Tailoring the structural, optical, and optoelectrical properties of innovative n-type Ag2ZnSnS4 thin films and investigating ITO/Ag2ZnSnS4/SnS/Au heterojunction
This work aims to create silver zinc tin sulfide (Ag 2 ZnSnS 4 ) layers with various thicknesses (254, 381, 473, and 539 nm) by a simple chemical deposition technique. The X-ray diffraction data revealed that the as-prepared Ag 2 ZnSnS 4 films are polycrystalline, and all films have a single Ag 2 Zn...
