Title:
PHOTOELECTRIC CONVERSION ELEMENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2014/046145
Kind Code:
A1
Abstract:
[Problem] To provide: a photoelectric conversion element which has excellent photoelectric conversion efficiency and stability of photoelectric conversion function; a method for manufacturing this photoelectric conversion element; and a solar cell which uses this photoelectric conversion element. [Solution] A photoelectric conversion element which comprises a substrate, a first electrode, a photoelectric conversion layer that contains a semiconductor and a sensitizing dye, a hole transport layer comprising a conductive polymer, and a second electrode. This photoelectric conversion element is characterized in that the hole transport layer is formed by bringing the photoelectric conversion layer into contact with a solution, which contains a conductive polymer precursor and an oxidant at a ratio satisfying 0.1 < [Ox]/[M] (wherein [Ox] represents the molar concentration of the oxidant and [M] represents the molar concentration of the conductive polymer precursor), and then irradiating the photoelectric conversion layer with light.
