Nature World News: Researchers have developed a method for improving the connections between stacked solar cells that allows for the greater overall efficiency of the solar energy devices.
Developed by scientists from North Carolina State University, the new technique allows these cells to operate at solar concentrations of 70,000 suns worth of energy while minimizing the amount of voltage lost as "wasted energy," or heat.
Stacked solar cells represent the most efficient cells on the market, converting up to...
