Abstract
Copper indium disulfide (CuInS2) thin films as an absorption layer for solar cell and photocatalytic
degradation of organic pollutants, were successfully electrodeposited on the
FTO coated glass substrate using the simple and inexpensive electrodeposition method
and a sulfurization process. The effects of the Cu/In molar ratio, annealing temperature
and kind of Cu2þ precursor (Cu(salen) and Cu(acac)2 as novel Cu2þ precursors) on the
structural and morphological properties of samples were examined. The XRD diffraction
patterns and energy dispersive spectroscopy measurements exhibit that high-quality film
with superior crystalline structure was formed in the presence of Cu(salen) as Cu2þ precursor.
Also, we found that a suitable heat treatment temperature could suppress the CuS
phases and form well-crystallized CIS. As we know, this is the first reported efficiency for
any CuInS2 superstrate solar cell to date that fabricated using Cu(salen) as Cu2þ precursor.
In addition, the photocatalytic degradation of organic dye in the presence of assynthesized
CuInS2 thin films was studied. The as-prepared semiconductor photocatalysts
have a good reusability; it can be successfully reused for 5 times recycling photoactivity
tests.
