Thin films of gallium arsenide appear to reduce energy loss in stacked solar cells

Researchers at North Carolina State University have developed a new system for strengthening the connections between stacked solar cells which could improve the overall efficiency of concentrated photovoltaic technology and reduce the cost of solar energy production. The hardened connections could theoretically enable these cells to operate at concentrations of up to 70,000 suns while minimizing wasted energy. Stacked solar cells are made up from several solar cells that are stacked one on top of…
