Methods for preparing Cu2ZnSnS4 nanoparticles for use in thin film photovoltaic cells

摘要

Materials and methods for preparing Cu₂ZnSnS₄ (CZTS) layers for use in thin film photovoltaic (PV) cells are disclosed herein. The CZTS materials are nanoparticles prepared by a colloidal synthesis in the presence of a labile organothiol. The organothiol serves as both a sulphur source and as a capping ligand for the nanoparticles.
