Title:
INK COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2022/224893
Kind Code:
A1
Abstract:
Provided is an ink composition which requires no trial and error to make it possible to more reliably carry out filtration without clogging a filter in a production step and which is unlikely to cause an electrical defect such as electrical insulation or a short circuit. Also provided is a method for producing an ink composition which makes it possible to more improve the efficiency of producing an ink composition and the efficiency of producing a photoelectric conversion element. An ink composition for producing a photoelectric conversion element comprises a p-type semiconductor material, an n-type semiconductor material, and a solvent, wherein the p-type semiconductor material contains a polymer compound which has a z average molecular weight of less than 5.0×105. The p-type semiconductor material preferably contains a polymer compound which has a weight-average molecular weight of more than 6.0×104.
