It works best with Semprius' solar cell module. The North Carolina-based company utilizes a breakthrough micro-printing process to produce the solar cells en masse and load them onto specially designed large arrays to collect power from the sun.

John Rogers, a materials science professor at the University of Illinois, pioneered the printing process and in 2005 founded Semprius.

Utilizing Solar Junction's raw materials, Semprius' manufacturing technology creates the Formula One car of solar cells.

The printing process allows Semprius to print Solar Junction's cells at a size no larger than a dot from a pen, the world's smallest solar cell. This is good for a few reasons.

First, it allows it to harness the power of 1,100 suns, at 33.9 percent efficiency, by concentrating radiation into one tiny spot.
