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.
Claims13
A solar cell comprising:
- an electron conductor layer;
- a quantum dot layer;
- a bifunctional ligand layer having an electron conductor anchor that bonds to the electron conductor layer and a quantum dot anchor that bonds to a quantum dot layer, the bifunctional ligand layer providing a conduit for electrons that are elected by the quantum dot to travel to the electron conductor layer, the bifunctional ligand layer including selenium;
- and
- a hole conductor layer coupled to the quantum dot layer.
