dc.description.abstract |
The two semiconductor layers Cu2ZnSnS4 (CZTS) and CdS were successfully
fabricated using economical, solution-based fabrication techniques. CZTS thin
film fabrication was done by spin coating technique onto soda-lime glass
substrates at rotating speed of 2000 to 6000 rpm. It was found that the optimum
precursor solution temperature is 38

C have shown a band gap in the range of 1.45 to
1.55eV. Cadmium Sulfide (CdS), the n-type semiconductor heterojunction partner
for CZTS was also deposited with good thickness control and uniformity in the
range of 50-100nm range. Chemical bath deposition method was utilized for CdS
thin film fabrication and the CdS thin film with optimum properties was obtained
at the conditions of 40

(30 mins) for the optimization of CdS bandgap. CdS thin film fabricated under
optimum conditions has shown a bandgap range of 2.30eV-2.50eV. Successful
deposition on Fluorine doped Tin Oxide (FTO) glass substrate, reveals a feasible
route to fabricate superstrate type photovoltaic cell. |
