A photoelectric material having high efficiency and superior durability is provided. The photoelectric material includes a semiconductor and a photosensitizing dye attached to the semiconductor, wherein the dye is a phthalocyanine derivative, a dioxazine derivative or an indigo derivative having at least one interlocking group and at least one hydrophobic group selected from the group consisting of monovalent substituted and unsubstituted aliphatic hydrocarbon groups and monovalent substituted and unsubstituted alicyclic hydrocarbon groups. The hydrophobic group is preferably an alkyl group with 3 to 12 carbon atoms. The interlocking group is a carboxyl group, a sulfonic acid group, phosphono group or the like. In manufacturing the photoelectric material, the dye is dissolved in a hydrophobic and/or aprotic solvent. In order to attach the dye to the semiconductor, the semiconductor is dipped in the dye solution.
