NOVELTY - A photoelectric conversion element consists of an electrode (10) consisting of a dye containing a cyanine compound and supported on a carrier (12).    USE - Photoelectric conversion element e.g. solar cell.    ADVANTAGE - The photoelectric conversion element has improved conversion efficiency.    DETAILED DESCRIPTION - A photoelectric conversion element consists of an electrode consisting of a dye containing a cyanine compound and supported on a carrier. The cyanine compound is of formula: R1-Q=R2.(Z(power)(p-))q.    R1=group chosen from groups of formulae (i)-(v);    R2=group chosen from groups of formulae (vi)-(ix);    Q=coupling group having 1-7C methine chain skeleton;    Z(power)(p-)=p-valent anion;    p=1 or 2;    q=coefficient which keeps electric charge neutral;    R10-R13,R18-R23,R25-R30,R32-R35,R37-R40,R42-R65=H, hydroxy, nitro, cyano, halo, or alkyl, alkoxy, aryl, arylalkyl or their derivatives, with at least one of R10 and R11, and at least one of R12 and R13 being detached to form double bond, or being connected to form a ring structure;    R14,R24,R31,R36,R41=alkylene;    X=-C(R15)(R16)-, -N(R17)-, sulfur, oxygen, selenium, or tellurium;    R15-R17=H, group of formula (x), or group obtained by removing alkyl, alkoxy, aryl, arylalkyl, or their derivatives from group (x);    Y1-Y5=carboxylic acid group or carboxylate ion group;    bonding between L1 and T1=double bond or triple bond;    L1=carbon;    T1=carbon, oxygen or nitrogen;    x,y,z=0 or 1;    R66-R68=H, hydroxy, nitro, cyano, halo, or 1-4C (halo)alkyl;    R69=H, hydroxy, nitro, cyano, halo, 1-4C (halo)alkyl, or 1-4C (halo)alkoxy;    R66+R69,R67+R68=ring;and    n=0-4.    (i) When T1 is oxygen, x and y are 0; and (ii) When T1 is nitrogen, (y+z) is 0 or 1. An INDEPENDENT CLAIM is included for photoelectric conversion element dye.
