Highly efficient copper-zinc-tin-selenide (Cu2ZnSnSe4 ; CZTSe) thin-film solar cells are prepared via the electrodepostion technique. A metallic alloy precursor (CZT) film with a Cu-poor, Zn-rich composition is directly deposited from a single aqueous bath under a constant current, and the precursor film is converted to CZTSe by annealing under a Se atmosphere at temperatures ranging from 400 °C to 600 °C. The crystallization of CZTSe starts at 400 °C and is completed at 500 °C, while crystal growth continues at higher temperatures. Owing to compromises between enhanced crystallinity and poor physical properties, CZTSe thin films annealed at 550 °C exhibit the best and most-stable device performances, reaching up to 8.0 % active efficiency; among the highest efficiencies for CZTSe thin-film solar cells prepared by electrodeposition. Further analysis of the electronic properties and a comparison with another state-of-the-art device prepared from a hydrazine-based solution, suggests that the conversion efficiency can be further improved by optimizing parameters such as film thickness, antireflection coating, MoSe2 formation, and p-n junction properties.

“…[1] A variety of synthetic processes, including thermal co-evaporation, [2] sputtering, [3] pulsed laser deposition, [4] solution processes, [5] and electrochemical deposition, [6,7] have been applied in the preparation of CZTSSe thin films. This is mainly due to the high energy production costs.…”

The metallic precursor films were annealed in a quartz tube furnace under a sulfur atmosphere (vaporized elemental sulfur with high-purity Ar carrier gas) [18], and the films were sulfurized at various temperatures at around 550°C. KCN etching was performed with a 10% KCN solution with distilled water for 3 min.…”

“…CZTS absorber layer have been deposited by using various processes [4][5][6][7][8][9][10]. Recently, electrodeposition was proposed and studied for a large-area and low-cost film deposition method [11][12][13][14][15]. In this method, CZTS absorber layer is grown by sulfurizing after preheating the electrodeposited Cu/Sn/Zn metallic precursor layer.…”

Cu2ZnSnS4 (CZTS) is paid attention to the low‐cost and nontoxic solar cell material. In this study, CZTS thin film was deposited by using an electrodeposition technique followed by a sulfurization after preheating the deposited metallic precursor layer. We investigated the film properties of CZTS thin films for understanding the effect of preheating time on the photovoltaic properties such as carrier lifetime and recombination mechanism by using a microwave photoconductivity decay (μ‐PCD) and a photoluminescence (PL) measurement. The results of the μ‐PCD measurements showed that carrier lifetime increased with increasing the preheating time and longer carrier lifetime was observed in a part of deposited thin film. The PL measurements showed the peak energy shift to lower energy region by a surface position of the sample preheated for 150 min. We found the CZTS crystal quality improved but the homogeneity worsened with increasing the preheating time. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
