Quantum dot solar cell

摘要

A solar cell (10) is disclosed that may include a quantum dot layer (12), an electron conductor layer (16), and a bifunctional ligand layer (14) disposed between the quantum dot layer (12) and the electron conductor layer (16). The bifunctional ligand layer (14) may include a first anchor group that bonds to the quantum dot layer (12) and a second anchor group that bonds to the electron conductor layer (16). The solar cell (10) may include a hole conductor layer (18) that is configured to reduce the quantum dot layer (12) once the quantum dot layer (12) absorbs a photon and ejects an electron through the bifunctional ligand layer (14) and into the electron conductor layer (16). The hole conductor layer (18) may be a p-type polymer.
