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 …
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 …
The ability to alloy Cu2ZnSn(S,Se)4 with Ge provides a unique ability to band-gap engineer the absorber film by controlling the relative cation ratios. In here, a preliminary study on adjusting the Ge to Sn ratio is shown to significantly improve the …
