摘要： A dielectric material layer is formed on a front surface of a photovoltaic device. A patterned PMMA-type-material-including layer is formed on the dielectric material layer, and the pattern is transferred into the top portion of the photovoltaic device to form trenches in which contact structures can be formed. In one embodiment, a blanket PMMA-type-material-including layer is deposited on the dielectric material layer, and is patterned by laser ablation that removes ablated portions of PMMA-type-material. The PMMA-type-material-including layer may also include a dye to enhance absorption of the laser beam. In another embodiment, a blanket PMMA-type-material-including layer may be deposited on the dielectric material layer and mechanically patterned to form channels therein. In yet another embodiment, a patterned PMMA-type-material-including layer is stamped on top of the dielectric material layer.

The graphene film is formed from one or more graphene sheets. The graphene sheets are exposed to a solution having a one-electron oxidant configured to dope the graphene sheets to increase a conductivity thereof, thereby increasing the overall conductivity of the film. The graphene film can be formed prior to the graphene sheets being exposed to the one-electron oxidant solution. Alternatively, the graphene sheets can be exposed to the one-electron oxidant solution prior to the graphene film being formed. A method of fabricating a transparent electrode on a photovoltaic device from a graphene film is also provided.

摘要： A photosensitive monolayer is self-assembled on an oxide surface. The chemical compound of the photosensitive monolayer has three components. A first end group provides covalent bonds with the oxide surface for self assembly on the oxide surface. A photosensitive group that dissociates upon exposure to ultraviolet radiation is linked to the first end group. A second end group linked to the photosensitive group provides hydrophobicity. Upon exposure to the ultraviolet radiation, the dissociated photosensitive group is cleaved and forms a hydrophilic derivative in the exposed region, rendering the exposed region hydrophilic. Carbon nanotubes or nanocrystals applied in an aqueous dispersion are selectively attracted to the hydrophilic exposed region to from electrostatic bonding with the hydrophilic surface of the cleaved photosensitive group.

摘要： The present invention provides a method for the selective placement of carbon nanotubes on a particular surface. In particular, the present invention provides a method in which self-assembled monolayers formed on an unpatterned or patterned metal oxide surface are used to attract or repel carbon nanotubes from a dispersion containing the same. In accordance with the present invention, the carbon nanotubes can be attracted to the self-assembled monolayers so as to be attached to the metal oxide surface, or they can be repelled by the self-assembled monolayers bonding to a predetermined surface other than the metal oxide surface containing the self-assembled monolayers.

摘要： A semiconductor nanowire is coated with a chemical coating layer that selectively attaches to the semiconductor material and which forms a dye in a chemical reaction. The dye layer comprises a material that absorbs electromagnetic radiation. A portion of the absorbed energy induces electronic excitation in the chemical coating layer from which additional free charge carriers are temporarily donated into the semiconductor nanowire. Thus, the conductivity of the semiconductor nanowire increases upon illumination on the dye layer. The semiconductor nanowire, and the resulting dye layer collective operate as a detector for electromagnetic radiation.
