A collaborative project between the U.S. Department of Energy’s National Renewable Energy Laboratories and researchers from two Swiss centers has tested a range of multi junction cells in tandem configuration, and achieved efficiencies of up to 35.9%.
Though NREL and Berkeley Lab are not specifically mentioned – yet – the cuts at two other labs could signal dim times ahead for these two vital labs for renewable energy research.
Belgian research institute Imec has achieved a conversion efficiency of 23.9% on a perovskite/silicon tandem module measuring 4 square centimeters. This efficiency level, according to Imec, represents the first time such a stacked configuration has outperformed a standalone silicon solar cell.
A study from the University of California and TU Munich in Germany shows that long-term R&D spending played a critical role in achieving cost reductions.
Scientists at the Department of Energy’s SLAC National Accelerator Laboratory have published research revealing unusual atomic motions in perovskite materials exposed to light. Stanford says the discovery could prove crucial to further increasing the efficiency potential for perovskite solar cells.
The Senate Subcommittee on Energy and Water development slammed what it called an “unrealistic” budget from President Trump, and proposed additional funding for agencies Trump planned to gut or eliminate.
The funding is for 48 identified solar projects spanning two SunShot programs designed to advance solar power technologies in the U.S.
