RED BANK, N.J., May 8, 2013 /PRNewswire/ -- "Method For
Patterned Doping Of A Semiconductor" and "Solar Cells With
Patterned Antireflective Surfaces" are the titles of two new
provisional patent applications filed by Natcore Technology
Inc. (TSX-V: NXT; NTCXF.PK) with the United States Patent and
Trademark Office.
The first of these inventions relates to a method of using liquid
phase deposition (LPD) as a diffusion barrier layer in a selective
emitter process. The second covers methods for selectively
patterning black silicon by pre-applying specific types of
polymers, then dissolving them away.
The selective emitter is a solar cell design in which regions under
the front contacts are heavily doped to improve the electrical
connection, while the remaining emitter surface is lightly doped to
promote better efficiency. The LPD diffusion barrier provides
manufacturers with an easy route to fabrication of these doping
regions.
Although the selective emitter itself is not a new concept, the
processes covered by these provisional patents should yield high
performing selective emitters at low cost in a novel new way.
The patent filing on patterned antireflection surfaces leverages
a similar approach to enable patterning of Natcore's black silicon
layers. In this approach, the regions under the front
contacts can be kept clear of black silicon, allowing better
contact to the cell.
To help perfect these processes, Natcore has installed a
high-temperature furnace in its Research & Development Center
at Kodak's Eastman Business Park in Rochester, NY, as well as a solar simulator
that would allow them to test cells that are produced in the
lab.
"The selective emitter is the first of our applications
that we feel will be revenue producing," says Chuck Provini, Natcore President and CEO. "Even
though it's not a new concept, we think our scientists will be the
first to get a cost-effective application out of the lab and into
production lines."
