Computational inverse design and consequent experimental results allow for the identification of new tetrahedrite‐mineral compositions as promising absorber candidates in drift‐based thin‐film solar cells. In device simulations, cell efficiencies above 20% are modeled with absorber layers as thin as 250 nm. These new compositions thus open opportunities for realization of a new class of high‐efficiency thin‐film solar cell.
