The counter-electrodes were prepared on fluorine-doped tin oxide glass substrates by the screen printing technique from pastes of carbon nanotubes and organic binder. The solar cells were assembled from carbon nanotubes counter-electrodes and screen printed anodes made from titanium dioxide. The cells produced with DWCNTs, SWCNTs or MWCNTs have overall conversion efficiencies of 8.0%, 7.6% and 7.1%, respectively. Electrochemical impedance spectroscopy measurements revealed that DWCNTs displayed the highest catalytic activity for the reduction of tri-iodide ions. The large surface area and superior chemical stability of the DWCNTs facilitated the electron-transfer kinetics at the interface between counter-electrode and electrolyte and yielded the lowest transfer resistance, thereby improving the photovoltaic activity. A short-term stability test at moderate conditions confirmed the robustness of solar cells based on the use of DWCNTs, SWCNTs or MWCNTs. Figure Double-wall carbon nanotubes, single-wall carbon nanotubes and multi-wall carbon nanotubes have been investigated as an alternative for platinum in counter-electrodes for dye-sensitized solar cells (DSCs). The carbon nanotubes (CNTs) based DSCs exhibit efficiency high up to 8.0% and are comparable to the Pt based DSCs prepared in the same condition. The CNTs based DSCs have demonstrated a good stability.
