“…The numbers of publications and citations substantially increased each year, especially in the most recent decade, suggesting an obvious trend for antimony chalcogenide solar cell research. Although antimony chalcogenides have shown good properties, and numerous achievements have been made in photovoltaic fields using these materials, a limited number of articles can be found featuring the improvements, problems, and directions of the efforts in antimony chalcogenide‐based solar cell applications . The published review papers all present certain important aspects of antimony chalcogenide solar cells well, however, these papers clearly do not cover all aspects of Sb 2 S 3 solar cells, Sb 2 Se 3 solar cells, and Sb 2 (S x Se 1−x ) 3 solar cells.…”

Antimony chalcogenides such as Sb2S3, Sb2Se3, and Sb2(SxSe1−x)3 have emerged as very promising alternative solar absorber materials due to their high stability, abundant elemental storage, nontoxicity, low‐cost, suitable tunable bandgap, and high absorption coefficient. Remarkable achievements have been made in antimony chalcogenide solar cells in the past few decades, with the power conversion efficiency (PCE) currently reaching 9.2%, which is close to the PCE level required for industrial applications. To facilitate the realization of highly efficient antimony chalcogenide solar cells in the future, a comprehensive review of antimony chalcogenide‐based materials and photovoltaic devices is presented. First, the fundamental physical properties and preparation methods of antimony chalcogenide‐based materials are outlined, and then, notable recent developments in antimony chalcogenide‐based photovoltaic devices with various architectures are highlighted. Finally, the most prominent limitations are described, and approaches to achieving remarkable advances in antimony chalcogenide solar cells in the future are provided.

“…Among them, antimony sulfide (Sb 2 S 3 ) is a binary semiconductor compound with a single stable phase, which could avoid the formation of other secondary phases . In particular, Sb 2 S 3 received considerable attention for light absorber material in solar cells due to its suitable bandgap of 1.7–1.8 eV with high absorption coefficient of 10 5 cm −1 in the visible range, abundant and environmental friendly compositional elements, and excellent air stability . This bandgap allows its application as absorber in single‐junction solar cell or in top cell of the multijunction tandem photovoltaic device.…”

Sb 2 S 3 has attracted great research interest very recently as a promising absorber material for photoelectric and photovoltaic devices because of its unique optical and electrical properties and single, stable phase. However, the intrinsic high resistivity property of Sb 2 S 3 material is one of the major factors restricting the further improvement of its application. In this work, the C 60 modification of Sb 2 S 3 thin films is investigated. The conductivity of Sb 2 S 3 thin films increases from 4.71 × 10 −9 S cm −1 for unmodified condition to 2.86 × 10 −8 S cm −1 for modified thin films. Thin‐film solar cells in the configuration of glass/(SnO 2 :F) FTO/TiO 2 /Sb 2 S 3 (C 60 )/Spiro‐OMeTAD/Au are fabricated, and the conversion efficiency is increased from 1.10% to 1.74%.

“…To probe the influence of alkali‐metal doping on the charge carrier concentration of doped Sb 2 S 3 , we then carried out Mott‐Schottky analysis by measuring the capacitance–voltage ( C – V ) characteristic curves of the complete devices under dark at room temperature condition based on Equation :

\frac{1}{C^{2}} = \frac{2}{ϵ_{0} ϵ e A^{2} N} (V_{b i} - V)

where C is capacitance, A is device area, ϵ 0 is the vacuum dielectric constant, ϵ is the relative dielectric constant of the Sb 2 S 3 films with a value of 5 from literature, e is elementary charge, N is carrier concentration and V bi is the built‐in potential, respectively. The carrier concentration N is inversely proportional to the slope of Mott–Schottky plot (1/ C 2 is plotted against the applied voltage V ) and the V bi is estimated by the X‐intercept.…”

Alkali Metals Doping for High‐Performance Planar Heterojunction Sb₂S₃ Solar Cells

et al. 2018

Sb2S3 as a stable light harvesting material has received increasing attention for solar cell applications. To improve the device efficiency, much effort has been put into the materials synthesis, interfacial engineering, and device structure design. Here, it is demonstrated that doping of alkali metal (Li, Na, K, Rb, Cs) ions essentially affects the morphological, crystal, optical and electrical properties of Sb2S3 films. The structural and compositional analysis shows that the doping is in form of alkali metal‐sulfur chemical bond at both surface and grain boundaries of Sb2S3 films. Compared with the pristine Sb2S3, we observe that Li and Na doping are not able to improve the device efficiency, while K, Rb, and Cs notably increase energy conversion efficiency. The most effective enhancement is found in Cs‐doped Sb2S3, where the carrier concentration, crystallinity, and film formability show remarkable improvement. The device based on the Cs‐Sb2S3 film delivers a power conversion efficiency of 6.56%, which is the highest efficiency in planar heterojunction Sb2S3 solar cells, regardless of whether the films are fabricated by a solution process or thermal deposition. This research identifies that doping of heavy alkali metals is an effective approach to improve the performance of Sb2S3 solar cells.
