Abstract

A rapid development of solar cells has been observed within recent years. Semiconducting materials based on Cu₂ZnSnS₄ with the kesterite structure offer a promise of low-cost and environmentally friendly solar cells. The energy gap of Cu₂ZnSnS₄, which is about 1.5 eV, can be optimized with addition of organic ligands. We report a method of obtaining kesterite nanopowders with grain diameter of approximately 5 nm via solution synthesis using metal chlorides and sulfur in oleylamine at 230 °C. The ligand exchange for diphenylamine upshifted the value of the bandgap to 2.2 eV, which makes it a promising material for an upper layer in tandem photovoltaic devices.
