Manufacturing method of AgBiS2 nanocrystal ink and colloid nanocrystal solar-cell manufactured using the same

摘要

The invention AgBiS ₂ relates to a production method and this the colloidal nanoparticles solar cell prepared using the nanoparticle ink, specifically AgBiS ₂ colloid comprising a first ligand disposed on AgBiS ₂ nanoparticle core and the core Preparing a first solution in which the nanoparticles are dispersed in an organic solvent; Preparing a second solution in which at least one metal halide and methyl ammonium halide of AgX (X: halogen element) and BiX _{3 are dissolved in a polar solvent;} And forming a AgBiS _second nanoparticle ink to mix and comprising a second ligand disposed on AgBiS ₂ nanoparticle core and the core of the first solution and the second solution; Preparation of AgBiS _second nanoparticle ink including It relates to a method and a colloidal nanoparticle solar cell manufactured using the same.
