This provides a photoelectric conversion device that encapsulates a compound represented by formula (1) and formed on a substrate in an oxide semiconductor nanoparticle film. In formula (1), m1 represents an integer from 1 to 4; M represents a semimetal atom; Y, Y, and Y independently represent a hydrogen atom or an aromatic residue; Z and Z independently represent a halogen atom; Ar and Ar independently represent an aromatic ring; and X represents one or more substituents selected from the group consisting of formulas (2), (3), and (4) as a substituent on the aromatic ring(s) Ar and/or Ar.
Novel boron–dibenzopyrromethene dyes with thienyl-cyanoacrylic acid units were synthesized and characterized for application in dye-sensitized solar cells (DSSCs).
