Investigating the Effect of Annealing on the Properties of Cu2SnS3 Thin Films Using Spin Coating | Chapter 10 | Current Approaches in Science and Technology Research Vol. 14

Copper Tin Sulphide is a good material for thin film hetero-junction solar cells because of its electrical and optical properties. It's a p-type ternary direct band gap material with a lot of thin-film solar cell potential. Its components are non-toxic, abundant in the earth's crust, and inexpensive. The purpose of this study is to define the deposition of CTS thin films on soda-lime glass substrates using a jejune sol-gel spin coating technique at different temperatures. Using appropriate characterisation methods to explore their optical, structural, and morphological characteristics, the effect of annealing temperatures on the formation and properties of the films is investigated. According to XRD studies, CTS has a cubic structure. The facet for solar cells is adequate, according to SEM analysis. According to optical quantifications, the energy bandgaps of the films fall from 1.61eV to 1.45eV after annealing. Such energy gap magnitudes are ideal for semiconducting materials employed as an absorber layer in thin film solar cells.
