Due to the availability and low cost of the elements, the semiconductor systems Cu-Sb-Bi-S(e) and Cu-Zn-Sn-S(e) are being studied as sustainable alternatives to the expensive absorber material based on CuIn(Ga)S(e)2. The research is focussed on two main areas: 1) Acquisition of the basic information of the ideal compounds by growth of single...

Thin films of CuSbS2 and Cu3BiS3 were produced by conversion of stacked and co-electroplated metal precursors in the presence of elemental sulfur vapour. The reaction sequences have been studied by ex-situ XRD analysis of the processed samples in order to optimise the sulfurisation parameters for achieving compact layers. For equal processing...

Due to the availability and low cost of the elements, the semiconductor compounds in the system Cu-Sb-Bi-S(e) are being studied as sustainable alternatives to CuIn(Ga)S(e)2 for thin-film photovoltaic applications. The samples have been produced by one-step or multi-step electrodepositions from aqueous solutions followed by chalcogenization of...
