Abstract

We consider Carbon Nanotube (CNTs) counter electrode as alternative material to Platinum counter electrode for dye sensitized solar cells (DSSCs). Also, CNT counter electrodes having different visible light transmittance were prepared on fluorine-doped tin oxide (FTO) glass substrates by spray coating method. Microstructural images show that there are CNT-tangled layers coated on FTO glass substrates. Using such CNT counter electrodes and screen printed TiO₂ electrodes, DSSCs were assembled and its I-V characteristics have been studied and compared. Light energy conversion efficiency of DSSCs increased with decreasing in light transmittance of CNT counter electrode. Our result shows that CNT counter electrode is compatible to Pt counter electrode.
