this value to 30% at some point. For the near future, solar cell efficiency enhancements such as a new technology from National Semiconductor could have an impact on solar cells and further out we hope that nanoantennas may complement solar cells to convert...

a combination of solar cells and these nanoantennas could result in a raw energy efficiency of more than double of today’s high-end solar cell range, which is somewhere between 40% and 50% and mass-market solar cells that are just below 20%. Starting with...
