Effect of Magnesium Incorporation on Solution-Processed Kesterite Solar Cells.

The introduction of the alkaline-earth element Magnesium (Mg) into CuZnSn(S,Se) (CTZSSe) is explored in view of potential photovoltaic applications. CuZnMgSn(S,Se) absorber layers with variable Mg content = 0…1 are deposited using the solution approach with dimethyl sulfoxide solvent followed by annealing in selenium atmosphere. For heavy Mg alloying with = 0.
