Italian researchers have added graphene to the titanium dioxide electron selective layer used in a perovskite cell to increase chemical stability. The two-terminal cell was made by stacking two sub-cells which were fabricated and optimized separately.Researchers from two Italian institutions claim to have developed a two-terminal tandem perovskite-silicon solar cell with a conversion efficiency of more than 26%. Described in the paper Mechanically Stacked, Two-Terminal Graphene-Based Perovskite/Silicon Tandem Solar Cell with Efficiency over 26%, published in Joule, the cell is said to offer the ...Den vollständigen Artikel lesen ...
