Abstract:
This thesis is devoted to the development of a relatively new, rapidly
developing quaternary semiconducting material (viz., Cu2ZnSnS4) used for
photovoltaic applications. This semiconductor, commonly known as CZTS, is
closely related to a family of materials that have been used for solar cell
applications. It is a compound semiconductor made of copper, zinc, tin and
sulfur, which are sufficiently abundant elements; none of them is harmful to the
environment even at large scale usage. Aim of this study is to fabricate CZTS
solar cells through chemical spray pyrolysis (CSP) technique. At first the
influence of various spray parameters like substrate temperature, spray rate,
precursor ratio etc. on the opto-electronic properties of CZTS films will be
studied in detail. Then the fabrication of CZTS/In2S3 hetero junctions and
various ways to improve the performance parameters will be tried
