The growth in energy devices and the role of supercapacitors are increasingly important in today’s world. Designing an electrode material for supercapacitors using metals that have high performance, superior structure, are eco-friendly, inexpensive and highly abundant is essentially required for commercialization. In this point of view, quaternary chalcogenide Cu2NiSnS4 with fascinating marigold flower like microstructured electrodes are synthesized using different concentrations of citric acid (0, 0.05 M, 0.1 M and 0.2 M) by employing solvothermal method. The electrode materials physicochemical characteristics are deliberated in detail using the basic characterization techniques. The electrochemical studies revealed better electrochemical performances, in particular, Cu2NiSnS4@0.1 M-CA electrode revealed high 1029 F/g specific capacitance at 0.5 A/g current density. Further, it retained 78.65% capacity over 5000 cycles. To prove the practical applicability, a full-cell asymmetric solid-state device is fabricated, and it delivered 41.25 Wh/Kg and 750 Wh/Kg energy and power density at 0.5 A/g. The optimum citric acid added Cu2NiSnS4 electrode is shown to be a promising candidate for supercapacitor applications.

“…This is attributed to that more GO in the one‐pot synthetic system will affect the directly contact of CZTS raw materials, leading to more impurity phase existed in CZTS/RGO, which also caused worse electro‐catalytic performance of CZTS/RGO. Although the photovoltaic performance of as‐prepared counter electrode was lower than previous report, it is reasonable to consider that further optimize the composition and structure of CZTS/RGO counter electrode and balance its catalytic activity and conductivity would exhibit better photovoltaic performance in DSSCs and outperform Pt counter electrode.…”

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.
