Abstract:
This study introduces a cost-effective hydrothermal method for synthesizing Cu2ZnSnS4 (CZTS) nanoparticles. The synthesis process involves dissolving zinc chloride, tin(II) chloride, copper(I) chloride, and thiourea in deionized water to produce CZTS nanoparticles. The resulting nanoparticles exhibit a phase-pure kesterite structure, confirmed through Raman spectroscopy and X-ray diffraction analysis. Optical and morphological assessments revealed strong absorption in the visible range, with a band gap energy of 1.55 eV. Energy-dispersive X-ray spectroscopy (EDX) confirmed the stoichiometric composition of the nanoparticles. Used as counter electrodes (CE) in dye-sensitized solar cells (DSSCs) under AM 1.0 G light, the CZTS nanoparticles achieved a power conversion efficiency of 2.78%, compared to 3.04% for platinum CEs. These findings suggest that kesterite nanoparticles can serve as a viable, cost-effective alternative to platinum CEs in DSSCs, addressing the issue of platinum scarcity.
