Design Meets Nature: Tetrahedrite Solar Absorbers

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.
