Aqueous-based Binary Sulfide Nanoparticle Inks for Cu2ZnSnS4 Thin Films Stabilized with Tin(IV) Chalcogenide Complexes.

ABSTRACT: Cu2ZnSnS4(CZTS) is a promising semiconductor material for photovoltaic applications,with excellent optical and electronic properties while boasting a nontoxic, inexpensive, andabundant elemental composition. Previous high-quality CZTS thin films often required eithervacuum-based deposition processes or the use of organic ligands/solvents for ink formulation,which are associated with various issues regarding performance or economic feasibility. To addressthese issues, an alternative method for depositing CZTS thin films using an aqueous-basednanoparticle suspension is demonstrated in this work. Nanoparticles of constituent binary sulfides(CuxS and ZnS) are stabilized in an ink using tin(IV)-based, metal chalcogenide complexes such as[Sn2S6]4-. This research paper provides a systematic study
