Electronic Gate Enhancement Of Schottky Junction Solar Cells
View pageUS Patent:
20120312371, Dec 13, 2012
Filed:
Apr 27, 2011
Appl. No.:
13/580205
Inventors:
Andrew Gabriel Rinzler - Newberry FL, US
Pooja Wadhwa - Chandler AZ, US

International Classification:
H01L 31/0224
US Classification:
136256
Abstract:
Various systems and methods are provided for Schottky junction solar cells. In one embodiment, a solar cell includes a mesh layer formed on a semiconductor layer and an ionic layer formed on the mesh layer. The ionic layer seeps through the mesh layer and directly contacts the semiconductor layer. In another embodiment, a solar cell includes a first mesh layer formed on a semiconductor layer, a first metallization layer coupled to the first mesh layer, a second high surface area electrically conducting electrode coupled to the first metallization layer by a gate voltage, and an ionic layer in electrical communication with the first mesh layer and the second high surface area electrically conducting electrode. In another embodiment, a solar cell includes a grid layer formed on a semiconductor layer and an ionic layer in electrical communication with the grid layer and the semiconductor layer.

Abstract:
A degradable polymeric nanotube (NT) dispersant comprises a multiplicity of NT associative groups that are connected to a polymer backbone by a linking group where there are cleavable groups within the polymer backbone and/or the linking groups such that on a directed change of conditions, bond breaking of the cleavable groups results in residues from the degradable polymeric NT dispersant in a manner where the associative groups are uncoupled from other associative groups, rendering the associative groups monomelic in nature. The degradable polymeric nanotube (NT) dispersant can be combined with carbon NTs to form a NT dispersion that can be deposited to form a NT film, or other structure, by air brushing, electrostatic spraying, ultrasonic spraying, ink-jet printing, roll-to-roll coating, or dip coating. The deposition can render a NT film that is of a uniform thickness or is patterned with various thicknesses. Upon deposition of the film, the degradable polymeric nanotube (NT) dispersant can be cleaved and the cleavage residues removed from the film to yield a film where contact between NTs is unencumbered by dispersants, resulting in highly conductive NT films.
