Abstract

We demonstrate the fabrication of dye sensitized solar cells using multiwall carbon nanotube (MWNT) sheets as a counter electrode with catalytic activity optimized by layering as an alternative to platinum deposited on fluorinated tin oxide (FTO). The sheets are drawn directly from a highly aligned forest of MWNTs grown on silicon by chemical vapor deposition. We used different number of MWNT layers on the FTO and pure glass. Cell performance was found to vary with the number of MWNT sheets. When using of 10 or more layers we can substitute the FTO with platinum catalytic particles.
