Low cost nanostructure kesterite CZTS thin films for solar cells application
Source abstract
Abstract
Abstract Nanostructure Cu2ZnSnS4 (CZTS) thin films were synthesized by Successive Ionic Layer Adsorption and Reaction (SILAR) method. The as-grown CZTS thin films have shown amorphous structure but after sulfurization at 450 °C temperature, CZTS thin films showed kesterite crystalline structure. The crystallite size of annealed CZTS thin films is to be ∼18 nm and kesterite structure was confirmed by XRD pattern and Raman spectra show pure CZTS peaks at 337 cm−1 and 368 cm−1. The FE-SEM images indicate the presence of small agglomerated grains & visible white pores of as grown and annealed samples. The direct band gap energy of CZTS thin films was decreased after annealing under sulfur atmosphere. CZTS thin films have suitable absorber material for solar cells confirmed by structural, optical and morphological properties. CdS quantum dot has been used as a window layer to deposit on Indium doped tin oxide (ITO) & Fluorine doped tin oxide (FTO) substrates for measured power conversion efficiency of CZTS material confirmed by J-V characteristics.
