“…[ 39–41 ] There are different approaches for fabricating crystalline Cs 2 SnI 6 thin films. [ 41–49 ] In a facile and popular solution‐based route, [ 50–55 ] concentrated acidic solution of cesium iodide (CsI) is first made by mixing aqueous hydrogen iodide (HI) and cesium carbonate (Cs 2 CO 3 ). Subsequently, black truncated octahedral Cs 2 SnI 6 crystals are obtained by adding alcoholic Tin (IV) iodide (SnI 4 ) to the aqueous CsI solution.…”

A novel low‐temperature route is developed for inkjet printing of the perovskite Cs2SnI6, to create wearable negative‐temperature‐coefficient thermistors with unprecedented performance on thermally sensitive fabrics. A low processing temperature of 120 °C is achieved by creating a stable and printable ink using binary metal iodide salts, which is thermally transformed into dense Cs2SnI6 crystals after printing. The optimally printed Cs2SnI6 shows a temperature measurement range up to 120 °C, high sensitivity (4400 K), and temperature coefficient of resistivity (0.05 °C−1), and stability under ambient environmental conditions and bending. The approach breaks a critical tradeoff that has hindered wearable fabric‐based thermistors by enabling damage‐free fabrication of devices with commercially comparable performance, evincing significant applications in multifunctional textiles and beyond.

“…For the first time, solution‐processed Cs 2 SnI 6 films were investigated for potential application in photoelectrochemical water splitting. [ 148 ] The fabricated device based on Cs 2 SnI 6 electrode, yielded a PCE of 0.54% at 0.8 V and a photocurrent density of 0.92 mA cm −2 , which implies the p‐type nature of Cs 2 SnI 6 (Figure 12e). Recently, a novel low‐temperature route was developed for the direct fabrication of high‐performance Cs 2 SnI 6 ‐based wearable negative‐temperature‐coefficient (NTC) thermistors on thermally sensitive fabrics.…”

Since the booming research on perovskite solar cells (PSCs), organic–inorganic hybrid halide perovskites have triggered widespread research attention. This is seen in the unprecedented improvement of the power conversion efficiency (PCE) from an initial 3.8% to a remarkable 25.5%. Despite the fascinating improvement in PCEs, the toxicity of the detrimental lead element is a major limiting factor that hampers the commercialization prospect of lead‐based materials. Extensive efforts have been dedicated to the progress of lead‐free, stable, and ecofriendly perovskite materials for green‐energy applications. Recently, double‐halide Cs2SnI6 perovskite emerged as a star material due to its favorable optoelectronic properties, stable nature, and environmental friendliness. Thus, an in‐time review to recapitulate the recent advances of Cs2SnI6 is critical to provide viable theoretical and experimental strategies for synergic optimization of perovskite films. Herein, the theoretical and experimental understandings of the properties of Cs2SnI6 are summarized and the different fabrication methodologies and their influences on the properties of Cs2SnI6 are discussed. The application potential of Cs2SnI6 is further reviewed and the limiting factors that influence the performance of Cs2SnI6 devices are highlighted. In the end, prospective research directions to improve the optoelectronic properties are presented for developing efficient Cs2SnI6 devices.

In the development of hydrogen-based technology, a key challenge is the sustainable production of hydrogen in terms of energy consumption and environmental aspects. However, existing methods mainly rely on fossil fuels due to their cost efficiency, and as such, it is difficult to be completely independent of carbon-based technology. Electrochemical hydrogen production is essential, since it has shown the successful generation of hydrogen gas of high purity. Similarly, the photoelectrochemical (PEC) method is also appealing, as this method exhibits highly active and stable water splitting with the help of solar energy. In this article, we review recent developments in PEC water splitting, particularly those using metal-organic halide perovskite materials. We discuss the exceptional optical and electrical characteristics which often dictate PEC performance. We further extend our discussion to the material limit of perovskite under a hydrogen production environment, i.e., that PEC reactions often degrade the contact between the electrode and the electrolyte. Finally, we introduce recent improvements in the stability of a perovskite-based PEC device.
