Abstract
A solar cell including a quantum dot, an electron conductor, and a conjugated bridge molecule disposed between the quantum dot and the electron conductor. The conjugated bridge molecule may include a quantum dot anchor that bonds to the quantum dot and an electron conductor anchor that bonds to the electron conductor. In some instances, the quantum dot anchor and/or the electron conductor anchor may independently include two anchoring moieties that can form ring structures with the quantum dot and/or the electron conductor. The solar cell may further include a hole conductor that is configured to reduce the quantum dot once the quantum dot absorbs a photon and ejects an electron through the conjugated bridge molecule and into the electron conductor.
