Resumo(s)
Titanium films have been deposited on stainless steel metal sheets using dc magnetron sputtering technique
at different substrate temperatures. The structure of the titanium films strongly depend on the
substrate temperature. The titanium film deposited at the substrate temperature lower than 300 ◦C has a
loose flat sheet grains structure and the titanium film prepared at the substrate temperature higher than
500 ◦C has a dense nubby grains structure. The DSSC assembled using stainless steel sheet coated with
titanium film deposited at high substrate temperature has a low charge transfer resistance in the TiO2/Ti
interface and results in a high conversion efficiency. The DSSC assembled using stainless steel sheet
coated with titanium film deposited at temperature higher than 500 ◦C has higher conversion efficiency
than that assembled using titanium metal sheet as the substrate. The maximum conversion efficiency,
2.26% is obtained for DSSC assembled using stainless steel sheet coated with titanium film deposited at
700 ◦C substrate temperature, which is about 70% of the conversion efficiency of the FTO reference cell
used in this study.
