Description
Solar cells based on kesterite-type Cu2ZnSnS4 have been successfully fabricated on ITO substrates by cost effective chemical bath deposition method. The structural properties of the material have been studied using X-ray diffraction pattern and it confirms the formation of Cu2ZnSnS4 with kesterite structure. The surface topography has been studied using atomic force microscope and the rms roughness of the film was found to be 3.2 nm. The chemical constituents present in the prepared films have been identified using energy dispersive X-ray analysis. The optical band gap energy of CZTS thin film was found to be 1.5 eV which is quite close to the optimum value required for solar cell application. The power conversion efficiency of fabricated Cu2ZnSnS4 based solar cell is 1.34%. (author)
