Organic photoelectric conversion element and organic solar cell using the same

An organic photoelectric conversion element comprising:

• a transparent first electrode;
• a power generation layer having a p-type organic semiconductor material and an n-type organic semiconductor material;
• and
• a second electrode disposed on a transparent substrate,
• wherein the power generation layer is a bulk heterojunction power generation layer including the p-type organic semiconductor material and the n-type organic semiconductor material, and additionally comprising a compound represented by one of the following formulas (I-A) to (I-E):
• wherein R2 and R3 represent a halogen atom, a substituted or unsubstituted alkyl group (—Ra), a hydroxyalkyl group (—Ra(OH)), an alkoxy group (—ORa), an aryloxy group, an amino group (—NH2), an amino group (—NHRa), an amino group (—N(Ra)2), a thioether group (—SRa), an ester group, —CORa, —COORa, —NHCORa, —NHCOORa, —NHSO2Ra, or an alkylcarbonyloxy group (—OCORa), in which Ra represents a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms or a substituted or unsubstituted aryl group having 6 to 20 carbon atoms, and m5 and l5 each represent an integer of from 0 to 4.
