I couldn’t say with certainty, but this sure seems like it could be. This is obviously not ready for prime time (three years from serious production), but it is on the short horizon and if the claims bear out this tech completely alters the solar energy playing field.
From the link:
A startup company hopes to bring down the cost of generating power with concentrated sunlight by using microscale solar cells that can utilize twice as much light as other panels, without the need for expensive optics or cooling systems. Panels made from the tiny cells, which the Durham, NC-based company Semprius developed using a novel microprinting technology, also offer significant savings on materials costs. In late January, the company announced a joint agreement with Siemens to develop demonstration systems based on its technology. Semprius plans to begin volume production of the modules in 2013.
Microcell: The solar cells made by Semprius are 600 micrometers on each side and can be combined with high-power optics. The cell itself (the black square at center) is mounted atop a ceramic base with electrical contacts on each side.
