Four-junction, four-terminal stacked solar cell hits 43.9 percent efficiency
• http://www.gizmag.com, By Darren QuickThe multilayer, microscale solar cell was created by North Carolina-based Semprius Inc. and California-based Solar Junction, working in collaboration with a team from the University of Illinois at Urbana-Champaign led by Professor John Rogers. Using Semprius' proprietary high-speed micro transfer printing process high that it says is able to simultaneously produce thousands of stacked microcells with very high yields, the team stacked a triple-junction microcell on top of a single-junction microcell to create a four-junction, four-terminal stacked solar cell.
