“…Even though with this wider bandgap, the designed FPSC delivered an excellent efficiency (i.e., 28 %), and this confirms the possibility of enhancing the FPSC efficiency further (i.e., over 30 %) in the near future using the same proposed device design with various potential perovskite absorbers, including suitable ETL and HTLs, especially with CBz-PAI interlayer. Noticeably, this proposed work comprehensively focused on the perovskite/HTL interface enhancement using CBz-PAI interlayer; however, according to the published reports, mainly using ZnO NWs ETL-based real FPSCs still not exceeding the PCE of 15 % [ 56 ] due to several reasons, such as higher recombinations formed at the ZnO NWs/perovskite interface or the contact between ZnO NWs-ETL into the HTL (i.e., due to larger NWs length or lower perovskite absorber thickness) [ 57 , 58 ], etc. Therefore, further insightful studies are needed, mainly on the ZnO NWs/perovskite interface using passivation/interlayer similar to this study to enhance the FPSC efficiency further.…”

“…[1][2][3] It also has excellent chemical and thermal stability, low cost and high flexibility that allows synthesizing different nanostructures such as nanorods, nanowires, nanocolumns, etc. [2,4,5] The above properties make it possible to use in promising applications like sensors, [6,7] antimicrobial activity, [8,9] photocatalysis, [10][11][12] solar cells, [13,14] liquid crystals, [15] etc. The addition of dopant elements [16][17][18] in ZnO host material leads to tailor its optical, structural, electric and magnetic properties improving device applications.…”

ZnO films were obtained by electrodeposition technique from commercial Zn2+ solutions and those obtained from spent alkaline batteries. The type of counterion and pH impact directly on the structural, morphological, and optical properties of the electrodeposited ZnO films. The morphological and crystallographic orientation differences observed by X‐ray diffraction (XRD) analysis and high‐resolution field emission scanning electron microscopy (HR‐FESEM), demonstrates the influence of the type and origin of precursors used in the ZnO synthesis process. Those samples grown from commercial nitrate solutions exhibit nanocolumns revealing a preferential growth in the (002) direction. On the other hand, random growth (hexagonal plates, agglomerations, clusters, etc.) is observed in samples obtained through recycled solutions. All deposited samples achieved a transparency close to 80 % and an optical band gap of around 3.30 eV. The as‐deposited films were evaluated toward the photodegradation capacity of methylene blue (MB) for potential technological applications. Results exhibit that samples prepared from recycled ZnCl2 solutions presented more than 80 % degradation per mass of ZnO. This work demonstrates a virtuous circle since ZnO films are deposited by a facile and scalable technique from discarded batteries and used for MB photodegradation. Furthermore, the simplicity of recovery of these substrates after application makes them an attractive and pragmatic option for a range of water treatment applications. Synopsis: Zinc from depleted alkaline batteries is reused to obtain ZnO thin films that remove contaminating dyes from water.

Perovskite solar cells (PSCs) have gained tremendous research interest recently owing to several advantages, including low material cost, facile solution processability, bandgap tunability, and alluring device efficiency. The organic formamidinium (FA) cation‐based perovskites are mainly considered as one of the potential candidates for charge carrier generation due to their excellent properties, such as bandgap and thermal stability than traditional perovskites. However, the inevitable unfavorable polymorphism (i.e., α to δ) at room temperature still forms the basis for numerous research works to allow the fabrication of a high‐quality absorber and enhances the PSCs performance. The studies to resolve the polymorphism and several contemporary techniques (e.g., passivation strategy) with several recent novel fabrication methods presented in this review form the essence of the improvements in PSCs. The absorber morphology also influences the charge‐transfer behavior and the device's lifetime. Therefore, understanding these properties is essential to improve the absorber quality and avoid many defects. This review focuses on the structure and properties of pure and mixed FA perovskites with various halides, mainly the FA cation's role in the absorber composition. And a comprehensive overview of recent FA cation‐based double, triple, and quadrupole PSCs results with proper scientific explanations to understand the device physics.
