Simplistic toxic to non-toxic hydrothermal route to synthesize Cu2ZnSnS4 nanoparticles for solar cell applications

摘要: Abstract Solution-synthesized nanostructured Cu 2 ZnSnS 4 (CZTS) has attracted significant attention as a promising candidate for use an efficient and inexpensive photovoltaic energy convertor material. In general, the solution synthesized route involves of toxic explosive chemicals. The current report emphasizes non-toxic surfactant mediated hydrothermal synthesis CZTS NPs (CZTS NPs) without physical chemical properties were studied using X-ray diffraction (XRD), Raman spectroscopy, photoelectron spectroscopy (XPS), transmission electron microscopy (TEM) techniques. XRD results confirmed formation single-phase kesterite NPs. TEM analysis revealed well-dispersed that ∼5–10 nm in size. sodium dodecyl sulfate played key role optical absorption studies had band gap 1.85 eV, which is favorable applications. could be used form ink, to directly coat large area thin film solar cells. Moreover, probable reaction mechanism assisted proposed present report.
