Inverted perovskite solar cell based on ionic salt achieves 26% efficiency

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. [Lire plus…]
