Journal of Electronic Materials > 2019 > 48 > 12 > 8254-8260

In the electrodeposition-anneal processes, the as-deposited film presents a deficiency of S which makes sulfurization inevitable. In this paper, an electrolyte was used for elaborating Cu₂ZnSnS₄ thin films with free annealing sulfurization onto indium-doped tin oxide-coated glass substrates for solar cell applications. For a one-step elaboration of CZTS thin films, a potentiostatic process has been...
