“…[26] The electrocatalytic performance of the CE in DSSCs can be improved by using different materials, crystal-lization, and fabrication methods. [27] Although, Pt has shown excellent performance in the development of high performance DSSCs but high cost and preciousness of Pt restricted its practical application. [28] Therefore, it is of great significance to replace the Pt from DSSCs using low cost and environmentalfriendly counter electrode materials.…”

Recently, design and fabrication of platinum free counter electrodes have received enormous attention of the scientific community. In this work, we have fabricated manganese dioxide/reduced graphene oxide (MnO2@Gr) counter electrode based DSSCs. Hydrothermal method was utilized for the synthesis of MnO2@Gr. Further, X‐ray diffraction technique (XRD), scanning electron microscopy (SEM), and energy dispersive X‐ray spectroscopy (XPS) were employed as physiochemical characterization technique. Surface structural investigations showed that MnO2 has rods like surface morphology which are attached with Gr. The fabricated DSSCs demonstrated good open circuit voltage (Voc) and reasonable efficiency of 0.72 V and 5.87 %, respectively.

This work presents the preparation of inorganic–organic hybrid nanocomposites, namely three-dimensional polyaniline (Pani)/activated silica gel (ASG) (3D Pani@ASG), their characterization, and in removing application as a potential adsorbent for cationic brilliant green (BG), crystal violet (CV), and anionic Congo red (CR), and methyl orange (MO) dyes. Pani@ASG nanocomposites have been prepared by the in situ polymerization method and characterized using various techniques such as Fourier transform infrared (FTIR), X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) with selected area electron diffraction, thermogravimetric analysis with derivative thermogravimetry, zeta potential analyses, and Brunauer–Emmett–Teller (BET). The scanning electron microscopy (SEM) study confirms the average particle size of the Pani@ASG nanocomposite is in the range of 5 nm. FESEM, TEM, FTIR, and XRD analysis proved the successful decoration of ASG over Pani. The BET result of Pani@ASG shows a mesoporous nature with a pore diameter of less than 3 nm and a surface area of 423.90 m2 g–1. Both SEM and TEM analyses show the proportional distribution of ASG over Pani’s surface. The adsorption trend of BG and MO on the studied materials at pH 7 was found as follows: Pani@ASG > Pani > ASG. The highest sorption capacities of MO and BG on Pani@ASG were 161.29 and 136.98 mg/g (T = 298.15 K, and Pani@ASG dose: 0.04 g for MO and 0.06 g for BG), which were greater compared with bare Pani and bare ASG, respectively. The interaction mechanism behind the adsorption of BG and MO dyes onto the Pani@ASG nanocomposite includes electrostatic interaction, π–π interaction, and hydrogen bonding. The mechanistic pathway and the interactions between the targeted dyes and Pani@ASG were further studied using adsorption isotherm, adsorption kinetics, and thermodynamics.

“…Molybdenum selenide (MoSe 2 ) is a typical 2D‐layered semiconductor material, which has a suitable bandgap of about 1.8 eV, excellent electronic structure, high light response, stability, and environmentally friendly. [ 34,35 ] For example, MoS 2 /MoSe 2 [ 36 ] and blue P/MoSe 2 [ 37 ] show an obvious photovoltaic effect compared with pure MoSe 2 . Moreover, the valence band (VB) and conduction band (CB) of MoSe 2 match well with that of the CsSnBr 3 perovskite for the efficient separation of photogenerated electron holes.…”

Sn‐based perovskite materials with nontoxic, low cost, and unique structure have attracted much attention. However, their efficiency only reaches 14.09% due to the higher carrier recombination rate and short carrier lifetime in photovoltaic applications. Herein, the interfacial electronic structure, optical absorption, interfacial charge transfer mechanism, and photovoltaic performance of the CsSnBr3/MoSe2 perovskite heterostructure are systematically investigated by theoretical calculation and experimental observation. The results indicate that the strong coupling and hybridization of interfacial electronic states can lead to a narrowing bandgap, which induces an excellent optical absorption of the CsSnBr3/MoSe2 perovskite heterostructure in the visible spectrum. Excitingly, the charge transfer at the interface forms a built‐in electric field, which can effectively promote the interfacial charge transfer between CsSnBr3 (001) and MoSe2 monolayer, complying with a Z‐scheme mechanism. Moreover, the photovoltaic performance of the CsSnBr3/MoSe2 heterostructure significantly enhances due to excellent light absorption and Z‐scheme system for extending carrier lifetime. An effective strategy for designing highly efficient Sn‐based perovskite solar cells is reported.
