NOVELTY - A photoelectric transducer has asymmetrical binuclear metal complex pigment (I), semiconductor fine particles to which a steroid-type compound having a carboxyl group is absorbed, and steroid structure. The photoelectric transducer is obtained by adsorbing asymmetrical binuclear metal complex pigment (I), after adsorbing steroid-type compound to the semiconductor fine particles. The proton of carboxyl group of the steroid-type compound is substituted by a monovalent cation.    USE - Photoelectric transducer is used for photogalvanic cell (claimed).    ADVANTAGE - The photoelectric transducer has excellent photoelectric conversion efficiency.    DETAILED DESCRIPTION - A photoelectric transducer has asymmetrical binuclear metal complex pigment of formula: (L1)2M1(BL)M2(L2)2(X)n (I), semiconductor fine particles to which a steroid-type compound having a carboxyl group is absorbed, and steroid structure. The photoelectric transducer is obtained by adsorbing asymmetrical binuclear metal complex pigment (I), after adsorbing steroid-type compound to the semiconductor fine particles. The proton of carboxyl group of the steroid-type compound is substituted by a monovalent cation.    M1,M2=transition metal;    L1,L2=chelate-type ligand which is coordinated in multiple positions;    X=counter ion;    n=number of counter-ions required to neutralize electric charge of complex;and    BL=crosslinking ligand having at least two cyclic structures containing hetero atom.    The ligand atom coordinated to M1 and M2 is hetero atom contained in the cyclic structure of asymmetrical binuclear metal complex pigment (I). L1 has a substituent which is fixed to semiconductor fine particles. INDEPENDENT CLAIMS are included for the following:    (1) photogalvanic cell, which has photoelectric transducer; and    (2) manufacture of photoelectric transducer, which involves immersing semiconductor fine particles in a solution containing asymmetrical binuclear metal complex pigment (I), adsorbing asymmetrical binuclear metal complex pigment (I) to semiconductor fine particles, immersing semiconductor fine particles in a solution containing steroid-type compound and adsorbing steroid-type compound to semiconductor fine particles.
