SOLAR CELL HAVING SUPPLEMENTARY LIGHT-ABSORBING MATERIAL AND RELATED SYSTEM AND METHOD
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.
