Sub-micrometer-sized Graphite As a Conducting and Catalytic Counter Electrode for Dye-sensitized Solar Cells
TLDR
DSSCs with submicrometer-sized graphite as a catalyst on fluorine-doped tin oxide TCO showed an energy conversion efficiency greater than 6.0%, which demonstrated that the graphite layer could be used both as a conducting layer and as a catalytic layer.Abstract:
Sub-micrometer-sized colloidal graphite (CG) was tested as a conducting electrode to replace transparent conducting oxide (TCO) electrodes and as a catalytic material to replace platinum (Pt) for I...read more

Platinum nanoparticles/graphene composite catalyst as a novel composite counter electrode for high performance dye-sensitized solar cells
Ming-Yu Yen,Chih-Chun Teng,Min-Chien Hsiao,Po-I Liu,Wen-Pin Chuang,Chen-Chi M. Ma,Chien-Kuo Hsieh,Ming-Chi Tsai,Chuen-Horng Tsai +8 more
TL;DR: In this paper, the authors used a water-ethylene method to prepare a composite material consisting of platinum nanoparticles and graphene and showed that the degree of reduction of graphene was increased by the incorporation of Pt, and in addition, the increased concentration of defects was confirmed by the D/G ratio of the Raman spectra obtained.

Few-layer MoS2 nanosheets coated onto multi-walled carbon nanotubes as a low-cost and highly electrocatalytic counter electrode for dye-sensitized solar cells
TL;DR: In this paper, a nanocomposite of molybdenum disulfide and multi-walled carbon nanotubes (MWCNT@MoS2) was proposed for the first time as a counter electrode (CE) catalyst in dye-sensitized solar cells (DSSCs) to speed up the reduction of triiodide (I3−) to iodide(I−).

Raman Spectrum of Graphite
F. Tuinstra,J. L. Koenig +1 more
TL;DR: Raman spectra are reported from single crystals of graphite and other graphite materials as mentioned in this paper, and the Raman intensity of this band is inversely proportional to the crystallite size and is caused by a breakdown of the k-selection rule.

Electrochemical Impedance Spectroscopic Analysis of Dye-Sensitized Solar Cells
TL;DR: The EIS measurements show that DSC performance variations under prolonged thermal aging result mainly from the decrease in the lifetime of the conduction band electron in the TiO2 film.
