Potentiostatic pulse plated CZT precursor film from pyrophosphate bath
Fabricated CZTS film from sulfurization of co-electrodeposited CZT precursor film
Kesterite structured CZTS film with secondary phases is observed.
Amount of secondary phases is reduced by increasing the annealing time.
Obtained bandgap of CZTS films is 1.5 eV, suitable for solar cell applications.
