9.0% efficient Cu2ZnSn(S,Se)4 solar cells from selenized nanoparticle inks

Thin-film solar cells using Cu2ZnSn(S,Se)4 absorber materials continue to attract increasing attention. The synthesis of kesterite Cu2ZnSnS4 nanoparticles by a modified method of hot injection is explained. Characterization of the nanoparticles by …

Cu2ZnSn(S,Se)4 solar cells from inks of heterogeneous Cu–Zn–Sn–S nanocrystals

The solution-based synthesis of quaternary Cu2ZnSnS4 (CZTS) nanocrystals and further processing into a homogeneous photovoltaic absorber film prove challenging due to the stability of binary and ternary chalcogenide compounds comprised of Cu, Zn, and …
