Small, Volume 21, Issue 19, May 12, 2025.A high‐efficiency Cd‐free CZTS solar cell of 11.9% efficiency is achieved by mitigating the charge‐compensation effect of Na interstitials in the CZTS absorber using device air annealing. The JSC and FF are significantly improved with enhanced electron mobility, hole density, and carrier collection efficiency in the depletion region.

Synthesis and characterization of CZTSe nanoinks using polyetheramine as solvent
Optical Materials Express, 2014 This study developed a novel one-step method for the synthesis of well-dispersed CZTSe nanoparticles from Cu, Zn, Sn, Se elemental powders using a solvent-thermal reflux technique. Polyetheramine was used as a solvent and chelating agent, which provided two NH2 bonding sites at the ends as well as long, continuous epoxy chains in the center, making it ...
