Low temperature phase selective synthesis of Cu(2)ZnSnS(4) quantum dots.

ABSTRACT

The application of indium-free quaternary chalcogenides, such as Cu(2)ZnSnS(4) (CZTS), in photovoltaics has created tremendous interest in recent years. In this paper we develop a method to synthesize high quality CZTS nanoparticles with thermodynamically stable kesterite and wurtzite phases via a simple, one-pot, low-cost solution method.
