A method of producing a photoelectric conversion element,
which the element contains an electrically conductive support, a photosensitive layer having porous semiconductor fine particles, a charge transfer layer; and a counter electrode;
containing the steps of:
applying a semiconductor dispersion liquid, in which the content of solids excluding semiconductor fine particles is 10% by mass or less based on the total amount of the dispersion liquid, on the support, to form a coating;
heating the coating, to obtain porous semiconductor fine particles; and
sensitizing the porous particles by adsorption of the following dye:
wherein A represents a group of atoms necessary for forming a ring; at least one of Y1 and Y2 represents an acidic group and the other one represents an electron-attracting group; D represents a dye residue; n represents 1 or a greater integer; L represents a single bond or divalent linking group; and Y3 represents an acidic group.
