Synthesis of Cu2ZnSnS4 nanocrystal ink and its use for solar cells.

Abstract

Cu(2)ZnSnS(4) (CZTS) and Cu(2)ZnSnSe(4) (CZTSe) based solar cells are promising candidates for low cost solar cells due to the natural abundance and low toxicity of the constituent elements. Here, we present the first reported synthesis of colloidal CZTS nanocrystals using a simple solution-phase method. Solar cells fabricated using selenized CZTS nanocrystal inks had a power conversion efficiency of 0.74% under AM1.5G illumination.
