The special lab produced solar cells are struggling to get to 40% effiency.

I'm talking about something I saw on the discovery channel a while back. They managed to achieve 80% efficiency but were having to manually align the crystals under a microscope. We're talking about several thousand dollars per square inch.

There is also full spectrum solar cells which produce in the 70% range using Indium Gallium Nitride. Production cost should be near that of current InGaN.

If the process described in this article could be applied to the InGaN full spectrum cells, cost would be small, efficiency would be high, and mass production would be a breeze.

I’d like to see that show, usual suspects (wiki etc.) are still showing the record holder in the low 40’s.
