“…Modication of electrode surface may enhance the electrochemical properties of the electrode for various application such as solar cells, 1,2 supercapacitor, 3 organic light-emitting diodes (OLEDs), 4,5 chemical sensors 6,7 and biological sensors. [8][9][10] Modication of the electrode surface will increase the electrode performance by introducing of interest materials through surface absorption, 11,12 crosslinking agent, 13 covalent bonding, 14 non-covalent bonding 15 or other types of attachment. Therefore, the modication of electrode surface has become critical studies to allow enhancement of electrode properties.…”

“…Although the electrical conductivity, electrocatalytic activity, and chemical stability of Pt are excellent [7], the high price limited its large-scale application in counter electrodes [8]. Therefore, several substitute materials including carbon materials [9][10][11][12][13], conductive polymers [14], and transition metal sulfides [15][16][17][18][19] are explored to replace Pt. Cu 2 ZnSnS 4 (CZTS), as a transition metal sulfides material, has been considered to be a satisfying counter electrode material to replace expensive Pt in DSSCs due to its sufficient catalytic sites in catalyzing the reduction of I 3 − in the electrolyte of DSSCs [20][21][22][23][24][25].…”

The catalytic activity and conductivity of Cu 2 ZnSnS 4 /graphene counter electrode for dye-sensitized solar cells (DSSCs) was balanced using hydrothermal-synthesized kesterite Cu 2 ZnSnS 4 and graphene obtained by product line. It was found that the electrocatalytic activity of Cu 2 ZnSnS 4 /graphene counter electrode was adjustable by balancing its catalytic activity and conductivity using varied weight ratio of graphene in the composited material of Cu 2 ZnSnS 4 /graphene. When the weight percent of graphene was 2% to Cu 2 ZnSnS 4 , the catalytic activity and conductivity of Cu 2 ZnSnS 4 /graphene counter electrode came to the balanced point, resulting in the best electrocatalytic activity. Under the balanced conditions, the dye-sensitized solar cell devices based on Cu 2 ZnSnS 4 /graphene counter electrode show a maximum solar-to-electrical power efficiency of 3.71% (with shortcircuit photocurrent density J sc of 13.24 mA cm −2 , open-circuit photovoltage V oc of 0.63 V, and fill factor FF of 0.44), which is higher than that of unbalanced counter electrode. Although the photovoltaic performance of DSSCs based on Cu 2 ZnSnS 4 / graphene counter electrode was a little lower than that of DSSCs based on platinum (Pt) counter electrode (4.95%), it is believed that Cu 2 ZnSnS 4 /graphene counter electrode would outperform Pt counter electrode by further balancing its catalytic activity and conductivity using higher-quality and more matched Cu 2 ZnSnS 4 and graphene. This strategy to improve the electrocatalytic activity of counter electrode will be helpful for exploring facile synthesis, low-cost, and efficient Cu 2 ZnSnS 4 -based composited counter electrode materials.

The composite material of quaternary kesterite type Cu 2 ZnSnS 4 and reduced graphene oxide (CZTS/RGO) was successfully synthesized by a one-pot hydrothermal synthesis method. When applied as counter electrode materials for dye-sensitized solar cells, it shows better electro-catalytic performance towards reduction of triiodide. The DSSCs based on CZTS/RGO counter electrode shows a maximum solar-to-electrical power efficiency of 3.08%, which is much higher than that of pure CZTS counter electrode (1.41%) and pure RGO counter electrode (1.55%) prepared under the same conditions. The weight percent of GO to CZTS raw material used to synthesize CZTS/RGO is an important factors to affect the photovoltaic performance of DSSCs based on CZTS/RGO counter electrode. It is believed that as-synthesized CZTS/RGO can potentially be used as alternative counter electrode materials to replace the expensive Pt counter electrode, and this one-pot synthetic method will be helpful for exploring facile synthetic route of low-cost and efficient CZTS based composite counter electrode materials.[a] Dr.
