Abstract:
This study reports the fabrication and
characterization of Cu2ZnSnS4 (CZTS) thin films which is
inexpensive and environmental friendly photovoltaic (PV)
material using solution based method. The CZTS thin films were
coated on soda lime glass substrates using spray pyrolysis and
spin coating methods. The thickness variation, electrical
properties and optical properties of the films were determined
for different numbers of coatings. The optical band gap energy of
the prepared films was within the range of 1.5eV to 2.07eV. A set
of prepared CZTS films on glass substrates were subjected to an
annealing process in a normal atmospheric environment to
obtain better crystalline properties [2]
