Title:
A photoelectric conversion element and a manufacturing method for the same
Document Type and Number:
Japanese Patent JP6252479
Kind Code:
B2
Abstract:
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.
