“…In addition, the <400 °C fabrication temperature makes it possible for Sb 2 Se 3 to be deposited onto metal foil and even organic polymer substrates. [66] Recently, flexible Sb 2 Se 3 solar cells have been fabricated on Mo foils or polyimides, [66][67][68] and the devices presented superior bending stability and lightweight property. An impressive efficiency of 6.13% and powerper-weight of 2.04 W g À1 was fulfilled.…”

“…Theoretical calculation demonstrates that Sb 2 Se 3 has a high fracture strain of 28%, [ 65 ] so Sb 2 Se 3 has intrinsic advantages in flexible solar cells than other inorganic solar cells. [ 66 ] If the Sb 2 Se 3 film is well aligned to [001] orientation, there should in principle be no device performance degradation when bent to the extreme that the fracture occurs, thanks to the advantages of the benign grain boundaries. [ 6 ] Thus, Sb 2 Se 3 should enjoy intrinsically better flexibility compared to conventional thin film solar cells.…”

Antimony selenide (Sb2Se3) has emerged as a promising absorber material for photovoltaic application. Since the first pure‐phase Sb2Se3 solar cell reported ten years ago, increasing research has been carried out on this system with the device efficiency now reaching 9.2%. This work aims to present the major milestones of Sb2Se3 thin film solar cells from its birth to the present, including the selection of Sb2Se3 for thin film photovoltaics, the choice of planar device configuration instead of sensitized device, switching from solution processing to vacuum processing, new concept of orientation control and benign grain boundaries, discovery of unusual and complex defects, and post selenization for defect passivation. In the end, the authors discuss the competitive applications of Sb2Se3 solar cells in flexible devices and outlook their future development.

Antimony sulfide (Sb2S3) with a 1D molecular structure has strong bending characteristics, showing great application potential in flexible devices. Herein, the flexible substrate‐structured Sb2S3 solar cells is developed and improve device performances by the back interface selenization. The high‐quality Sb2S3 film with an optimal thickness of 1.8 µm, ensuring efficient spectra utilization, is deposited on flexible Mo foils by the rapid thermal evaporation technique. To solve the issues of back interfacial recombination and charge transport, the 20 nm MoSe2 layer between Sb2S3 film and Mo foil is fabricated by substrate selenization in the tube furnace. Further investigations indicate that the MoSe2 layer improves the interfacial energy band alignments and induces the [hk1] orientation of Sb2S3 film, thereby passivating defects and enhancing the carrier transport capacity. The flexible solar cell in the structure of Mo foil/MoSe2/Sb2S3/CdS/ITO/Ag, exhibiting good flexibility to stand thousands of bending, achieves an efficiency of 3.75%, which is the highest for Sb2S3 devices in substrate configuration. The presented flexible structure and back interfacial selenization study will provide new prospects for inorganic Sb2S3 thin film solar cells.

Photodetectors (PDs) rapidly capture optical signals and convert them into electrical signals, making them indispensable in a variety of applications including imaging, optical communication, remote sensing, and biological detection. Recently, antimony selenide (Sb2Se3) has achieved remarkable progress due to its earth‐abundant, low toxicity, low price, suitable bandgap width, high absorption coefficient, and unique structural characteristics. Sb2Se3 has been extensively studied in solar cells, but there's a lack of timely updates in the field of PDs. A literature review based on Sb2Se3 PDs is urgently warranted. This review aims to provide a concise understanding of the latest progress in Sb2Se3 PDs, with a focus on the basic characteristics and the performance optimization for Sb2Se3 photoconductive‐type and photodiode‐type detectors, including nanostructure regulation, process optimization, and stability improvement of flexible devices. Furthermore, the application progresses of Sb2Se3 PDs in heart rate monitoring, and monolithic‐integrated matrix images are introduced. Finally, this review presents various strategies with potential and feasibility to address challenges for the rapid development and commercial application of Sb2Se3 PDs.
