Cu2ZnSnS4 (CZTS) and Cu2ZnSnSe4 (CZTSe) based solar cells are promising candidates for tow 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.
