If you were to have the cells seperated enough, you could use fresnel lenses to increase the output per cell, although you would then need to add a heat-sink to the back of the cell to avoid frying it. An example of such a thing I found was at:

You could also use mirrors to amplify the output as well, for less of an effect...

Indeed. I've also started scraping old rear projection tv's for their Fresnel lens. Great for cooking and potentially a valuable barter item in the next 15-30 years. Typically you can pick up a 50" lens for $10-$40.
