Dye Sensitized Solar Cell (DSSC) has been received as a next-generation solar cells. For the commercialization of DSSCs, the reduction of cost for materials and process has been one of the major issues. The development of cheap counter electrode (CE) is a very important prerequisite because the regular CE material is the Pt coated Fluorine doped tin oxide (FTO), which occupies almost half of the device cost. In this work, we developed a novel carbon based CEs by combination of highly conducting carbon nanosheet (CNS) and aqueous processable multiwalled carbon nanotubes (MWCNT). In the present CEs, the CNS mainly contributed as a charge collecting electrodes, while the MWCNT exhibited high electrocatalytic effects for the redox media (I-/I3- in this work). The electrocatalytic activity of the carbon based CEs and the performance of DSSCs using the CEs were investigated. The DSSCs using our carbon based CEs displayed a power conversion efficiency (PCE) of ~ 7%. This result can promise for the development of Pt and FTO free CEs for high performance DSSCs.
