Cover Story: This study presents novel semiconductor thin films based in copper-arsenic-sulfide obtained directly from local raw materials extracted from mines in the Portuguese region of the Iberian Pyrite Belt. The films are deposited via radio frequency magnetron co-sputtering, using a commercial Cu target together with a natural Cu-As-S target. The use of two targets results in stoichiometry gradients within each film, showing a transition from amorphous copper-arsenic-sulfide compounds to crystalline djurleite (Cu31S16). The bandgap values of copper-arsenic-sulfide range between 2.50 and 2.65 eV, indicating a promising application as wide-bandgap semiconductors in third-generation (e.g., multi-junction) photovoltaic devices.
