“…For the ILS-Ox4 series, increasing the amount of the functional groups in the sorbent structure decreased the sorption to 11%, which made it possible to use much milder desorption conditions than in the case of other materials. The XPS analysis of the functionalized silicas before and after the adsorption also confirmed the interaction of the functional group with the metals' cations [44][45][46]. For the series ILS-K3 and ILS-K4, before adsorption the high-resolution C 1s spectra were deconstructed into peaks at 284.8, 286.4, and 289.8, which were assigned to C=C, C=O, and C-O, respectively.…”

Removal of toxic contaminants such as Pb(II) from waste solutions is environmentally requested. Therefore, in this paper, for potential novel sorbents, mesoporous ionic liquid-functionalized silicas were synthesized and tested for the removal of Pb(II) from aqueous solutions. The successful synthesis of the adsorbents was proved by nuclear magnetic resonance (29Si and 13C NMR), Fourier transform infrared spectroscopy (FTIR), and elemental analysis. The structural and textural properties were determined using scanning electron microscopy (SEM), X-ray diffraction (XRD), high-resolution transmission electron microscopy (TEM), and low-temperature N2 sorption, and the result showed that the applied procedure made it possible to obtain highly ordered particles with a two-dimensional mesostructure. The effects of several parameters including initial pH, contact time, adsorption temperature, and Pb(II) concentration were studied in detail and were discussed to evaluate the adsorption properties of the fabricated materials towards Pb(II). The obtained results confirmed a very high potential of the sorbents; however, the adsorption properties depend on the structure and amounts of the functional group onto fabricated materials. The sample ILS-Ox3-40 showed fast kinetics (equilibrium reached within 10 min) and capacity of 172 mg/g, and that makes it a promising sorbent for the cleanup of water contaminated by lead. It was also indicated that, regardless on structure of the tested materials, the Pb(II) removal was spontaneous and exothermic. The fabricated mesoporous silicas exhibited that they were easy to regenerate and had excellent reusability.

“…Similarly, 3D/1D bilayer perovskite can also be prepared by in-situ growth method. For instance, Kaneko et al spin-coated 4-tert-butylpyridinium iodide on a 3D perovskite film, forming 1D perovskite TBPPbI 3 on the top [89]. Since the carrier mobility and binding energy of low-dimensional perovskite are relatively lower, therefore the morphology, such as the crystallinity, thickness, phase, film coverage of the low-dimensional perovskite are critical important for the device performance [90].…”

To reach the target of carbon neutral, a transition from fossil energy to renewable energy is indispensable. Photovoltaic technology is considered one of the most prominent sources of renewable energy. Recently, metal halide perovskite materials have attracted tremendous interest in the areas of optoelectronic devices due to their ease of processing and outstanding performance. To date, perovskite solar cells (PSCs) have shown high power conversion efficiency up to 25.7% and 31.3% for the perovskite-silicon tandem solar cells, which promises to revolutionise the PV landscape. However, the stability of PSCs under operating conditions has yet to match state-of-the-art silicon-based solar cell technology, in which the stability of the absorbing layer and relevant interfaces is the primary challenge. These issues become more serious in the larger area solar modules due to the additional interfaces and more defects within the perovskite. Bilayer perovskite film composed of a thin low dimensional perovskite layer and a three-dimensional perovskite layer shows great potential in fabricating solar cells with high efficiency and stability simultaneously. In this review, recent advancements, including composition design and processing methods for constructing bilayer perovskite films are discussed. We then analyze the challenges and resolutions in deposition bilayer perovskite films with scalable techniques. After summarizing the beneficial effect of the bilayer structure, we propose our thinking of feasible strategies to fabricate high-efficiency perovskite solar modules with a long lifetime. Finally, we outline the directions for future work that will push the perovskite PV technology toward commercialization.

“…In the past decades, organic-inorganic hybrid metal halide perovskite solar cells have attracted great research interests due to their high absorption coefficients in the incident solar spectrum, long carrier lifetime, and high electron-hole mobility. [1][2][3][4][5][6][7][8][9][10][11][12][13] The maximum certified power conversion efficiency (PCE) of perovskite solar cells (PSCs) has achieved 25.5%, coming out top in the field of thin-film solar cells. [14] However, it still falls far short of the theoretical PCE limit of 33.5% for unijunction PSCs.…”

The collaborative strategy of optical design and charge transport dynamics optimization can provide double guarantee to achieve high‐efficient planar perovskite solar cells (PSCs). Herein, WO3−X nanorods with tunable localized surface plasmon resonance (LSPR) effect are introduced at the interface between perovskite and hole transport layer (HTL) via antisolvent method during the preparation of perovskite films. The photocurrent of WO3−X nanorods‐based devices significantly increases due to the extension of absorption region caused by LSPR effect. The charge transfer at the perovskite/HTL interface is also accelerated due to the electromagnetic near‐field enhancement via the LSPR effect. The synchronized improvement in photocurrent and charge transfer by WO3−X nanorods leads to a power conversion efficiency of 21.14% in MAPbI3‐based PSCs. This work not only provides an effective approach to enhance the photovoltaic performance of PSCs, but also demonstrates the potential application of inorganic oxide semiconductors with LSPR in other optoelectronic devices.
