Title: Post‐Annealing Treatment on Hydrothermally Grown Antimony Sulfoselenide Thin Films for Efficient Solar Cells
Herein, antimony sulfoselenide (Sb2(S, Se)3) thin‐film solar cells are fabricated by a hydrothermal method followed by a post‐deposition annealing process at different temperatures and the impact of the annealing temperature on the morphological, structural, optoelectronic, and defect properties of the hydrothermally grown Sb2(S, Se)3films is investigated. It is found that a proper annealing temperature leads to high‐quality Sb2(S, Se)3films with large crystal grains, high crystallinity, preferred crystal orientation, smooth and uniform morphology, and reduced defect density. These results show that suppressing deep‐level defects is crucial to enhance solar cell performance. After optimizing the annealing process, Sb2(S, Se)3solar cells with an improved power conversion efficiency 2.04 to 8.48% are obtained.  more » « less

    Antimony selenide (Sb2Se3) emerges as a promising sunlight absorber in thin film photovoltaic applications due to its excellent light absorption properties and carrier transport behavior, attributed to the quasi‐one‐dimensional Sb4Se6‐nanoribbon crystal structure. Overcoming the challenge of aligning Sb2Se3‐nanoribbons normal to substrates for efficient photogenerated carrier extraction, a solution‐processed nanocrystalline Sb2(S,Se)3‐seeds are employed on the CdS buffer layer. These seeds facilitate superstrated Sb2Se3thin film solar cell growth through a close‐space sublimation approach. The Sb2(S,Se)3‐seeds guided the Sb2Se3absorber growth along a [002]‐preferred crystal orientation, ensuring a smoother interface with the CdS window layer. Remarkably, Sb2(S,Se)3‐seeds improve carrier transport, reduce series resistance, and increase charge recombination resistance, resulting in an enhanced power conversion efficiency of 7.52%. This cost‐effective solution‐processed seeds planting approach holds promise for advancing chalcogenide‐based thin film solar cells in large‐scale manufacturing.

    Antimony chalcogenides (Sb2X3, where X = S, Se, or SxSe1−x) are promising materials for thin‐film solar cells due to their tunable bandgaps (1.1–1.8 eV), high absorption coefficients (>105cm−1), nontoxicity, and earth‐abundant composition. Recent advancements have achieved power conversion efficiencies (PCEs) exceeding 10%, with a record of 10.81% for Sb2(S, Se)3cells. However, interface‐related issues, such as recombination losses and open‐circuit voltage (VOC) deficits, limit performance. Interface engineering strategies have significantly improved device efficiency and stability, including buffer layer optimization, defect passivation, surface treatments, post‐processing, and doping. This review summarizes the latest developments in these areas, discusses ongoing challenges, and proposes future research directions to enhance the performance of antimony chalcogenide solar cells.

    Abstract The synthesis of BaZr(S,Se)3chalcogenide perovskite alloys is demonstrated by selenization of BaZrS3thin films. The anion‐exchange process produces films with tunable composition and band gap without changing the orthorhombic perovskite crystal structure or the film microstructure. The direct band gap is tunable between 1.5 and 1.9 eV. The alloy films made in this way feature one‐hundred‐times stronger photoconductive response and a lower density of extended defects, compared to alloy films made by direct growth. The perovskite structure is stable in high‐selenium‐content thin films with and without epitaxy. The manufacturing‐compatible process of selenization in H2Se gas may spur the development of chalcogenide perovskite solar cell technology.

    ABSTRACT While silver selenide (Ag2Se) is considered a promisingn‐type thermoelectric material, the low throughput of conventional solid‐state processing for selenide‐based systems highlights the need for scalable solution‐based alternatives. However, most solution‐processing approaches require thermal annealing to form high‐quality films, whereas Ag2Se exhibits limited thermal stability (<350°C), posing a nontrivial issue for processing. To address this, we systematically investigate the incorporation of a controlled dual dopant (Sb‐Se) into Ag2Se through a compositionally tuned nano‐ink. Flexible SbxAgSe0.5+yfilms were fabricated using the direct ink writing (DIW) approach, and the doped films demonstrated enhanced thermal stability. The effect of dopants on microstructure was further studied using neutron diffraction at the VULCAN instrument and elemental analysis using SEM‐EDS. Results demonstrated that elemental doping of Sb and Se leads to stable/enhanced Seebeck coefficients after thermal exposure, in contrast to undoped Ag2Se films with decreased Seebeck due to thermal degradation, where the thermal behavior and possible degradation pathways are evaluated at 200, 400, and 600°C. A wearable thermoelectric generator (TEG) demonstrated a peak power density of ∼60 µW cm−2at 30°C temperature difference. Overall, this study suggests the possibility of printing‐based Ag2Se thermoelectric devices with high‐temperature processability for waste‐heat harvesting and harsh electronic applications.

    While there has been rapid progress in the performance of perovskite solar cells, the details of film formation, effect of processing parameters and perovskite crystal structure are still under discussion. The details of the X-ray diffraction (XRD) pattern of the tetragonal phase of CH 3 NH 3 PbI 3 perovskite existing at room temperature are often overlooked, with unresolved (002) (at 2 θ = 13.99° for CuK α and q = 0.9927 Å −1 ) and (110) (at 2 θ = 14.14° and q = 1.003 Å −1 ) peaks considered to be one peak at 14°, leading to an inaccurate estimation of lattice parameters. In this study, we use an electrospray deposition technique to prepare perovskite films at room temperature, oriented in (002) and (110) directions, with (002) as the preferred orientation. The results of a detailed study on the emergence of the two orientations during perovskite formation are reported. The effect of process parameters, such as substrate temperature during deposition and annealing temperature, on the grain orientation was established using XRD and grazing incidence wide angle X-ray scattering (GIWAXS). The study suggests that an irreversible crystal reorientation from (002) to (110) occurs at high temperature during rapid annealing, whereas a reversible crystal thermal expansion is seen during slow annealing. Finally, the results of the grain reorientation are correlated with the film properties, and it is shown that the film with the dominant (110) orientation has improved morphology and optoelectronic properties. The detailed structural investigation and characterization presented in this study are important for the precise determination of crystal orientation and achievement of desirable photovoltaic properties of the absorber material by carefully observing the adjacent crystal plane peaks in the XRD pattern of the perovskite thin films.
