Fabrication of low cost kesterite Cu₂ZnSnS₄(CZTS) thin films as counter-electrode for dye sensitised solar cells (DSSCs)

Cu2ZnSnS4, a Fascinating Counter Electrode for TiO2‐Free Dye‐Sensitized Solar Cells

“…In particular, sulfide‐based CEs have the eminence in facile preparation, better chemical stability, and excellent electrocatalytic property compared to the other alternative CEs [11–13] . Recently, using naturally abundant element derived a quaternary semiconductor Cu 2 ZnSnS 4 (CZTS) is withdrawn much attention due to its superior p‐type electrochemical properties such as high‐hole concentration (∼1.2×10 15 –3.1×10 20 cm −3 ) [14–17] …”

Jet nebulizer-spray coated CZTS film as Pt-free electrocatalyst in photoelectrocatalytic fuel cells

“…Among the available Pt-free electrocatalyst materials, transition metal oxides, sulphides, nitrides and carbides showed promising electrocatalytic performance in DSSCs. [10][11][12][13][14] In addition, the quaternary semiconductor CZTS geared notable attention in DSSCs owing to less toxic, earth abundance, [15][16][17][18] and high hole concentration [19] of ~1.2×10 15 to 3.1×10 20 cm -3 . Digraskar et al [20] demonstrated the feasibility of CZTS electrocatalyst in powder form toward water reduction into hydrogen fuel.…”

“…The CZTS films can be directly formed on substrates or deposited from the presynthesised nanocrystals. The pre-synthesised colloidal CZTS nanocrystals or inks were transformed onto conducting substrates by spin coating, [15,16] or spray coating [17]. The hydrothermal/solvothermaldeposition, [18,24]electrospun, [25,26] spray coating, [27] electrodeposition, [28,29] sputtering, [23] and pulsed laser deposition [24] methods have been used for direct deposition of CZTS onto substrates.…”

Jet-nebulizer-spray coated copper zinc tin sulphide film for low cost platinum-free electrocatalyst in solar cells

“…In particular, sulphide based electrocatalysts have the merits in easy synthesis, chemical stability, and excellent electrocatalytic property [4][5][6]. Recently, the quaternary semiconductor CZTS perceived profound attention as the Pt-free electrocatalyst in DSSCs owing to its abundance, low toxicity [7][8][9][10], and high hole concentration [11] of ~1.2×10 15 to 3.1×10 20 cm -3 providing high p-type electrical conductivity. This may anticipate high appealing class of electron-driven catalyst materials in electrochemical reduction reaction at DSSCs.…”
