DYE-SENSITIZED SOLAR CELL FOR LOW LIGHT INTENSITIES

摘要

The present invention is a dye-sensitized solar cell for low illumination, which includes a first electrode having a transparent substrate and a transparent conductive film provided on the transparent substrate; a second electrode that faces the first electrode; an oxide semiconductor layer provided on the first electrode or the second electrode; an electrolyte that is provided between the first electrode and the second electrode; a photosensitizing dye that is adsorbed to the oxide semiconductor layer; and a co-adsorbent that is adsorbed to the oxide semiconductor layer together with the photosensitizing dye, the photosensitizing dye being a metal complex compound represented by the following formula (1), and the co-adsorbent including an organic compound represented by the following formula (2) or the like:wherein in formula (1), M represents Ru; R1, R2, R3, and R4 each independently represent a monovalent cation; and R5 and R6 each independently represent a halogen group or the like; andwherein in formula (2), n represents an integer from 0 to 5; and R7 represents a monovalent group having a π-conjugated structure or the like.
