Copper Tin Sulphide is a leading prospect in thin film hetero-junction solar cells owing to its germane electrical and optical properties. It is a ternary direct band gap p -type amalgam with substantial potential significance in thin film solar cells. Its components are innocuous, copious in earth crust and inexpensive. This treatise seeks to delineate the deposition of CTS thin films on soda-lime glass substrate by a jejune sol-gel spin coating technique at distinct temperatures. The upshot of annealing temperatures on the development and properties of the films are examined by exploring their optical, structural, morphological properties using apposite characterization methods. XRD analysis avers genesis of cubic structure of CTS. SEM investigation reported adequate facet for solar cells. The optical quantifications reveals that the gap between the energy bands of the films decline from 1.61eV to 1.45eV after annealing. Suchlike energy gap magnitudes are optimal for semiconducting materials as an imbiber layer of thin film solar cells. [ABSTRACT FROM AUTHOR]
