Influence of tartaric acid as the complexing agent on the properties of chemical bath deposited FeSxOy thin films
FeSxOy thin films were deposited on fluorine-tin-oxide (FTO)-coated glass substrate at 75 °C and 3 h deposition time via chemical bath deposition (CBD) from solution containing 100 mM Na2S2O3 and 30 mM FeSO4. The effects of L(+)-tartaric acid (C4H6O6) as the complexing agent under different concentr...

| Summary: | FeSxOy thin films were deposited on fluorine-tin-oxide (FTO)-coated glass substrate at 75 °C and 3 h deposition time via chemical bath deposition (CBD) from solution containing 100 mM Na2S2O3 and 30 mM FeSO4. The effects of L(+)-tartaric acid (C4H6O6) as the complexing agent under different concentration were studied. All the films were crystalline and exhibited n-type photoresponse. The films deposited with complexing agent generally possess less iron and larger oxygen and sulfur contents than those deposited without the agent. The tartaric acid seems capable to reduce or control the thickness, enhance the uniformity, delayed the hematite formation and results in clearer absorption edge. Larger crystallite size and larger optical transmittance were observed for the film deposited with 50 mM tartaric acid. The influence of tartaric acid in FeSxOy thin films can be explained by considering suppression of elemental Fe deposition and enhancement of sulfur reduction. |
