New World Record Achieved In Solar Cell Technology

This news came almost 2 years ago and it is still very significant for our much more green and clean energy production in future.
Solar shingles as a tool for substantially lowering our carbon footprint, are here NOW.
Solar shingles not only lower our carbon footprint, but they make us (our home, business, community) very independent, considering our electricity supply and potential power blackout.

From Science Daily:
(Dec. 7, 2006) — U.S. Department of Energy (DOE) Assistant Secretary for Energy Efficiency and Renewable Energy Alexander Karsner has announced that with DOE funding, a concentrator solar cell produced by Boeing-Spectrolab has recently achieved a world-record conversion efficiency of 40.7 percent, establishing a new milestone in sunlight-to-electricity performance. This breakthrough may lead to systems with an installation cost of only $3 per watt, producing electricity at a cost of 8-10 cents per kilowatt/hour, making solar electricity a more cost-competitive and integral part of our nation's energy mix.
