“…6) In 2008, the research team led by H. Zhu, H. Zeng et al, published a paper about using carbon nanotubes (CNTs) to prepare counter electrodes and anthocyanin dye for application to DSSCs, and the acquired solar energy-to-electricity conversion efficiency was 1.46%. 7) In recent years, CNT thin film has attracted the interests of quite a lot of societies and industries. The unique electronic and structural properties of CNTs have prompted researchers to incorporate them as integrative building blocks for solar cells.…”

This study mainly explores the incorporation of counter electrode thin film and extracted natural anthocyanin dye in dye-sensitized solar cells (DSSCs). We adopt single-walled carbon nanotubes (SCNTs), with diameters of 1-2 nm and lengths of 1-20 mm, as well as multi-walled carbon nanotubes (MCNTs), with diameters of 10-30 nm and lengths of 10-15 mm. This study also uses a doctor bade to coat the purified carbon nanotubes on fluorine-doped tin oxide (FTO) conductive glass, so as to form thin film with single layer thickness of around 100 mm. In addition, for preparation of natural dye, anthocyanin dye is extracted from mulberry fruits. The experimental results show that the DSSCs which are incorporated with purified SCNT counter electrode thin film and anthocyanin dye extracted from mulberry fruit can achieve the photoelectric conversion efficiency of 0.672%.

“…Recently, to reduce the production cost of solar devices, a lot of carbon materials are researched to replace platinum electrode [14][15][16][17][18] and got a good performance with carbon materials. However, there is an intrinsic problem of insolubility in most solvents and many groups have tried to solve it in decades [19,20].…”

A Poly (3, 4-ethylenedioxythiophene): polystyrenesulfonate (PEDOT:PSS)/carbon conductive paste was prepared and coated on a conducting FTO glass to construct counter electrode for polymer heterojunction dye-sensitized solar cells (DSSCs). The surface morphology, conductivity, sheet resistance, redox properties and photoelectric properties of carbon electrode were observed respectively by scanning electron microscopy, four-probe tester and CHI660D electrochemical measurement system. The experimental results showed that DSSCs had the best photoelectric properties for PEDOT:PSS/carbon counter electrode annealing at 80°C in vacuum conditions. Using [6, 6]-phenyl-C 61 -butyric acid methyl ester (PCBM)/poly (3-hexylthiophene) (P3HT) heterojunction to replace I -3 =I -redox electrolyte, the overall energy conversion efficiency of the DSSCs with barrier layer reached 4.11% under irradiation of a simulated solar light with a intensity of 100 mW$cm -1 (AM 1.5), which is higher 20% than that of the DSSCs with Pt counter electrode (3.42%). The excellent photoelectric properties, simple preparation procedure and low cost allow the PEDOT:PSS/carbon electrode to be a credible alternative used in DSSCs.

“…Thus, it has been appropriate to use them as a counter electrode in DSSC to replace expensive Pt. 16 When they are used as a working electrode, however, their catalytic property allows the collected electrons at the working electrode to recombine with I 3 À in the electrolyte by the reaction I 3 À þ2e ! 3I À , at the electrolyte/working electrode interface.…”

Cataloged from PDF version of article.Transparent and conductive carbon-based materials are promising for window electrodes in solid-state optoelectronic devices. However, the catalytic activity to redox reaction limits their application as a working electrode in a liquid-type dye-sensitized solar cell (DSSC). In this letter, we propose and demonstrate a transparent carbon nanotubes (CNTs) film as the working electrode in a DSSC containing iodide/triiodide redox couples. This implementation is realized by inhibiting the charge-transfer kinetics at CNT/redox solution interface with an aid of thin titanium oxide film that facilitates the unidirectional flow of electrons in the cell without sacrificing the electrical and optical properties of CNT.
