Cu₂ZnSnSe₄Thin Films Preparation by Pulsed Laser Deposition Using Powder Compacted Target

Abstract

Cu 2 ZnSnSe 4 thin films for solar absorber application were prepared by pulsed laser deposition of a synthesized Cu 2 ZnSnSe 4 compound target. The film's composition revealed that the deposited films possess an identical composition with the target material. Further film compositional control toward a stoichiometric composition was performed by optimizing substrate temperature, deposition time and target rotational speed. At the optimum condition, X-ray diffraction patterns of films showed that the films demonstrated polycrystalline stannite single phase with a high degree of (112) .
