Optical constants of Cu₂ZnSnS₄ thin films formed using thermal annealing of
pre-deposited layers of copper, zinc and tin sulphides on glass substrates at different
temperatures and ambient atmosphere were determined. It has been shown that films
grown at lower temperatures have the tetragonal structure of kesterite, and the
corresponding value of the optical band gap is 1.47 eV.
