Abstract
Carbon nanotubes due to their catalytic properties are a promising alternative to platinum counter electrodes (CE) for dye-sensitized solar cells (DSSC). In this study, counter electrodes were made from double-walled carbon nanotube (DWCNT) ink using the spray printing technique and afterwards thermally treated at temperatures ranging from 120 to 300 °C. Morphology and structure was studied using scanning electron microscopy and Raman spectroscopy. DSSCs were constructed from titanium dioxide photoanodes and DWCNT counter electrodes cured at different temperature conditions. The current-voltage characteristics of DSSCs and their impedance spectra recorded under illumination have been studied and compared. The photoconversion efficiency (PCE) of solar cell reached a maximum value of 4.59% when the carbon layer was thermally treated at 300 °C and is higher than that registered for devices with a standard platinum counter electrode.
