Method of producing photoelectric conversion element, photoelectric conversion element and photoelectrochemical cell

摘要

A method of producing a photoelectric conversion element, which contains an electrically conductive support, a photosensitive layer having porous semiconductor fine particles that have adsorbed a dye formed on the support, a charge transfer layer; and a counter electrode; containing the steps of: applying a dispersion liquid, in which the content of solids excluding semiconductor fine particles is 1% 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 semiconductor fine particles by a dye having a structure represented by Formula (1):M(LL¹)m₁(LL²)m₂(X)m₃·CI  Formula (1)wherein M represents a metal atom, LL¹, LL², and X each are a ligand, CI represents a counter ion, m₁ represents an integer of 1 to 3, m₂ and m₃ each represent an integer of 0 to 2.
