The influence of the elemental composition of CuZnSn coatings deposited by electrodeposition on the formation of the Cu2ZnSnSe4 crystal structure following a selenisation process was investigated using X-ray diffraction, scanning electron microscopy and Raman spectroscopy. This study showed that the optimum alloy ratio to achieve the Cu2ZnSnSe4 crystal without impurity phases was in the range of 0.37–0.50 for Cu/(Zn+Sn) and 2.5–4 for Zn/Sn.
