized solar cell, and an organic electronic device, in particular an organic light-emitting diode (OLED) or an organic field-effect transistor (OFET). Also, the compound of Formula (I) is used as a dye in a dye sensitized solar cell (all claimed).    ADVANTAGE - The electrode layer has a particularly good dye absorption property on the electrode, giving high long-term dynamic stability control (DSC) stability, high long-term performance and high energy conversion efficiency.    DETAILED DESCRIPTION - An electrode layer comprises a porous film made of oxide semiconductor fine particles sensitized with a dye of Formula (I).    n=1, 2, 3, 4, 5 or 6;    R1 and R2=hydrogen, unsubstituted 1-20C-alkyl where alkyl is uninterrupted or interrupted by O, S, CO, NR14 or combinations, substituted 1-20C-alkyl where alkyl is uninterrupted or interrupted by O, S, CO, NR14 or combinations, unsubstituted 1-20C-cycloalkyl where alkyl is uninterrupted or interrupted by O, S, CO, NR14 or combinations, substituted 1-20C-cycloalkyl where alkyl is uninterrupted or interrupted by O, S, CO, NR14 or combinations, unsubstituted 6-20C-aryl, substituted 6-20C-aryl, unsubstituted 6-20C-heteroaryl, substituted 6-20C-heteroaryl; or R1 can additionally be a residue of formula D;    D=a residue of formulas (D.1) and (D.2); and    A=a residue of Formulas eg.(A.5) and (A.7) (Full Definition is given in the DEFINITONS Section under Full Definitions).    INDEPENDENT CLAIMS are included for:    (1) photoelectric conversion device which comprises the electrode layer;    (2) dye sensitized solar cell which comprises the photoelectric conversion device;    (3) organic electronic device, in particular an organic light-emitting diode (OLED) or an organic field-effect transistor (OFET), which comprises a photoelectric conversion device; and    (4) a compound of Formula (I).
