PHOTOELECTRIC CONVERSION ELEMENT AND METHOD FOR PRODUCING THE SAME

摘要

To provide a photoelectric conversion element being excellent in photoelectric conversion efficiency and stability of photoelectric conversion function, a method for producing the photoelectric conversion element, and a solar cell using the photoelectric conversion element. A photoelectric conversion element having a substrate, a first electrode, a photoelectric conversion layer containing a semiconductor and a sensitizing pigment, a hole transport layer having a conductive polymer, and a second electrode, wherein the hole transport layer is formed by bringing the photoelectric conversion layer into contact with a solution containing a conductive polymer precursor and an oxidizer at a ratio of 0.1<[Ox]/[M] (wherein [Ox] is the molar concentration of the oxidizer; and [M] is the molar concentration of the conductive polymer precursor), and irradiating the photoelectric conversion layer with light.
