Fabrication of a counter electrode for dye-sensitized solar cells (DSSCs) using a carbon material produced with the organic ligand 2-methyl-8-hydroxyquinolinol (Mq)

Abstract

DSSCs fabricated using a carbon material showed a Jsc, Voc, and η of 11.00 mA cm−2, 0.75 V, and 4.25% respectively.

In situcarbon-supported titanium dioxide (ICS-TiO2) as an electrode material for high performance supercapacitors

“…The intensity ratio of the D and G peaks (I D /I G ) represents the degree of disorder in the carbonaceous materials. [62][63][64][65][66][67][68][69][70][71] The I D /I G ratio for the as-prepared ICS-TiO 2 material is 0.85, which indicates a moderate degree of graphitization and long-range ordering of graphitic layers. Raman spectra demonstrated the presence of the anatase phase of TiO 2 in the ICS-TiO 2 .…”

Sucrose-derived carbon-coated nickel oxide (SDCC-NiO) as an electrode material for supercapacitor applications

“…Compared to the carbon derived from sucrose in previous study, 45 the lower the I D /I G value (0.71) of SDCC-NiO more the graphitization in carbon derived from sucrose after interaction with NiO. [48][49][50][51] SDCC-NiO was covered by carbon derived from sucrose and the size of most of the composites was smaller than those of the parental ones due to the limited crystal growth space between carbon layers and the influence of carbon derived from sucrose on nucleation rate, indicating the composition of carbon and NiO.…”

Carbon coated cobalt oxide (CC-CO3O4) as electrode material for supercapacitor applications

“…37,38 It is noted that there are two remarkable peaks around 1356 and 1598 cm À1 refer to the D-band (arising from the edge or defect sites of carbon) and G band (representing the sp 2 carbon) of the graphitic domain, respectively. [39][40][41][42][43] SEM and TEM were used to characterize the morphology of the CC-CO 3 O 4 as shown in Fig. 2.…”
