Imec has achieved  a record result for its 4-terminal Perovskite/silicon tandem photovoltaic cell. With a power conversion efficiency of 27.1%. The imec  cell beats the most efficient standalone silicon solar cell. Further careful engineering of the Perovskite material will bring efficiencies over 30% in reach. Perovskite microcrystals are a promising material system to make high-performance ...
