High
Efficiency Nitride Passivated Mono Crystalline Solar Cells
These cells are first quality
and are made of mono crystalline silicon that have been efficiency enhanced with
silicon nitride. Unlike many dealers that are selling factory rejects or cracked
cells, these are premium quality and are currently being used in the manufacture
of many high quality modules. They are among the largest cells that are
available on the market, measuring approximately 5 inches square. Rated output is
approximately .47 volts at an incredible 5.2 Isc amps each, making them perfect for
building your own high powered solar modules. They have been enhanced with the
addition of silicon nitride which boosts efficiency !

These are new high efficiency
monocrystalline nitride passivated satellite grade solar cells that were purchased
at auction from Tecstar Inc.,
a Southern California based manufacturer of solar cells for use
in space based technology such as satellites and the international
space station.
These high quality cells are made from high efficiency
monocrystalline silicon that have been treated with silicon nitride to boost
efficiency. They are round in shape and are approximately
3.5 inches in diameter. They have a short circuit rating of approximately
1.54 amps with and open collector voltage of .58 volts @ 1000 w/m2,
25°C.
What makes these cells unique are their
extreme high efficiency. We tested one of these cells with a DC motor driving a
propeller and was able to power the motor from the light of a two cell
flashlight, which makes them perfect for low light applications !
We contacted a respected solar cell
supplier and was told that these cells would normally sell to the space industry
for $100.00 a piece ! They can wired in series to increase voltage, and in parallel
to increase current. Unlike some dealers that are selling seconds
and low tech import cells, these are U.S. made and are of extremely high
quality.
