Abstract:
(EN) [Problem] To provide a photoelectric conversion element and a photoelectrochemical cell that exhibit high IPCE in a long-wavelength region, achieve good photoelectric conversion efficiency, and moreover excel in durability, as well as a dye for use therein. [Solution] A photoelectric conversion element comprising, on a conductive substrate, a layer structure; the layer structure including a photoreceptor which has a layer of a fine particulate semiconductor which has adsorbed dye, a charge-transfer body, and a counter electrode; the photoelectric conversion element characterized in that at least one of the dyes has a structure represented by formula (1). (In the formula, Q represents an aromatic ring. X1 and X2 represent sulfur atoms, selenium atoms, oxygen atoms, or CR1R2. R1 and R2 represent alkyl groups. R and R' are alkyl groups or aromatic groups. P1 represents a specific group of atoms. P2 represents a group of atoms necessary to form a polymethine dye. P1 and P2 are different. W1 represents a counter ion, where necessary to neutralize charge.)
(FR) L'invention vise à proposer un élément de conversion photoélectrique et une pile photoélectrochimique qui présentent un rendement de conversion photon incident-courant (IPCE) élevé dans une région de grande longueur d'onde, présentent une bonne efficacité de conversion photoélectrique et de plus excelle en termes de durabilité, ainsi qu'un colorant pour une utilisation dans ceux-ci. A cet effet, est proposé un élément de conversion photoélectrique comprenant, sur un substrat conducteur, une structure en couches, la structure en couches comprenant un photorécepteur qui présente une couche d'un semi-conducteur particulaire fin qui présente un colorant adsorbé, un corps de transfert de charge et une contre-électrode ; l'élément de conversion photoélectrique étant caractérisé en ce qu'au moins l'un des colorants présente une structure représentée par la formule (1). (Dans la formule, Q représente un cycle aromatique. X1 et X2 représentent des atomes de soufre, des atomes de sélénium, des atomes d'oxygène ou CR1R2. R1 et R2 représentent des groupes alkyle. R et R' sont des groupes alkyle ou des groupes aromatiques. P1 représente un groupe spécifique d'atomes. P2 représente un groupe d'atomes nécessaires pour former un colorant à base de polyméthine. P1 et P2 sont différents. W1 représente un contre-ion, lorsque nécessaire pour neutraliser la charge).
