Provide are: a conjugated block copolymer capable of increasing the amount of optical absorption by a photoelectric conversion active layer and controlling the morphology thereof and capable of achieving excellent photoelectric conversion efficiency; and a photoelectric conversion element comprising a composition including an electron accepting material and this kind of conjugated block polymer. A π-electron conjugated block copolymer comprising: a polymer block (A) which involving a monomer unit having at least one heteroaryl skeleton selected from the group consisting of a fused π-conjugated skeleton, a fluorene, a carbazole, a dibenzosilole and a dibenzogermole containing at least one thiophene ring in a part of a chemical structure thereof; and a polymer block (B) involving a monomer unit of a thiophene-2,5-diyl group having a substituent at least at a 3-position thereof.
backbone has been used to develop self-doped n-type conductive molecules (QnNs) with high electricalconductivities and good air stability. Intermolecular electron transfer from the amino groups to the quinoidal backbone was found to result in the self-doping. Applying the QnNs as the cathode interlayer (CIL) in organic solar cells led to an outstanding power conversion efficiency (PCE) of up to 18.2 %.
