ABSTRACT:We use graphene oxide (GO) as a “surfactant” to obtain stable colloidal dispersion of carbon nanotubes (CNTs). CNT ﬁlms are subsequently synthesized successfully without the addition of any traditional surfactants. Dye-sensitized solar cells assembled using the resulting CNT ﬁlm as a counter electrode deliver a power conversion efﬁciency up to 5.29%. More importantly, the additional reduced graphene oxide signiﬁcantly increases the electrical conductivity and the catalytic activity of the CNT ﬁlm. The cell performance using a CNT ﬁlm counter electrode (5.29%) reaches 68.70% of that of cells prepared using a platinum ﬁlm counter electrode (7.70%).
