| Popis: | Cd-doping and nanofibrous morphology are proposed to improve the TiO2 performance as photoanode in the dye-sensitized solar cells. Practical results indicate that Cd ions interfered with the crystalline structure of TiO2 nanofibers, causing an increase in the absorption in the visible spectrum, transport of the charges, and reduced re-bonding between the charge carriers in the barrier area between the electrolyte and the working electrode, compared to the un-doped titania nanofibers. It is interesting that a DSSC based on a Cd-doped TiO2 nanofiber working electrode has a double power conversion efficiency (2.945%) compared with the pristine titanium oxide nanofibers-based cell; 1.54%. |
