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 3.0 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.
