Abstract

The [Formula: see text] (CZTS) thin film is a photovoltaics material with excellent photoelectric properties and has good potential applications. The CZTS thin films with different spin-coated layers and sulfurized temperatures were successfully prepared by a sol–gel spin-coating technique. The relationships of microstructure, surface morphology and processing parameters were studied using XRD, SEM and EDS. The results indicate that the grain size of the sample sulfurized at [Formula: see text]C was larger than that of the sample sulfurized at [Formula: see text]C. With increasing layers of spin, coatings, the films showed better crystalline structure. The sulfureted CZTS thin films prepared by six spin-coating possess uniform elemental distribution.
