<P>PROBLEM TO BE SOLVED: To provide a light sensitizing type photoelectric transducer of which the manufacturing process is simple and easy, which can be manufactured inexpensively, and furthermore in which a specific light sensitizer having a high photoelectric transfer efficiency is adsorbed to a semiconductor thin film electrode. <P>SOLUTION: This photoelectric transducer is composed of a transparent electrode, a semiconductor electrode, the counter electrode and an electrolytic solution, and the light sensitizer expressed by a general formula (1) is adsorbed to the semiconductor electrode. In the formula, R<SP>1</SP>and R<SP>2</SP>show respectively and independently either one of a hydrogen atom, an alkyl group, a substituted or non-substituted aryl group, an alcoxyalkyl group or an aralkyl group, R<SP>3</SP>and R<SP>4</SP>are respectively and independently the alkyl group or coupled together and form a ring, A shows a bi-valent atom group which forms a conjugate system together with the adjacent atom group, W and Y are respectively and independently either of the hydrogen atom, the alkyl group, or a halogen atom, L is the ring either of thiophene or furan, n is an integer of 0 to 5, and m is the integer of 0 to 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
