Investigation of carbon nanotubes decorated with cobalt sulfides of different phases as nanocomposite catalysts in dye-sensitized solar cells

Review on transition metal compounds based counter electrode for dye-sensitized solar cells

“…The DSCs using the NiS/MWCNTs/Ti CE achieved a PCE of 7.90%, much higher than the counterparts with the MWC-NTs/Ti CE (1.53%), NiS/Ti CE (7.07%) as well as Pt/Ti CE (6.36%). Moreover, the binary sulfides CEs of Mo 2 S/C, CoS/MWCNTs, and WS 2 /MWCNTs have also been applied in DSCs and all of the binary sulfides performed better than the pristine sulfides [79][80][81][82] . Based on a binary composite of MWCNTs/CoS 1.097 , they also synthesized ternary composite of PANI/MWCNTs/CoS, and the PCE of the DSCs using this ternary sulfide CE increased from 5.54% to 7.02% [83] .…”

Counter electrode materials based on carbon nanotubes for dye-sensitized solar cells

“…A promising PCE of 8.02%, far higher than that obtained by using a Pt based CE (6.49%), was achieved because of high catalytic activity at the electrode-electrolyte interface. Tai et al [208] synthesized NCs constituted of carbon nanotubes and cobalt sulfide in two different forms, i.e. CNT@Co9S8 and CNT@CoS1.097.…”

Carbonaceous materials as substitutes for conventional dye-sensitized solar cell counter electrodes

“…However, it was proved that the same composition of CNT@CoS 1.097 potentially can result in a promise DSSC. 79 The structural features as well as performance of a non-polymerized composed electrode, (which was fabricated by spray-coating followed by annealing under a N2 atmosphere) were measured. X-ray diffraction characterization revealed that the crystalline CoS 1.097 transferred to the form of Co 9 S 8 which possesses higher electrochemical activity.…”
