Patent ID: 8664518

Claim:
An organic photoelectric conversion element comprising: a first electrode; a second electrode; and an organic photoelectric conversion layer sandwiched between the first electrode and the second electrode, wherein the first electrode comprises: a conductive fiber layer; and a transparent conductive layer containing a conductive polymer comprising a π conjugated conductive polymer and a polyanion, and an aqueous binder, and at least a part of the transparent conductive layer containing the conductive polymer and the aqueous binder is cross-linked therein, wherein the aqueous binder comprises Polymer (A) containing the following recurring units: wherein X 1 to X 3 each respectively represent a hydrogen atom or a methyl group; R 1 to R 3 each respectively represent an alkylene group having a carbon number of 5 or less; l, m and n each respectively represent a ratio of each recurring unit when the total molar number of monomers composing Polymer (A) is set to be 100, provided that l, m and n satisfy the relationship of: 50≦1+m+n≦100.
