摘要： 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.

摘要： A solar cell includes an electron conductor, a plurality of quantum dots on a surface of the electron conductor forming a quantum dot layer, and a supplemental light-absorbing material in one or more gaps in the quantum dot layer. The supplemental light-absorbing material is capable of absorbing light that passes through the one or more gaps in the quantum dot layer and converting the absorbed light into holes and electrons. The supplemental light-absorbing material may also inhibit a hole conductor from coming into contact with the electron conductor. The supplemental light-absorbing material could include one or more polymers, semiconductors, fluorophores, metal particles, nanowires, nanotubes, and nanoparticles. The supplemental light-absorbing material could also include one or more supplementary quantum dots attached to the electron conductor through one or more linkers, where electrons generated by the one or more supplementary quantum dots are transferred to the electron conductor through the one or more linkers.

摘要： An illustrative solar cell may include an electron conductor, an absorber, a hole conductor, and one or more other layers that help reduce interfacial charge recombination within the solar cell for improved solar cell efficiency. In one example, an electron inhibiting/hole transporting layer is provided that blocks or at least substantially inhibits movement of electrons that may otherwise move from within the absorber and/or electron conductor into the hole conductor of the solar cell, while permitting holes to travel from the absorber to the hole conductor. In some cases, the electron inhibiting/hole transporting layer may be transparent or substantially transparent to incident light so that the incident light may reach the absorber material.
