Title:
PHOTOELECTRIC ELEMENT
Document Type and Number:
WIPO Patent Application WO/2011/096508
Kind Code:
A1
Abstract:
Provided is a photoelectric element comprising an electron transport layer, which has excellent electron transport properties and a sufficiently large reaction interface, and showing an excellent conversion efficiency. The photoelectric element comprises a first electrode (4), a second electrode (6), an electron transport layer (1) and a hole transport layer (5), these layers being sandwiched between the first electrode (4) and the second electrode (6), an electrolyte solution and a conductive assistant (3). The electron transport layer (1) comprises an organic compound having an oxidoreduction part that can be repeatedly oxidized and reacted. The electrolyte solution stabilizes the reduced state of the oxidoreduction part. The organic compound and the electrolyte solution together form a gel layer (2). The conductive assistant (3) is present in the gel layer (2) and at least a part of the conductive assistant (3) is in contact with the first electrode (4).
