Issue Date: | 2023 | Publisher: | SPRINGER HEIDELBERG | Source: | APPLIED PHYSICS A-MATERIALS SCIENCE & PROCESSING, 129 (6) (Art N° 404) | Abstract: | Kesterite Cu2ZnSnS4 (CZTS) has emerged as a potential alternative absorber for thin-film solar cells (TFSCs) and tandem applications owing to their earth-abundant, non-toxic materials and suitable direct bandgap (1.5 eV). This work reports the synthesis of CZTS molecular inks and subsequent deposition by ultrasonic spray coating. Clear and stable molecular inks of CZTS are synthesized with methanol as a solvent in a controlled environment. Characterization of the deposited material revealed smooth, homogeneous and compact films of pure single phase p-type kesterite, with an energy bandgap of 1.52 eV and activation energy of 44 meV. Fabrication of photovoltaic (PV) functional layers via ink-based deposition have the potential to bring down costs and allow sustainable growth of the technology. | Notes: | Ghediya, PR; Deferme, W (corresponding author), Hasselt Univ, Inst Mat Res IMO, Wetenschaps Pk 1, B-3590 Diepenbeek, Belgium.; Ghediya, PR; Deferme, W (corresponding author), Div IMOMEC, Imec Vzw, Wetenschaps Pk 1, B-3590 Diepenbeek, Belgium.; Ghediya, PR (corresponding author), EnergyVille, Thorpk 8320, B-3600 Genk, Belgium.; Ghediya, PR (corresponding author), Marwadi Univ, Dept Phys, Rajkot Morbi Highway, Rajkot 360003, Gujarat, India.; Ghediya, PR (corresponding author), Hokkaido Univ, Res Inst Elect Sci, N20W, Sapporo 100010020, Japan. prashantghediya@gmail.com; wim.deferme@uhasselt.be |
