5X Batteries? How About 70,000X Solar Cells?

Matt Shipman of North Carolina State University News Services reports on a connector that could allow stacking solar cells without losing voltage.  This stacking could allow cells to operate at solar concentrations of “70,000 suns worth of energy without losing much voltage as ‘wasted energy’ or heat.”  This could have tremendous implications improving the overall efficiency of solar energy devices and reducing the cost of solar energy production. Stacked solar cells live up to their name, simply being several cells stacked on one another, with their layering leading to up to 45-percent efficiency in converting solar energy into electricity.  So far, the big drawback has been the junctions between cells, which tend to waste the energy from the connected cells as …
