Paragraph 0055-0057, (2018/05/31)
PROBLEM TO BE SOLVED: To provide a squarilium derivative that is a new compound useful for providing a high efficiency organic thin film solar cell, in which reverse electron transfer is slow, and that is suitable for a donor material to an acceptor material having a high symmetric property; a donor material comprising the same; and an organic thin film solar cell using the same.SOLUTION: An organic thin film solar cell in which at least one layer of an organic layer is laminated between a pair of electrodes includes a layer comprising an asymmetric squarilium derivative represented by the following general formula (1). (In the formula (1), one of substituents R, Ris a substituted or unsubstituted aromatic hydrocarbon group, and the other is a substituted or unsubstituted aliphatic hydrocarbon group.)
