Design Meets Nature: Tetrahedrite Solar Absorbers

Computational inverse design and conse-quent experimental results allow for the identifi cation of new tetrahedrite-mineral compositions as promising absorber can-didates in drift-based thin-fi lm solar cells. In device simulations, cell effi ciencies above 20% are modeled with absorber layers as thin as 250 nm. These new com-positions thus open opportunities for re-alization of a new class of high-effi ciency thin-fi lm solar cell. J. Heo , R. Ravichandran , C. F. Reidy , J. ate , T J. F. Wager , D. A.
