“…Being mindful of the facts, researchers worldwide focus on effective energy conversion and storage systems. 1 On the midst of an energy, storage system is the uninterrupted prevalence of Li-ion batteries (LIBs), even though several other alternatives have been proposed. 2 It stems from the reality that the science behind the LIBs is much well known compared to the recent ones.…”

The tavorite-structured materials remain unfathomed as positive electrodes in rechargeable batteries. Reasoning of this fact, borate, and silicate-based tavorites are investigated for utilization in Li-ion batteries (LIBs) and as a photocatalyst for organic contaminant degradation. The physiochemical, electrochemical, dielectric, and photoelectrochemical properties are analyzed to learn the fact that LiVBO 4 F has resulted in a glass-ceramic nature owing to the embodiment of boron oxyfluoride glasses. This nature has made them effective as cathodes even under sensitive mode operations compared to their counterpart. Additionally, a multiredox behaviour was witnessed for both the materials, which boosts the specific capacity for LIB system. Besides, LiVSiO 4 F display immense degradation efficiency for tetracycline, an organic contaminant. These materials unveil expedient properties, promising its multiple usage in the field of conversion cum storage devices as photoelectrodes and cathodes in LIBs.

abundant renewable energy source, the solar-rechargeable electric energy storage systems (SEESSs), which convert solar radiation to electricity via the PV components while the complementary ESSs directly store the as-generated electrical energy, is one of the most promising nextgeneration power sources. [5][6][7] Considerable research efforts have been devoted to the development of high-performance SEESSs to meet the diverse energy demands, which require both high power density and high energy density. [4,8] However, the state-of-the-art SEESSs consisting of photovoltaics and lithium-ion batteries (LIBs) have fundamental limitations such as low power density (Scheme 1a) and poor energy storage efficiency (ESE) under high charge-discharge rate because of the limited rate performance of LIBs. [4,5] For example, the energy density and ESE of a LIB only retain less than 50% and 60% of its original values when the current density increases from 85 to 850 mA g −1 . [9] To address these issues, much effort has been made to exploring combination of PVs with supercapacitors (SCs), which show excellent power density. [10][11][12] Nonetheless, the PVs-SCs systems still face a number of challenges including the low operation voltage (mostly below 0.8 V), and more critically, limited energy density (usually lower than 15 Wh kg −1 , Scheme 1a). [13,14] The emerging aluminum ion batteries (AIBs) showing fast chargedischarge feature provide a new avenue to achieve both high power density and large energy density, leading to constantly high ESE under ultrahigh charge-discharge rates. [15] Other important merits such as abundant Al resources, increased safety, and long cycling stability together make AIBs promising energy storage candidates for portable SEESSs, but their use for next-generation SEESSs has yet been reported. [16][17][18][19] In addition to the improvement of energy storage part, optimized modulation is also urgently required for the portable SEESSs, to achieve higher overall photoelectric conversion and storage efficiency (PCSE). [20] One major obstacle in achieving efficient solar-charging is the incompatible current-voltage characteristics between multi-junction PVs and ESSs. [21] The mismatch between the maximum power point (MPP) of PV and charge voltage of ESS results in significantly reduced solar to battery charging efficiency and thus a lower overall PCSE. [11] Furthermore, the external electrical circuit connecting the PVs The solar-rechargeable electric energy storage systems (SEESSs), which can simultaneously harvest and store solar energy, are considered a promising next-generation renewable energy supply system. However, the difficulty in meeting the demands of higher overall photoelectric conversion and storage efficiency (PCSE) with both high power density and large energy density in the current SEESSs severely limit their practical application. Herein, a new class is demonstrated of portable and highly efficient SEESS that uniquely integrates a perovskite solar module (PSM) and an aluminum-ion batter...

Interface engineering is critical to the development of highly efficient perovskite solar cells. Here, urea treatment of hole transport layer (e.g., poly(3,4-ethylene dioxythiophene):polystyrene sulfonate (PEDOT:PSS)) is reported to effectively tune its morphology, conductivity, and work function for improving the efficiency and stability of inverted MAPbI 3 perovskite solar cells (PSCs). This treatment has significantly increased MAPbI 3 photovoltaic performance to 18.8% for the urea treated PEDOT:PSS PSCs from 14.4% for pristine PEDOT:PSS devices. The use of urea controls phase separation between PEDOT and PSS segments, leading to the formation of a unique fiber-shaped PEDOT:PSS film morphology with well-organized charge transport pathways for improved conductivity from 0.2 S cm −1 for pristine PEDOT:PSS to 12.75 S cm −1 for 5 wt% urea treated PEDOT:PSS. The urea-treatment also addresses a general challenge associated with the acidic nature of PEDOT:PSS, leading to a much improved ambient stability of PSCs. In addition, the device hysteresis is significantly minimized by optimizing the urea content in the treatment.order to overcome the reactivity issue of the acidic PEDOT:PSS with the plastic substrates. Therefore, we expect this technology to be expanded for addressing the stability and performance issues of perovskite solar cells.
