“…CZTS has a bandgap of around 1.5 eV, which means that it can absorb a significant portion of the solar spectrum. The absorption coefficient of CZTS is also high ( α = 10 4 cm −1 ), 40 which means that it can absorb light more efficiently than other semiconductor materials used in scs. The recombination profile in CZTS scs is affected by several types of defects, including point defects, grain boundaries, and anti‐site defects.…”

The present paper deals with the photovoltaic performance‐based numerical evaluation of copper–zinc–tin–sulfur (CZTS) solar cells embedded with CZTSe as a back surface field (BSF) layer. CZTS has been considered a leading candidate for the fabrication of solar devices owing to its availability and absence of toxicity. Adding a BSF layer to a solar device is a novel way to boost efficiency. It reduces the recombination of the carriers at the back surface, thus increasing the overall current output of the solar cells. SCAPS 1D simulator is used to study the impact of several parameters on electrical properties like temperature, the thickness of the CZTS layer, acceptor doping concentration, and the impact of series and shunt resistances. Considering the optimized parameters in each layer of the solar cells, this work delivers 24.7% efficiency with the BSF layer, which is 8% more than that without the BSF layer. The results of this modeling will facilitate researchers to fabricate a highly efficient CZTS solar cell.

“…and FF [35]. Owing to the high-absorption coefficient of CZTS [15], a few hundred nanometer film is capable of absorbing enough sunlight. Therefore, the increment in sc J , FF and η is found more significant at the thickness increment in the lower range from 100 nm to 900 nm of the absorber layer.…”

This study explored the performances of CZTS-based thin-film solar cell with three novel buffer layer materials ZnS, CdS, and CdZnS, as well as with variation in thickness of buffer and absorber-layer, doping concentrations of absorber-layer material and operating temperature. Our aims focused to identify the most optimal thin-film solar cell structure that offers high efficiency and lower toxicity which are desirable for sustainable and eco-friendly energy sources globally. SCAPS-1D, widely used software for modeling and simulating solar cells, has been used and solar cell fundamental performance parameters such as open-circuited voltage ( oc V ), short-circuited current density ( sc J ), fill-factor( FF ) and efficiency(η ) have been optimized in this study.

“…e use of nanotechnology has increased efficiency while reducing the cost of solar cells [4]. In addition, CZTS has a bandgap between 1.45 and 1.65 eV along with a high absorption coefficient of more than 10 4 cm −1 and a refractive index of 2.72 [5][6][7][8][9]. It can be obtained by cospraying copper (Cu), tin (II), sulfide (SnS), and zinc sulfide (ZnS) for the deposition of precursors and followed by sulfurization in a hydrogen sulfide (H 2 S) atmosphere [9], or by spraying metal precursors Copper-zinc-tin (Cu-Zn-Sn) from a single target, followed by vaporization of sulfur [10].…”

Copper-zinc-tin-sulfide (CZTS) solar cells have now become a topic of interest in the solar power generation industry. These are used as an absorber in the zinc oxide (ZnO)/cadmium sulfide (CdS) core-shell nanowire arrays, in order to improve the performance of solar cells. The relationship between the average increase in absorption rates and CdS shell thickness (compared to the thin film) reveals that the optimum thickness with the maximum average absorption rate (39.95%) compared to thin film is 30 nm. The cells’ electrical and optical performance was significantly improved with the introduction of graphene between the ZnO and CdS layers. The shell thicknesses for a better performance of these nanowire solar cells were 30 and 40 nm, with almost the same open-circuit voltage, the similar short-circuit current density, and efficiency, which were 630 mV, 6.39 mA/cm2, and 16.8%, respectively. Furthermore, a minimum reflection of 40% was obtained with these same shell thicknesses.
