Abstract
A solar cell including a quantum dot and an electron conductor, with a bifunctional ligand disposed between the quantum dot and the electron conductor. The bifunctional ligand molecule may include an electron conductor anchor that bonds to the electron conductor and a first quantum dot anchor that bonds to the quantum dot. A hole conductor such as a conductive polymer may include a second quantum dot anchor. In some instances, the first quantum dot may include selenium.
Claims25
A solar cell comprising:
- an electron conductor layer;
- a quantum dot layer;
- a bifunctional ligand layer coupled to the electron conductor layer and to the quantum dot layer, the bifunctional ligand layer including selenium;
- and
- a hole conductor layer coupled to the quantum dot layer.
A solar cell comprising:
- an electron conductor;
- a quantum dot;
- a selenium-based bifunctional ligand coupled between the electron conductor and the quantum dot;
- and
- a hole conductor coupled to the quantum dot, the hole conductor comprising a sulfur-functionalized thiophene.
A solar cell comprising:
- an electron conductor;
- a quantum dot;
- a bifunctional ligand comprising an electron conductor anchor secured to the electron conductor and a selenium-based quantum dot anchor secured to the quantum dot;
- and
- a sulfur-based hole conductor also secured to the quantum dot.
