Síntese e caracterização de filmes finos de kesterita em diferentes substratos

Abstract

This work aims to obtain and characterize thin films and powders of Kesterite, Cu2ZnSnS4 or CZTS, using the methods of Synthesis in a Vacuum Furnace and Drop Casting with a thermal bath in a muffle furnace, using the difference between the furnaces in synthesis efficiency. The material was deposited using three different methodologies: (1) deposition on a microscopy glass plate, (2) dry synthesis under vacuum with solid reagents, and (3) deposition on an FTO (Fluorine Tin Oxide) glass plate. The characterization of the material was carried out using several analytical techniques, including: Uv-Vis (Uv-Visible Spectroscopy), IFTR (Fourier Transform Infrared Spectroscopy), XRD (X-Ray Diffraction), SEM (Scanning Electron Microscopy) and Cyclic Voltammetry. Obtaining this material aimed to continue research involving the development of photovoltaic solar panels (PV), counter electrodes (CE) for electrochemistry and solar thermal collectors.
