ABSTRACT
Advances in technologies and modernization of the society have influenced the energy demand directly. Increase in energy demand in upcoming years will be very challenging because the consumption of fuel to achieve the energy demand will not be that much promising, since it would be getting vanished very soon. The alternative source which can help to achieve this demand could be solar energy. Solar cell is ought to be the finest application of solar energy. The chalcogenide based absorber materials for thin film solar cells (TFSC) have gained more attention in recent years. However among all the absorber materials the copper zinc tin sulfide (CZTS) found to be an efficient option. It is earth abundant material and relatively benign. CZTS is a p-type semiconducting material possess optical band gap of 1.5 eV, high absorbance coefficient 104 cm–1. In this work, formation of CZTS thin film is done by electrodeposition technique in a single step with glycine complexing agent. Different concentration of glycine for the development of CZTS thin film is studied. Analysis of obtained this films were characterized by adopting various techniques.
