PHOTOELECTRIC CONVERSION MATERIAL, METHOD FOR PRODUCING THE SAME, AND ORGANIC THIN-FILM SOLAR CELL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a photoelectric conversion material which exhibits excellent characteristics as an electron donor or an electron acceptor.SOLUTION: A BHJ (bulk hetero-junction organic thin-film) solar cell 10 includes a photoelectric conversion layer 16 in which a donor domain 26 and an acceptor domain 28 are mixed. The donor domain 26 comprises a nanographene polymer obtained by further reacting polyphenylene, and the nanographene polymer acts as a donor. An acceptor forming the acceptor domain 28 is, for example, a phenyl Cbutyric acid methyl ester (PCBM).
