Abstract: 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.

Abstract: A solar cell is disclosed that may include a quantum dot, an electron conductor, and a bifunctional ligand disposed between the quantum dot and the electron conductor. The bifunctional ligand may include a first anchor group that bonds to the quantum dot and a second anchor group that bonds to the electron conductor. The solar cell may 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 bifunctional ligand and into the electron conductor. The hole conductor may be a p-type polymer.

Abstract: Example solar cells and methods for making and using the same are disclosed. An example solar cell may include an electron conductor layer, a quantum dot layer, a bifunctional ligand layer coupling the electron conductor layer and the quantum dot layer, and a hole conductor layer coupled to the quantum dot layer. The bifunctional ligand layer may include an antibiotic, and in some cases, a cephalosporin-based antibiotic.

Abstract: The design and synthesis of a matrix nanocomposite containing amino carbon nanotubes used as a functionalized sensing layer for carbon dioxide detection by means acoustic wave sensing devices, e.g., SAW/BAW devices. These sensing materials contain a type of amino carbon nanotubes (single walled or multi-walled) and a polymer (or other compounds) which are sensitive to carbon dioxide in the acoustic wave sensing device based gas sensors. The sensitivity of the matrix consisting of the amino carbon nanotubes and a polymer (or other compounds) is ensured by the presence of amino groups which can react at room temperature with CO2 in a reversible process to form carbamates.

Abstract: 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.
