• In a present study our purpose is to enhance the efficiency of third generation CZTS solar cell. We present a hydrothermal process for the synthesis of Cu2ZnSnS4 (CZTS) nanocrystals straightforward inorganic salts of Cu(II), Zn(II), and Sn(II) and using thiourea as a precursor dissolved in 40 ml deionized water, stir for 3 h and heated at 210 °C. Because of its low cost, non-toxic components, perfect direct band gap as an absorber layer, and higher absorption coefficient, the semiconductor Cu2ZnSnS4 (CZTS) material has attracted significant technological interest in the photovoltaic sector. At 210 °C, kieserite-structured CZTS nanocrystals were created. Wet chemical co-precipitation was used to create Ti3C2 doped CZTS nanocrystals. The CZTS nanocrystals have an optical indirect band gap of 1.47 eV extracted from UV–visible spectra, which is ideal for photovoltaic packages in keeping with the absorption spectrum. XRD peaks of both CZTS and Ti3C2 are quite close to one another, and the results of these peaks are closely matched with relevant prior research. The FTIR spectra do not shows any broad band at any point but having short band at 2120 cm−1. A broad PL band from CZTS was recently found at roughly 490 nm. Successful chemical synthesis of CZTS nanostructures demonstrate the production of affordable, eco-friendly and less toxic nanomaterials that may be used in future solar equipment. •Cu2ZnSnS4/Ti3C2 were prepared by hydrothermal method.•Cu2ZnSnS4 composites were synthesized by varying concentration of Ti3C2.•Cu2ZnSnS4 (95 %) and Ti3C2 (5 %) exhibited enhanced absorption coefficient and reduced band gap of Cu2ZnSnS4 material.•Cu2ZnSnS4 (95 %) and Ti3C2 (5 %) exhibit high efficiency in solar cell.
