Patent ID: 8723163

Claim:
An organic photoelectric conversion device comprising: a pair of electrodes, at least one of which is transparent or semi-transparent; and an organic layer arranged between the electrodes and containing a conjugated polymer compound and a sulfur-containing heterocyclic compound, wherein the sulfur-containing heterocyclic compound has a condensed polycyclic structure or a bithiophene structure represented by a formula (1): wherein, a plurality of R 1 's may be the same or different and each represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, an arylalkyl group, an arylalkoxy group or an arylalkylthio group; a hydrogen atom or atoms contained in these groups may be substituted by a fluorine atom or atoms; and in represents an integer of 0 to 10, and the conjugated polymer compounds have one kind or two or more kinds of the following groups as a repeat unit, with the repeat units being mutually bonded to each other directly or through a linking group interposed therebetween: an unsubstituted or substituted fluorene-diyl group, an unsubstituted or substituted benzofluorene-diyl group, an unsubstituted or substituted dibenzofuran-diyl group, an unsubstituted or substituted dibenzothiophene-diyl group, an unsubstituted or substituted carbazole-diyl group, an unsubstituted or substituted thiophene-diyl group, an unsubstituted or substituted furan-diyl group, an unsubstituted or substituted pyrrole-diyl group, an unsubstituted or substituted benzothiadiazole-diyl group, an unsubstituted or substituted phenylenevinylene group, an unsubstituted or substituted thienylenevinylene group and an unsubstituted or substituted triphenylamine-diyl group, the linking group being selected from the group consisting of phenylene, biphenylene, naphthalene-diyl and anthracene-diyl.
