As a promising solar absorber material, antimony selenide (Sb2Se3) has gained popularity. However, a lack of knowledge regarding material and device physics has slowed the rapid growth of Sb2Se3-based devices. This study compares the experimental and computational analysis of the photovoltaic performance of Sb2Se3-/CdS-based solar cells. We construct a specific device that may be produced in any lab using the thermal evaporation technique. Experimentally, efficiency is improved from 0.96% to 1.36% by varying the absorber’s thickness. Experimental information on Sb2Se3, such as the band gap and thickness, is used in the simulation to check the performance of the device after the optimization of various other parameters, including the series and shunt resistance, and a theoretical maximum efficiency of 4.42% is achieved. Further, the device’s efficiency is improved to 11.27% by optimizing the various parameters of the active layer. It thus is demonstrated that the band gap and thickness of active layers strongly affect the overall performance of a photovoltaic device.

“…The method offers the advantage of high deposition rates, and it is widely used to deposit semiconductor materials such as CdTe [22]. More recently, this method was also used to fabricate Sb 2 Se 3 -based solar cells [23,24]. Thanks to the low melting point of Sb 2 Se 3 (608 • C) and the high saturated vapor pressure (around 100 Pa at 550 • C), CSS is a low-energy-consumption technique for Sb 2 Se 3 growth, and it is more likely to form (hk )-oriented grains with = 0, especially at certain substrate temperatures.…”

Sb2Se3, as an earth-abundant and low-toxic material, has emerged as one of the most interesting absorbers for clean renewable power generation technologies. Due to its optical properties, especially bandgap and absorption coefficient, the number of papers on Sb2Se3-based solar cells has been constantly increasing in the last ten years, and its power conversion efficiency has raised from 1% in 2014 to 10.57% in 2022. In this review, different Sb2Se3 solar cells’ fabrication technologies based on physical vapor deposition are described and correlated to the texture coefficient (ribbon orientation). Moreover, recent research works of the most promising solar cell configurations with different electron-transporting layers and hole-transporting layers are analyzed with a special emphasis on photovoltaic performances. Furthermore, different Sb2Se3 doping techniques are discussed. All these aspects are considered as new strategies to overcome the Sb2Se3 solar cell’s actual limitations.

“…In recent years, there has been a surge of research on the thin film deposition of antimony selenide (Sb 2 Se 3 ). A number of thin film deposition techniques have been used to fabricate Sb 2 Se 3 films, including spin-coating solutions on mesoporous oxides [12], thermal evaporation [10,13,14], sputtering [15][16][17], co-evaporation of Sb 2 Se 3 and Se [18], closespaced sublimation (CSS) [19][20][21], and injection vapor deposition (IVD) [22]. Recently, these two latter techniques demonstrated conversion efficiencies of 9.2% and 10.12%, respectively, while the record efficiency of 10.57% was obtained via additive-assisted chemical bath deposition (CBD).…”

In recent years, research attention has increasingly focused on thin-film photovoltaics utilizing Sb2Se3 as an ideal absorber layer. This compound is favored due to its abundance, non-toxic nature, long-term stability, and the potential to employ various cost-effective and scalable vapor deposition (PVD) routes. On the other hand, improving passivation, surface treatment and p-type carrier concentration is essential for developing high-performance and commercially viable Sb2Se3 solar cells. In this study, Cu-doped Sb2Se3 solar devices were fabricated using two distinct PVD techniques, pulsed electron deposition (PED) and radio frequency magnetron sputtering (RFMS). Furthermore, 5%Cu:Sb2Se3 films grown via PED exhibited high open-circuit voltages (VOC) of around 400 mV but very low short-circuit current densities (JSC). Conversely, RFMS-grown Sb2Se3 films resulted in low VOC values of around 300 mV and higher JSC. To enhance the photocurrent, we employed strategies involving a thin NaF layer to introduce controlled local doping at the back interface and a bilayer p-doped region grown sequentially using PED and RFMS. The optimized Sb2Se3 bilayer solar cell achieved a maximum efficiency of 5.25%.
