Single Step Synthesis of Cu2ZnSnS4 by Microwave Combustion Method

We report a novel single step process to synthesize Cu2ZnSnS4 nanopowder. Our novel approach is based on combustion method assisted with microwave irradiation. The obtained results showed that the precursors can be quickly decomposed in the microwave field to form Cu2ZnSnS4 nanopowder. The effects of fuel and microwave power on structures and properties of the nanopowder were investigated thoroughly by Raman spectroscopy. This synthesis process is promising for large scale fabrication of light absorbing materials for photovoltaic devices because it is facile, low cost, non-vacuum, single step and time saving.
