Title:
DYE FOR PHOTOELECTRIC CONVERSION ELEMENT AND PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2010/038589
Kind Code:
A1
Abstract:
A photoelectric conversion element having improved conversion efficiency.  The photoelectric conversion element comprises a working electrode (10), a counter electrode (20) and an electrolyte-containing layer (30), and the working electrode (10) is provided with a metal oxide semiconductor layer (12) which supports a dye (13).  The dye (13) contains a cyanine compound having a methine chain, indolenine skeletons bonded to both ends of the methine chain and anchor groups introduced to nitrogen atoms contained in the indolenine skeletons.  In this photoelectric conversion element, the electron injection efficiency to the metal oxide semiconductor layer (12) is increased and separation of the dye (13) from the metal oxide semiconductor layer (12) is made less likely to occur.
