PHOTOSENSITIZER, AND PHOTOVOLTAIC DEVICE USING THE SAME

PROBLEM TO BE SOLVED: To provide a less expensive photosensitizer having a high conversion efficiency, and a photovoltaic device using such photosensitizer.SOLUTION: A photosensitizer has, in one molecule, a structure expressed by the general formula (1). In the general formula (I), Rto Rrepresent,...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a less expensive photosensitizer having a high conversion efficiency, and a photovoltaic device using such photosensitizer.SOLUTION: A photosensitizer has, in one molecule, a structure expressed by the general formula (1). In the general formula (I), Rto Rrepresent, independently of one another, H, a carbonyl-containing group, a phosphoric ester group, an alkyl group having 1-30 carbon atoms, an alkenyl group having 2-30 carbon atoms, an alkoxyalkyl group having 1-30 carbon atoms, an amino alkyl group having 1-30 carbon atoms, a perfluoroalkyl group having 1-30 carbon atoms, an aryl group having 6-30 carbon atoms, an aralkyl group having 7-30 carbon atoms, or an alkyl group, alkenyl group, aryl group or aralkyl group which has a carbonyl group.
