“…As stated in Section , the BaZrS 3 absorber showed its best performance at an optimum thickness of 1000 nm. This can be achieved using various techniques such as vapor deposition, sputtering, and electrodeposition, which allow for better control over factors like film thickness, composition, purity, and uniformity by changing deposition conditions such as time, temperature, pressure, and potential . The film thickness can be increased by repeating the deposition time and annealing steps.…”

Furthermore, Meng et al reported that BaZrS 3 and Ba(Zr,Ti)S 3 films synthesized under S-rich/Zr-poor conditions exhibit strong p-type behavior with an optimum carrier concentration of 10 15 cm –3 and surpass the deep-level defects due to their high formation energy that results in lower defect density.…”

BaZrS3 chalcogenide perovskites have emerged as a promising absorber due to their exceptional properties. However, there are no experimental reports on the applicability of BaZrS3 in photovoltaics. Thus, theoretical knowledge of device structure engineering is essential for its successful fabrication. In this regard, we have proposed various BaZrS3 device configurations by altering 12 electron transport layers (ETLs) in combination with 13 hole transport layers (HTLs) using SCAPS-1D, wherein a total of 782 devices are simulated by tuning the thickness, carrier concentration, and defect density of BaZrS3, ETLs, and HTLs. Interestingly, the absorber’s thickness optimization enhanced the absorption in the device by 2.31 times, elevating the generation rate of charge carriers, while the increase in its carrier concentration boosted the built-in potential from 0.8 to 1.68 V, reducing the accumulation of charge carriers at the interfaces. Notably, on further optimization of ETL and HTL combinations, the best power conversion efficiency (PCE) of 28.08% is achieved for FTO/ZrS2/BaZrS3/SnS/Au, occurring due to the suppressed barrier height of 0.1 eV at the ZrS2/BaZrS3 interface and degenerate behavior of SnS, which increased charge carrier transportation and conductivity of the devices. Upon optimizing the work function, an ohmic contact is achieved for Pt, boosting the PCE to 28.17%. Finally, the impact of Ti alloying on BaZrS3 properties is examined on the champion FTO/ZrS2/BaZrS3/SnS/Pt device where the maximum PCE of 32.58% is obtained for Ba(Zr0.96,Ti0.04)S3 at a thickness of 700 nm due to extended absorption in the NIR region. Thus, this work opens doors to researchers for the experimental realization of high PCE in BaZrS3 devices.

Ba(Zr,Hf)S3 solid solutions are proposed for photovoltaic applications and a fast non‐destructive measurement of the composition of these solutions and the identification of any possible secondary phases is a prerequisite for understanding their opto‐electronic properties. Here we calculate the non‐resonant one‐phonon Raman spectra of pure BaHfS3 and BaZrS3, which show only subtle differences between them. To test this experimentally, a solution series of BaZr1‐xHfxS3 (0≤x≤1) powders was synthesised and free of a secondary phase, HfS3 identified by 633 nm excitation Raman spectroscopy. The veracity of the synthesis method was confirmed by comparing X‐ray diffractograms and optical absorption spectra of the BaZr0.5Hf0.5S3 solid solution to a 50:50 mixture of the pure ternary compounds. Experimental non‐resonant Raman measurements on the solid solution powders confirm that only slight variations in the spectra are visible, making a solid solution composition determination difficult. However, exciting the solid solutions resonantly, leads to the appearance of new two‐phonon modes in the Raman spectrum, which change significantly across the solid solution series. We consequently suggest that a rapid solid solution composition measurement can be made unambiguously by measuring the ratio of the intensities of the 825 cm‐1 and 625 cm‐1 Raman features.

Empowering Indoor Photovoltaics: Stable Lead‐Free Perovskites and Beyond

Indoor photovoltaics (IPVs) have garnered significant attention in recent years due to their potential to empower small portable electronic devices and the Internet of Things (IoT). After silicon solar cells, it is now widely acknowledged that the dominant technology in the field of outdoor/indoor photovoltaics is hybrid lead (Pb) halide perovskites. Despite the fascinating characteristics of hybrid Pb‐halide perovskites, the presence of toxic Pb is regarded as one of the major factors that prevent commercialization. Low‐toxic, Pb‐free, and stable perovskites are also being used in outdoor solar cells (ODSCs), but their efficiencies are low due to large bandgap (i.e. ∽2.0 eV). Recently, some of the stable, Pb‐free perovskite materials have drawn great interest due to their initial performance across various fields, including light‐emitting diodes (LEDs), photodetectors, X‐rays, photocatalysis, ODSCs, and in IPVs. In this perspective, we summarized the current status and prospects for Pb‐free halide perovskites, chalcogen perovskites, silver bismuth halide (AaBbXa+3b) family, and other chalcogen materials are being explored to speed up the progress of IPVs.This article is protected by copyright.
