Everyone focuses on the LEDs with EFOI, and with good reason, as that's the major part of their business right now. But we often tend to forget about a little ace in the hole that they might have in the solar field.
From the November 10-Q:
"Our development of solar technology continues through our role in the United States Government’s Very High Efficiency Solar Cell (“VHESC”) Consortium sponsored by the Defense Advanced Research Projects Agency (“DARPA”). The goal of the VHESC project is to develop a 40% or greater efficient solar cell for United States military applications, which would also ultimately become available to the public for commercial application."
They have received a couple of grants for this research over the past few of years, and it continues to move forward, albeit mostly out of the limelight.
In the August 2010 cc, the CEO said, "VHESC is in the phase 3 commercialization stage. This
means that the science and art has more or less been perfected and now it’s how do we produce it quickly and cost effectively."
He talks about the technology in some detail in that call as well (transcript filed with 8-K on 8/23/10).
In any event, solar at 40% efficiency is a Big Deal. Current solar cells are only 10-15% efficient. Of course, a lot of other people are trying to do this as well. But the fact remains that EFOI has a pretty good iron in the fire here.
Just wanted to mention this, as I had really forgotten all about it until a few days ago myself.
