Dye-sensitized solar cells with high-performance electrodeposited gold/polyaniline composite counter electrodes

Effects of surface modification of MoS2:TiO2:Pt counter electrodes by argon plasma treatment on photovoltaic performance of dye-sensitized solar cells

“…Furthermore, the current density of the redox peak for MoS 2 :TiO 2 :Pt(I) [MoS 2 :TiO 2 :Pt(II) or MoS 2 :TiO 2 :Pt(III)] CEs is higher than that of the redox peak for MoS 2 :TiO 2 CEs. The cathodic current density at reduction peak is directly proportional to the electrocatalytic ability of the electrode [5]. The significantly enhanced electrocatalytic activity of the MoS 2 :TiO 2 :Pt(III) CE can be attributed not only to the low overpotential loss, but also to the reduction in the value of overpotential.…”

“…Dye-sensitized solar cells (DSSCs) have emerged as attractive candidates for constructing efficient third-generation photoelectrochemical solar cells [1][2][3][4][5][6][7][8][9]. Generally, a DSSC is composed of a dyesensitized TiO 2 photoanode, a redox electrolyte containing iodide/triiodide (I -/I 3 -) redox couple and a counter electrode (CE).…”

“…Generally, a DSSC is composed of a dyesensitized TiO 2 photoanode, a redox electrolyte containing iodide/triiodide (I -/I 3 -) redox couple and a counter electrode (CE). CE is generally employed to collect electrons via the external circuit and speed up the reduction reaction of I 3 -to I -in the redox electrolyte [5][6][7][8][9][10][11][12][13]. The noble platinum (Pt) is usually deposited on a conductive glass substrate as CE material due to its excellent electrical conductivity, electrocatalytic activity, and electrochemical stability [2,3].…”

Facile fabrication of novel silver-polypyrrole-multiwall carbon nanotubes nanocomposite for replacement of platinum in dye-sensitized solar cell

“…Several varieties of low cost materials such as conducting polymers,various carbonous materials,conducting polymers composite, metal sulfides and transition metal carbideshave been servicedto replace the platinum CE. [13][14][15] In recent decades various carbon nanomaterials such as amorphous carbon, carbon nanotubes carbon black, and Graphene/carbon nanotubes composites have been employed as a promising alternative to Pt CE owing to their affordable cost, large electrical conductivity, corrosion resistance, and excellent catalytic activity. [16][17][18][19][20][21][22][23][24] Among them, carbon nanotubes have been widely reported as an efficient alternative platinum CE owing to their extraordinary attractive features, notably high conductivity, fast electron transport and high surface area, but their electro catalytic activity for I 3 − reduction are poor.…”

Nitrogen-doped porous carbon prepared by a facile soft-templating process as low-cost counter electrode for High-performance dye-sensitized solar cells

“…Therefore, much effort has been made to replace Pt in DSCs with low-cost and high-stability alternatives including inorganic metal compound [8][9][10], conducting polymer [11][12][13], and carbonaceous materials [9,14]. Carbon-based materials, such as carbon black [15], porous carbon [16][17][18][19], graphene [20][21][22], and carbon nanotubes [23][24][25], have recently attracted much attention as practical materials for the counter electrode in DSCs because of their low cost, high resistance against corrosion, and good catalytic activity and conductivity.…”
