Columbia, MD - June 18, 2012 - New Energy
Technologies, Inc., developer of see-through solar cells for
generating electricity on glass, today announces an improvement in
its manufacturing technique that should lead to higher speed, lower
costs and greater durability.
Teaming with the US Department of Energy's National Renewable
Energy Laboratory, New Energy Technologies Inc. (OTCQB: NENE) has
developed the use of low-cost materials and a special application
technique that could help optimize the movement of electrons within
the ultra-thin solar cells.
This should increase the amount of electricity produced when New
Energy's see-through SolarWindow™ prototype is exposed to natural
or artificial light.
Importantly, the improvement to the
technology can be executed at ambient pressure and low
temperatures, allowing researchers to avoid the use of materials
that must otherwise be deposited using high temperature vacuum
deposition.
Vacuum deposition is both expensive and time-consuming and,
thus, not practical for high speed and large-scale
applications.
This large-area, R2R and S2S fabrication capability
and improved durability of SolarWindow™ technology are crucial for
production of market-ready electricity-generating coatings on
see-through glass and plastic.
Today's innovation promotes low processing temperatures,
enabling high-speed roll-to-roll (R2R) and sheet-to-sheet (S2S)
manufacturing.
Previously, New Energy, with assistance from University of South
Florida and NREL, developed important improvements to New Energy's
SolarWindow™ technology, capable of generating electricity on
see-through glass.
These improvements include enhancements that address advancing
durability, power performance, and cost-effective manufacturability
- all important to the eventual commercial deployment of New
Energy's SolarWindow™ technology.
Today's announcement marks the latest in a series of technical
accomplishments that Company and NREL research teams have recently
achieved.
"Over the past few months, our researchers have unveiled a
virtually invisible conductive wiring system, which collects and
transports electricity on SolarWindow™ prototypes, and have
fabricated a large area working module, which is more than 14-times
larger than previous organic photovoltaic devices fabricated at
NREL," stated Mr. John A. Conklin, President and CEO of New Energy
Technologies, Inc. "Earlier, we developed our first-ever working
SolarWindow™ prototype using a faster, rapid scale-up process for
applying solution-based coatings.
"Together, these achievements have moved us closer to our
manufacturing, scale-up, durability, and power production goals -
all important factors to advancing our SolarWindow™ technology
towards commercial launch," Conklin added.
To generate electricity on SolarWindow™ prototypes, researchers
creatively layer and arrange unique, ultra-thin see-through solar
cells onto glass. Each of these cells is arranged in a network and
interconnected by way of a virtually invisible grid-like wiring
system.
Within these ultra-thin solar cells, the light-induced movement
of electrons generates electricity. When SolarWindow™ prototypes
are exposed to light, the light's energy prompts electron movement
through specific physical and chemical mechanisms leading to power
generation.
Dr. Scott R. Hammond, Principal Scientist at New Energy
Technologies, Inc., believes the discovery announced today could
also favorably improve durability and shelf-life of the Company's
future SolarWindow™ products.
"NREL scientists have previously published unrelated results
that demonstrate dramatic improvements to the operational and
shelf-life of unprotected (i.e., non-encapsulated) photovoltaic
devices utilizing related materials when subjected to continuous
illumination. No doubt, this is a promising and significant
advancement."
Currently under development for eventual commercial deployment
in the estimated 85 million commercial buildings and homes in
America, SolarWindow™ technology is the subject of ten patent
filings and is the world's first-of-its-kind technology capable of
generating electricity on see-through glass windows.
