Cation/Anion Substitution in Cu2ZnSnS4 for Improved Photovoltaic Performance
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 Cu 2 ZnSnS 4 . We demonstrate a simplified synthesis strategy for a range of quaternary chalcogenide nanoparticles such as Cu 2 ZnSnS 4 (CZT...
