-Bernard Sater Inventor & Founder
PhotoVolt, Inc. was formed to commercialize a unique
high performance solar cell technology in the emerging,
multibillion dollar global PV market, which is growing
at a rapid rate of 35% a year.
Our patented Vertical Multi-Junction (VMJ™) solar cell
is fully developed and market ready. VMJ cells will
provide the technical performance and economic
breakthroughs that are needed to make photovoltaic power
systems that are cost-competitive with traditional
fossil-fuel sources of electricity.
Producing a "disruptive technology" -- high performance
solar cells that alter the competitive dynamics in the
photovoltaic market.
PhotoVolt's VMJ Cell

VMJ Cells Field
Testing
-
Average sales price of
existing PV today is over $5/Watt.
Systems based on PhotoVolt's
VMJ cell technology can be installed at
under $2/Watt in high volume.
-
This will drive significant growth in the
PV market, by making it more cost-competitive against
conventional sources of electricity.

"The VMJ cell inherently has very attractive features
in terms of potential high efficiencies and lost cost,
high volume manufacturability"
--Dr. Chandra Goradia, Cleveland State University
My research has shown that the VMJ cell is potentially
as efficient as any other silicon device presently being
manufactured or proposed"
--Dr. Jeffery L. Gray, Purdue University
