Tandem solar cells based on silicon and perovskites have raised high hopes for future high efficiency solar modules. A team has now shown that an ultimate efficiency of 30 percent should be attainable with such tandem cells. They discovered a structurally stable perovskite composition with its band gap tuned to an optimum value of 1.75 eV.
