Title:
SQUARYLIUM DYE, DYE-SENSITIZED SOLAR CELL USING THE DYE, AND PHOTOELECTRIC CONVERSION ELEMENT USING THE DYE
Document Type and Number:
WIPO Patent Application WO/2011/108481
Kind Code:
A1
Abstract:
Disclosed are: a novel squarylium dye which is capable of improving the photoelectric conversion efficiency in the near infrared region; and a dye-sensitized solar cell and a photoelectric conversion element, each using the squarylium dye and having improved photoelectric conversion efficiency.
Specifically disclosed is a squarylium dye represented by formula (1). In the formula, R1-R7 and R'1-R'7 each represents a hydrogen atom, an alkyl group, a sulfoalkyl group, a cycloalkyl group, an alkoxyl group, an aryl group, a halogen atom or the like; X and Y each represents a hydrogen atom or -COOR (wherein R represents a hydrogen atom or a C1-C12 alkyl group), with both or either of X and Y being -COOR; and R8 and/or R'8 represents a C3-C30 alkyl group, a C3-C30 halogen-substituted alkyl group, a C3-C30 hydroxycarbonylalkyl group, RCOO- or RSO3- (wherein R represents a C1-C30 alkyl group).
