CONJUGATED POLYMER COMPOSITION AND PHOTOELECTRIC CONVERSION ELEMENT USING SAME

WIPO Patent Application WO/2013/018853

A1

Provided is a conjugated polymer composition whereby a phase-separated structure ideal for a photoelectric conversion element can be formed, and whereby a favorable organic thin film that is highly soluble in solvents can be formed. This conjugated polymer composition has a main chain including a divalent heterocyclic group comprising a fused-ring π-conjugated backbone, has a side chain which is an alkoxy group or alkyl group optionally substituted with a fluorine atom or hydroxyl group, and contains at least two types of conjugated polymers having a number average molecular weight in terms of polystyrene of at least 10,000 g/mol, wherein the difference between the conjugated polymer having the greatest value and the conjugated polymer having the lowest value for a solubility parameter of each of the conjugated polymers is 0.6 to 2.0.
