摘要:
Solar cells and solar cell assemblies that may be tuned for greater sensitivity to particular ranges of energy within the electromagnetic spectrum. In some instances, a solar cell may include a tunable electron conductor that permits greater choices in quantum dots, thereby providing solar cells that can be constructed to utilize a larger fraction of the solar spectrum. In some cases, the electron conductor may include group III nitride-based materials. A solar cell assembly is also disclosed that may include a first quantum dot solar cell and a second quantum dot solar cell. The first and second quantum dot solar cells may be tuned for differing portions of the electromagnetic spectrum.

A solar cell may include a light sensitive molecule such as a hyperpolarizable molecule. In one example, a solar cell may include a layer of hyperpolarizable molecules disposed between a p-type electrode and an n-type electrode. In some cases, at least some of the hyperpolarizable molecules may include an electron donating group that is bonded or otherwise linked to the n-type electrode as well as an electron accepting group that is bonded or otherwise linked to the p-type electrode. In some instances, at least some of the hyperpolarizable molecules may include an electron donating group that is bonded or otherwise linked to the p-type electrode as well as an electron accepting group that is bonded or otherwise linked to the n-type electrode.
