An international research team has fabricated a 1 cm2 perovskite-silicon tandem solar cell that utilizes a top cell based on a perovskite absorber integrating inorganic copper(I) thiocyanate (CuSCN).

The scientists aim to replace commonly used hole transport materials like PEDOT:PSS and copper thiocyanate (CuSCN ... an open-circuit voltage of 1.14 mV, a short-circuit current of 19.0 mA ...
