CuSbS thin films and solar cells produced from Cu/Sb/Cu stacks via sulfurization.

Phase-pure crystalline chalcostibite (CuSbS) thin films were prepared by depositing Cu/Sb/Cu metal stacks using a thermal evaporation method, followed by sulfurization at 400  C and 430  C for different durations. The investigation revealed the formation of a dominant orthorhombic CuSbS phase accompanied by a minor SbS phase in the film stacks sulfurized at 400  C for 10-60 min. Extending the reaction time to 90 min triggered a decrease in the SbS phase and the emergence of an additional famatinite (CuSbS) phase alongside the dominant CuSbS phase.
