Wrenches....

And with any Fresnel-type lens, the focal length is very critical. Applying
the film directly to the cell would be better than sticking a full sheet
onto the glass since glass thickness will vary between module brands.

Wrenches,

Rick Lewandowski (founder of SunWize) and his team have been making PV
modules with an optical film. See http://www.prismsolar.com/  Prism Solar's
primary advantage is less PV cell material lowers cost.

How Prism Solar differs from SolOptics:
- film is laminated with the cell so it does not get wet,
- holographic material is UV stable and is used in extraterrestrial
applications,
- tests have shown PS holograms degrade less than 0.04% per year compared to
silicon cells at 0.5-1% per year,
- angular and spectral multiplexed holograms result in cooler running cells
and useful light down to 0.25 suns.

Rick has worked several years to get Prism Solar ready for primetime. See
their video and live test results and tell me what you think.

Best regards,
Joel Davidson
