Photosensitizer, semiconductor electrode, and photoelectric conversion device

摘要

A photosensitizer containing guanidine derivative expressed in General Formula (a) as and a photosensitizer expressed in General Formula (X) as D^(m+m')-(A⁺)_m(A^'+)_m' or in General Formula (Y) as D^(m+m'+n)-(A⁺)_m(A^'+)_m'(B⁺)_n (where D has a molecular structure capable of absorbing visible light or infrared ray, A and A' represent the guanidine derivative, and B represents an ion other than the guanidine derivative), and a semiconductor electrode and a photoelectric conversion device employing the photosensitizer are provided. A photosensitizer having a novel structure as well as a semiconductor electrode and a photoelectric conversion device employing the photosensitizer are thus provided.
