METHOD FOR MANUFACTURING PHOTOELECTRIC CONVERSION ELEMENT, AND PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/131747
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a method for manufacturing a photoelectric conversion element, which has a high open voltage (Voc) or a high fill factor (FF) in a low light quantity region, and which includes a photoelectric conversion film that is composed of an organic thin film, and to provide a photoelectric conversion element.
[Solution] This method for manufacturing a photoelectric conversion element is provided with: a step of forming a hole injection layer by applying, to a transparent substrate and a transparent electrode disposed on the transparent substrate, a first P-type organic semiconductor and a solvent containing an oxidizing agent that can oxidize the first P-type organic semiconductor, drying the semiconductor and the solvent, and oxidizing the first P-type organic semiconductor using the oxidizing agent; a step of forming a photoelectric conversion layer by applying a solvent containing an N-type organic semiconductor and a second P-type organic semiconductor to the hole injection layer, and drying the solvent; and a step of forming a metal electrode by forming a metal layer on the photoelectric conversion layer.
