Title:
PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2008/072568
Kind Code:
A1
Abstract:
Provided is a photoelectric conversion element, which is made of a porous oxide semiconductor layer carrying a sensitizing coloring matter and which includes a first electrode for functioning as a window pole, a second electrode arranged to confront the first electrode, an electrolyte arranged at least partially between the first electrode and the second electrode, and an electrolyte liquid reservoir at least partially between the first electrode and the second electrode. The photoelectric conversion element can clear a power generating area effectively of bubbles thereby to have a long-time durability of improved power generating characteristics.
