“…A typical Tyndall effect of p-g-C 3 N 4 colloidal suspension is clearly evident, as indicated by the beam passing through the transparent sol solution. According to our previous research work, 14 the MAPbBr 3 microparticles (with an average size of about 5 mm) become rougher due to the wrapped/entrapped p-g-C 3 N 4 nanosheets in Fig. 2a and b.…”

“…Because of the ionic migration nature, the inherent instability issues of organic halide perovskites make them generally incompatible with typical photocatalytic reactions in aqueous media. Therefore, special organic alcohol-catalyzed substitutional growth processes 13,14 and polymer modication 15 were used to prepare highly air (up to z1.5 months), thermally and chemically stable halide perovskites with unique surface chemical states. In particular, large MAPbBr 3 microcrystals were fabricated through an isopropanol-assisted solvothermal method in our previous report.…”

Two phase photocatalysts can be intergrown with each other, resulting in superior photocatalytic properties. Herein, methylamine lead bromide (MAPbBr 3 ) wrapped/entrapped protonated graphitic carbon nitride (p-g-C 3 N 4 ) intergrowth microcrystals were fabricated by mixing a pervoskite precursor with p-g-C 3 N 4 colloidal sol. A highly stable isopropanol (IPA) solvent based photocatalytic system for dye degradation was demonstrated. The composite with an optimal p-g-C 3 N 4 mass percentage of 3.3 wt% (denoted as MAPbBr 3 /p-g-C 3 N 4 -1.0 mg) exhibited the highest photocatalytic degradation of malachite green (99.8%) within 10 min under visible light, which was 5.3-fold and 16-fold greater than that exhibited by its constituents separately. The strong chemical interaction and fundamental photophysical processes in MAPbBr 3 /p-g-C 3 N 4 were systematically evaluated by spectroscopic and electrochemical techniques, confirming the effective separation of photogenerated electron-hole pairs and faster interfacial charge transfer behavior. Furthermore, active superoxide radicals (O 2 c À ) played a vital role in the catalytic reaction, because of the significant photoinduced electron transfer rate (k et ) in the inverted type-I core/shell MAPbBr 3 /p-g-C 3 N 4 band configuration structure. In addition, MAPbBr 3 /p-g-C 3 N 4 has good cycling stability for 10 cycles and versatility for other cationic (RhB) and anionic (MO) dye pollutants, indicating the great potential for solar energy conversion into chemical energy.

Halide perovskites, traditionally a solar-cell material that exhibits superior energy conversion properties, have recently been deployed in energy storage systems such as lithium-ion batteries and photorechargeable batteries. Here, recent progress in halide perovskite-based energy storage systems is presented, focusing on halide perovskite lithium-ion batteries and halide perovskite photorechargeable batteries. Halide-perovskitebased supercapacitors and photosupercapacitors are also discussed. The photorechargeable batteries and photorechargeable supercapacitors employ solar energy to photocharge the battery; this saves energy and improves device portability. These lightweight, integrated halide perovskite-based systems, which are pertinent to electric vehicles and portable electronic devices, are reviewed in detail. Suggestions on future research into the design of halide-perovskite-based energy storage materials are also given. This review provides a foundation for the development of integrated lightweight energy conversion and storage materials.

“…It was found that bromide plays a crucial role in lithium intercalation and storage capacities of ≈375 and ≈500 mAh g –1 were observed in (CH 3 NH 3 ) 2 (CH 3 (CH 2 ) 2 NH 3 ) 2 Pb 3 Br 10 and MAPbBr 3 , respectively . Recently, Wang et al demonstrated excellent cyclic stability (1000 cycles) in MAPbBr 3 ‐based batteries . Besides these achievements, rapid deterioration of the electrode is still a major obstruction in commercializing these materials in a battery.…”

An insight into the analogies, state-of-the-art technologies, concepts, and prospects under the umbrella of perovskite materials (both inorganicorganic hybrid halide perovskites and ferroelectric perovskites) for future multifunctional energy conversion and storage devices is provided. Often, these are considered entirely different branches of research; however, considering them simultaneously and holistically can provide several new opportunities. Recent advancements have highlighted the potential of hybrid perovskites for high-efficiency solar cells. The intrinsic polar properties of these materials, including the potential for ferroelectricity, provide additional possibilities for simultaneously exploiting several energy conversion mechanisms such as the piezoelectric, pyroelectric, and thermoelectric effect and electrical energy storage. The presence of these phenomena can support the performance of perovskite solar cells. The energy conversion using these effects (piezo-, pyro-, and thermoelectric effect) can also be enhanced by a change in the light intensity. Thus, there lies a range of possibilities for tuning the structural, electronic, optical, and magnetic properties of perovskites to simultaneously harvest energy using more than one mechanism to realize an improved efficiency. This requires a basic understanding of concepts, mechanisms, corresponding material properties, and the underlying physics involved with these effects. His current research focuses on developing functional inorganic−organic hybrid materials and energy conversion devices including perovskite solar cells.are found to have lower t-values (0.75 < t < 1.0). t-values help in governing and tuning the presence of ferroelectricity in perovskites [11] and are responsible for the transition temperatures in ferroelectrics. [57] In the case of hybrid inorganic-organic perovskites, the A-site and/or X-site ions are replaced by molecular building blocks; hence, the tolerance
