Nano-Patterned Active Layers Formed By Nano-Imprint Lithography

View page
US Patent:
2010009, Apr 15, 2010
Filed:
Oct 13, 2009
Appl. No.:
12/578286
Inventors:
Fen Wan - Austin TX,
Frank Y. Xu - Round Rock TX,
Sidlgata V. Sreenivasan - Austin TX,
Shuqiang Yang - Austin TX,
Assignee:
MOLECULAR IMPRINTS, INC. - Austin TX
BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEM - Austin TX
International Classification:
H01L 23/50
H01L 21/3205
US Classification:
257749, 438665, 257E23079, 257E21299
Abstract:
Patterned active layers formed by nano-imprint lithography for use in devices such as photovoltaic cells and hybrid solar cells. One such photovoltaic cell includes a first electrode and a first electrically conductive layer electrically coupled to the first electrode. The first conductive layer has a multiplicity of protrusions and recesses formed by a nano-imprint lithography process. A second electrically conductive layer substantially fills the recesses and covers the protrusions of the first conductive layer, and a second electrode is electrically coupled to the second conductive layer. A circuit electrically connects the first electrode and the second electrode.

Assignee:
MOLECULAR IMPRINTS, INC. - Austin TX
BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEM - Austin TX
International Classification:
H01L 21/302
US Classification:
438694, 438689, 257E21214
Abstract:
Methods for creating nano-shaped patterns are described. This approach may be used to directly pattern substrates and/or create imprint lithography molds that may be subsequently used to directly replicate nano-shaped patterns into other substrates in a high throughput process.

Assignee:
MOLECULAR IMPRINTS, INC. - Austin TX
BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEM - Austin TX
International Classification:
H01L 31/0352
US Classification:

US Patent:
2011004, Mar 3, 2011
Filed:
Aug 17, 2010
Appl. No.:
12/857816
Inventors:
Shuqiang Yang - Austin TX,
Sidlgata V. Sreenivasan - Austin TX,
Frank Y. Xu - Round Rock TX,
Assignee:
MOLECULAR IMPRINTS, INC. - Austin TX
BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEM - Austin TX
International Classification:
H01L 31/0352
H01L 31/105
H01L 31/18
US Classification:
136255, 136256, 438 71, 257E31038, 257E31061
Abstract:
Inorganic solar cells having a nano-patterned p-n or p-i-n junction to reduce electron and hole travel distance to the separation interface to be less than the magnitude of the drift length or diffusion length, and meanwhile to maintain adequate active material to absorb photons. Formation of the inorganic solar cells may include one or more nano-lithography steps.

Functional Nanoparticles

US Patent:
2011004, Mar 3, 2011
Filed:
Aug 11, 2010
Appl. No.:
12/854359
Inventors:
Sidlgata V. Sreenivasan - Austin TX,
Shuqiang Yang - Austin TX,
Frank Y. Xu - Round Rock TX,
Vikramjit Singh - Austin TX,
Assignee:
BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEM - Austin TX
MOLECULAR IMPRINTS, INC. - Austin TX
International Classification:
B29C 59/16
B29C 59/02
US Classification:
216 40, 264293, 264447
Abstract:
Functional nanoparticles may be formed using at least one nano-lithography step. In one embodiment, sacrificial material may be patterned on a multi-layer substrate using an imprint lithography system. The pattern may be further etched into the multi-layer substrate. Functional material may then be deposited on multi-layer substrate and solidified. At least a portion of the functional material may then be removed to provide a crown surface exposing pillars. Pillars may be removed from multi-layer substrate forming functional nanoparticles.

Solar Cell Fabrication By Nanoimprint Lithography

US Patent:
2011018, Jul 28, 2011
Filed:
Jan 28, 2011
Appl. No.:
13/016006

Assignee:
MOLECULAR IMPRINTS, INC. - Austin TX
International Classification:
H01L 31/02
H01L 31/0232
US Classification:
136252, 438 72, 257E31127
Abstract:
Fabricating a solar cell stack includes forming a nanopatterned polymeric layer on a first surface of a silicon wafer and etching the first surface of the silicon wafer to transfer a pattern of the nanopatterned polymeric layer to the first surface of the silicon wafer. A layer of reflective electrode material is formed on a second surface of the silicon wafer. The nanopatterned first surface of the silicon wafer undergoes a buffered oxide etching. After the buffered oxide etching, the nanopatterned first surface of the silicon wafer is treated to decrease a contact angle of water on the nanopatterned first surface. Electron donor material is deposited on the nanopatterned first surface of the silicon wafer to form an electron donor layer, and a transparent electrode material is deposited on the electron donor layer to form a transparent electrode layer on the electron donor layer.
