In this work, electrochemical characteristics and optical transmittance of carbon nanotubes (CNTs) counter electrodes which had different amount of CNTs in CNTs slurries were analyzed. Two-step heat treatment processes were applied to achieve well-fabricated CNTs electrode. Three sets of CNTs electrodes and dye-sensitized solar cells (DSSCs) with CNTs counter electrodes were prepared. As the amount of CNTs increased, sheet resistance of CNTs electrode decreased. CNTs electrode with low sheet resistance had low electrochemical impedance and fast redox reaction. On the other hand, in case of CNTs counter electrode with low density of CNTs, performance of the dye-sensitized solar cell was improved due to its high optical transmittance. We found that the transmittance of CNTs counter electrode influence the performance of dye-sensitized solar cells.

“…So far, there are cheaper alternative materials that can rival with Pt in terms of electrocatalytic performance such as nitrides [3], sulfides [4], carbides [5], and carbon allotropes. Various types of carbons that can function well as CE catalysts include graphites, carbon nanotubes, graphenes, reduced graphene oxides, activated carbons, carbon blacks, and biomass-derived charcoals (biochars) [6][7][8][9][10][11][12][13].…”

Carbon derived from hair is interesting because it has good electrocatalytic activity due to the existence of innate heteroatom dopants especially nitrogen and sulfur. In this study, a carbon catalyst containing high nitrogen contents (9.47 at.%) was fabricated without using any harsh chemicals. Moreover, the carbonization temperature was only 700°C. Carbonized hair/ PEDOT:PSS composites (C x P) with varied carbon contents from x = 0.2 to 0.8 g were tested as a counter electrode (CE) for a dye-sensitized solar cell (DSSC). This type of DSSC CE has scarcely been investigated. A DSSC with a C 0.6 P CE provides the best efficiency (6.54 ± 0.11%) among all composite CEs because it has a high fill factor (FF) and a high short-circuit current density (J sc ). The efficiency of DSSC with C 0.6 P CE is lower than Pt's (7.29 ± 0.01%) since the Pt-based DSSC has higher FF and J sc values. However, C 0.6 P is still promising as a DSSC CE since it is more cost-effective than Pt.
