Nanostructures exhibit excellent antireflection (AR) properties allowing for broadband antireflection and increasing the light incoupling in solar cells. In this paper, the optical effect of different nanostructures on the front side of an organic-inorganic halide perovskite semiconductor solar cell is studied. The transfer matrix optical simulation method (TMM) will be used to model and simulate the solar cell while using the effective medium theory (EMT) to model the effective refractive indices of the nanostructures. By optimizing the height of each nanostructure, it was found that the moth-eye nanostructure had the best performance, reducing the reflection by ~ 7.8%, thus enhancing the optical current density by ~ 13.5% and increasing the overall efficiency by 2.22%. Additional optical analysis methods were used to analyze and characterize the effect of the added AR nanostructures such as the solar-weighted reflectance (SWE), the solar absorptance enhancement (SWR), current density loss analysis ( J loss ), and finally, the spectral photovoltaic output (SPV).

“…As the front windows of f-PSC devices, considerable optical reflection on the surface of conventional polymers regularly causes the depressed photonic collection and efficiency of devices. A variety of reports adopted antireflection strategies to enhance photovoltaic efficiency. − A PDMS antireflection layer was equipped on the surface of an ITO-coated Willow glass substrate . Devices containing optimal inverted cone structures revealed negligible reflection and high absorption in contrast to those without antireflection layers (Figure c).…”

Flexible Perovskite Solar Cells: From Materials and Device Architectures to Applications

Perovskite solar cells (PSCs) are being rapidly developed at a fiery stage due to their marvelous and fast-growing power conversion efficiency (PCE). Advantages such as high PCE, solution processability, tunable band gaps, and flexibility make PSCs one of the research hot spots in the energy field. Flexible PSCs (f-PSCs) owing to high power-to-weight ratios can be promising candidates to serve as power sources in mobile energy systems, space energy systems, portable functional devices, and so on. Herein, we give a review on recent progress in f-PSCs involving flexible substrates and flexible transparent electrodes, performance enhancement by optimizing functional layers, large-scale fabrication techniques, flexibility promotion strategies, and their potential applications. Furthermore, perspectives are discussed on the future development of f-PSCs.

“…In addition, MOFs can be used to fabricate a variety of structures with highly tunable pore size (typically 0.4-6 nm) and surface area (500-4500 m 2 /g) through the use of different metal groups and numerous or-ganic compounds. Controlling the penetration of the framework can lead to different MOF configurations, porosities, and functionalities [36][37][38][39][40][41][42]. By changing the efficient parameters of the synthesis processes or by applying other methods, the size of the particles can also be determined.…”

Antiproliferative and Apoptotic Effects of Graphene Oxide @AlFu MOF Based Saponin Natural Product on OSCC Line

et al. 2022

The increasing rate of oral squamous cell carcinoma (OSCC) and the undesirable side effects of anticancer agents have enhanced the demand for the development of efficient, detectable, and targeted anticancer systems. Saponins are a diverse family of natural glycosides that have recently been evaluated as an effective compound for the targeted therapy of squamous cell carcinoma. Due to their porous nature and stable structure, metal–organic frameworks (MOFs) are a well-known substance form for various biological applications, such as drug delivery. In this study, we fabricated a novel hybrid, highly porous and low-toxic saponin-loaded nanostructure by modifying graphene oxide (GO)/reduced GO (rGO) with aluminum fumarate (AlFu) as MOF core–shell nanocomposite. The characterization of the nanostructures was investigated by FTIR, TEM, EDX, FESEM, and BET. MTT assay was used to investigate the anticancer activity of these compounds on OSCC and PDL normal dental cells. The effect of the nanocomposites on OSCC was then investigated by studying apoptosis and necrosis using flow cytometry. The GO/rGO was decorated with a saponin–AlFu mixture to further investigate cytotoxicity. The results of the MTT assay showed that PDL cells treated with AlFu–GO–saponin at a concentration of 250 μg/mL had a viability of 74.46 ± 16.02%, while OSCC cells treated with this sample at a similar concentration had a viability of only 38.35 ± 19.9%. The anticancer effect of this nanostructure on OSCC was clearly demonstrated. Moreover, the number of apoptotic cells in the AlFu–GO–saponin and AlFu–rGO–saponin groups was 10.98 ± 2.36%–26.90 ± 3.24% and 15.9 ± 4.08%–29.88 ± 0.41%, respectively, compared with 2.52 ± 0.78%–1.31 ± 0.62% in the untreated group. This significant increase in apoptotic effect observed with AlFu–rGO–saponin was also reflected in the significant anticancer effect of saponin-loaded nanostructures. Therefore, this study suggests that an effective saponin delivery system protocol for the precise design and fabrication of anticancer nanostructures for OSCC therapy should be performed prior to in vivo evaluations.
