Title:
PHOTOELECTRIC CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2003/098731
Kind Code:
A1
Abstract:
Photoelectric conversion device (1) comprising semiconductor electrode (15) having semiconductor layer (7) carrying a sensitizing dye, counter electrode (9) arranged opposite to the semiconductor electrode (15) and electrolyte layer (13) arranged between the semiconductor electrode (15) and the counter electrode (9), wherein the electrolyte layer (13) contains a compound having in its molecule a nitrogen atom with unshared electron pair and an iodide (I3-) whose concentration is in the range of 0.06 to 6 mol/dm3. This photoelectric conversion device enables maintaining excellent conversion efficiency for a prolonged period of time.
