“…Due to their unique optical properties, phototransistors based on the self-assembled films of the Ag-CdS icosapods were fabricated to explore their performance. It is well-known that the high morphological uniformity of a nanostructure is a prerequisite for exploration of its self-assembly behavior and that branched structures facilely tend to interlock together to form large-area superstructures. ,, For instance, highly monodisperse CdSe/CdS tetrapods and octapods can be flexibly self-assembled into linear chain structures and three-dimensional superstructures under optimal conditions, thus providing a good platform for subsequent understanding of their structure–property correlation. ,− …”

Plasmonic metal–semiconductor heterostructures with well-defined morphologies and spatial architectures have emerged as promising materials for wide applications in photocatalysis and optoelectronics. However, the synthesis of such structures with high quality and high yield remains a great challenge due to the incompatibility between the two materials. Herein, we report an optimized approach for the controlled preparation of branched Ag-CdS icosapods, which possess 20 CdS arms with an ordered spatial arrangement on the Ag cores. Moreover, the length, diameter, and thickness of the CdS arms on the Ag nanoparticles can be precisely tuned by the synthetic conditions, leading to Ag-CdS icosapods with tunable absorption properties. Furthermore, more complex hierarchical nanostructures can be achieved by the secondary growth of nanoplate arrays on the CdS arms. As a proof of concept, a phototransistor based on the self-assembled monolayer film of Ag-CdS icosapods shows a stable photoresponse and quite a fast switching performance under optical illumination of 540 nm without excitation of the CdS, which originates from the generation and transfer of plasmon-induced hot carriers in the Ag-CdS icosapods under an applied bias. This work offers a reproducible approach to finely tuning metal–semiconductor heterostructures with desirable architectures and paves the way for more deeply understanding their structure–property correlation.

“…In contrast, SrZrS 3 has two distorted structures, depending on the synthesis process, low‐temperature form NH 4 CdCl 3 , also known as (α‐phase), while high‐temperature form (β‐phase) GeFeO 3 ‐type with about 980–1000 °C phase transition occur. [ 65 ] Furthermore, Sun et al [ 14 ] have documented the bandgaps of 18 ABX 3 compounds, including promising candidates for IPVs, like CaZrS 3 , SrZrS 3 , BaZrS 3 , BaHfS 3 , CaHfSe 3 , and SrHfSe 3 (Figure 7d). Notably, the absorber layer for chalcogen perovskites can be thinner than that of emerging Pb‐based perovskites.…”

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.

“…Unlike their halide counterparts, they are chemically stable and typically do not contain potentially harmful Pb-Ions [1][2][3]. They also feature additionally interesting properties including good electronics transport properties, high absorption coefficient especially near the band edge and ferroelectric and ferromagnetic properties [4][5][6][7][8][9][10][11][12]. In order to better understand these properties and successfully implement these materials in applications, a variety of high-quality synthesis methods need to be available.…”

Current research efforts in the field of the semiconducting chalcogenide perovskites are directed towards the fabrication of thin films and subsequently determine their performance in the photovoltaic application. These efforts are motivated by the outstanding properties of this class of materials in terms of stability, high absorption coefficient near the band edge and no significant health concerns compared to their halide counterparts. The approach followed here is to use stacked precursor layers and is adopted from other chalcogenide photovoltaic materials like the kesterites and chalcopyrites. The successful synthesis of BaZrS3 from stacked layers of BaS and Zr and annealing at high temperatures (~1100 °C) with the addition of elemental sulfur is demonstrated. However, the film shows the presence of secondary phases and a flawed surface. As an alternative to this, BaS3 could be used as precursor due to its low melting point of 554 °C. Previously, the fabrication of BaS3 films was demonstrated, but in order to utilize them in the fabrication of BaZrS3 thin films, their microstructure and processing are further improved in this work by reducing the synthesis temperature to 300 °C, resulting in a smoother surface. This work lays the groundwork for future research in the fabrication of chalcogenide perovskites utilizing stacked layers and BaS3.
