Title:
PHOTOELECTRIC CONVERSION ELEMENT AND PHOTOELECTROCHEMICAL CELL
Document Type and Number:
WIPO Patent Application WO/2011/108611
Kind Code:
A1
Abstract:
Disclosed is a photoelectric conversion element having high conversion efficiency and furthermore having excellent durability. Further disclosed is a photoelectrochemical cell. The photoelectric conversion element, which comprises a layered structure containing a counter electrode, a charge-transfer body, and a photosensitive body—which has a semiconductor microparticle layer to which a pigment is adsorbed—on a conductive support body, is characterized by the aforementioned pigment having the structure represented by the belowmentioned general formula (1), and by the aforementioned charge-transfer body having an electrolyte composition containing a heterocyclic quaternary salt compound. (In the general formula (1), A1 represents a five- to seven-membered nitrogen-containing heterocycle formed from bonding with a benzene ring. L1 represents an electron-transferring linking group containing a particular heterocycle of a thiophene ring or the like. R1 and R3 each independently represent a hydrogen atom or a substituent group. R2 represents a hydrogen atom or a substituent group. B1 represents a methylene group substituted with an electron-withdrawing group or a heterocyclic acidic nucleus, B1 has at least one acidic group, and n1 represents an integer from 1 to 12.)
