Abstract
Official abstract text for this publication.
A photoelectric conversion element is provided. The photoelectric conversion element includes a first electrode and a second electrode. The first electrode is covered with an electron transport layer. The electron transport layer is covered with a material represented by the following formula (1): wherein each of R 1 and R 2 independently represents a straight-chain or branched-chain alkyl group, Ar represents a substituted or unsubstituted aryl group, each of X 1 and X 2 independently represents a substituted or unsubstituted aryl group or a substituted or unsubstituted saturated hydrocarbon group, n represents an integer of from 1 to 3, and Ar may share bond connectivity with X 1 or X 2 to form a ring. The second electrode is facing the electron transport layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A photoelectric conversion element, comprising: a first electrode, the first electrode covered with an electron transport layer, the electron transport layer covered with a material represented by the following formula (1): wherein each of R 1 and R 2 independently represents a straight-chain or branched-chain alkyl group, Ar represents a substituted or unsubstituted aryl group, each of X 1 and X 2 independently represents a substituted or unsubstituted aryl group or a substituted or unsubstituted saturated hydrocarbon group, n represents an integer of from 1 to 3, and Ar may share bond connectivity with X 1 or X 2 to form a ring; and a second electrode, the second electrode facing the electron transport layer. 2. The photoelectric conversion element according to claim 1 , wherein the material represented by the formula (1) is a material represented by the following formula (2): wherein each of R 1 and R 2 independently represents a substituted or unsubstituted alkyl group; R 3 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxyl group, or hydrogen atom; and n represents an integer of from 1 to 3. 3. The photoelectric conversion element according to claim 1 , wherein the electron transport layer includes an n-type oxide semiconductor consisting of nanoparticles. 4. The photoelectric conversion element according to claim 3 , wherein the n-type oxide semiconductor includes at least one material selected from the group consisting of titanium oxide, zinc oxide, tin oxide, and niobium oxide.
