Cation/Anion Substitution in Cu₂ZnSnS₄ for Improved Photovoltaic Performance.

ABSTRACT: Cations and anions are replaced with Fe, Mn, and Se in CZTS in order to control the formations of the secondary phase, the band gap, and the micro structure of Cu₂ZnSnS₄. We demonstrate a simplified synthesis strategy for a range of quaternary chalcogenide nanoparticles such as Cu₂ZnSnS₄ (CZTS), Cu₂FeSnS₄ (CFTS), Cu₂MnSnS₄ (CMTS), Cu₂ZnSnSe₄ (CZTSe), and Cu₂ZnSn(S_0.5Se_0.5)₄ (CZTSSe) by thermolysis of metal chloride precursors using long chain amine molecules. It is observed that the crystal structure, band gap and micro structure of the CZTS thin films are affected by the substitution of anion/cations. Moreover, secondary phases are not o
