An international team led by the U.S. National Renewable Energy Laboratory (NREL) has used ionic salt for the electron transport layer of a perovskite solar cell to improve device stability and performance. Test results showed a 26% power conversion efficiency with 2% degradation after 2,100 hours of 1-sun operation at 65 C.| pv magazine International
Techno-economic analysis conducted by NREL researchers has shown how perovskite-silicon tandem solar modules could currently hardly compete in cost with incumbent PV panels. Production costs for U.S.-made tandem products were found to range between $0.29/W and $0.42/W, with module efficiencies ranging from 25% to 30%.| pv magazine International
