Correlation between product purity and process parameters for the synthesis of Cu 2 ZnSnS 4 nanoparticles using microwave irradiation

摘要: Kesterites (CZT(S,Se)4) emerged as a favourable photovoltaic material, leading to solar cell efficiencies high 12.7%. The development of sustainable roll-to-roll printing processes that make use Cu2ZnSnS4 (CZTS) nanoparticle inks requires the proper design synthetic approaches and understanding relation between process parameters product purity. In current paper, we developed this relationship by calculating specific energy factor. A microwave-assisted method operates at atmospheric pressure makes eco-friendly solvents is established. Four solvents, i.e. ethylene glycol (EG), diethylene (di-EG), triethylene (tri-EG) tetraethylene (tet-EG) are compared temperature during reaction assessed two different methods. particular, by-products have been identified, Cu2 − x S hexagonal phase. We show variation such power irradiation, type solvent precursor concentration influences nanoparticles’ sizes (from 12 6 nm) also temperature-time profile which, in turn, can be related phase purity CZTS nanoparticles. results suggest scales with factor providing useful tool rational high-quality
