Summary: A bilayer antireflective coating has been designed to reduce photon loss and increase the efficiency of perovskite solar cells by enhancing glass transmittance. By adjusting the refractive index and film thickness of each layer, significant improvements in short-circuit current density and power conversion efficiency can be achieved. This simple yet effective strategy can be applied to enhance the efficiency of various types of solar cells.

Summary: In this study, the electron beam vacuum coating method was used to coat a SiO2 film on an MgAl2O4 spinel substrate. The coated silica had a thickness of 880 nm, close to the aimed theoretical thickness, and a roughness of 2.11 nm. It significantly enhanced the transparency of the spinel substrate. The infrared transmittance of the coated sample was measured to be 92.5% to 78.5% in the range of 3700 nm-4800 nm, showing an improvement of 2%-4% compared to the MgAl2O4 spinel. The bonding force between the coating and the substrate was determined to be about 200 MPa. These findings are important for the precise design and production of antireflection coatings on transparent materials.

Summary: Antireflective coatings were fabricated using charged chitin nanofibers (ChNFs) through layer-by-layer self-assembly. The thickness and refractive index of the ChNF coatings could be controlled by adjusting the concentration of the ChNF suspensions and number of bilayers, resulting in improved transmittance. This study demonstrates the potential of charged ChNFs as building blocks for efficient and cost-effective fabrication of antireflective coatings on large size substrates.

Summary: Pyramidal antireflective structures were fabricated by hot embossing of an amorphous GcSe(4) optical element on both single- and double-sides. The transmittance was significantly improved, reaching up to 75.6% and 79.8% for single and double-side embossing, respectively. Experimental results showed good agreement with simulation using rigorous coupled-wave analysis (RCWA), and theoretical models successfully predicted the transmittance changes with incident angle. A new Fabry-Perot interferometer structure composed of two single surface embossed samples was proposed.

Summary: With the development of silicon-based photonics, silica and silicon nitride anti-reflection coatings with tunable refractive index were deposited by ion-assisted reactive magnetron sputtering. The optimized coatings exhibited average reflectance of 0.74% for single-layer and below 0.35% for multi-layer coatings. These coatings have broadband low reflectance and high deposition quality, making them suitable for optical communication devices.

Summary: Assemblies of single-walled carbon nanotubes with specific chiral structures are highly promising optofunctional materials due to their strong light-matter coupling and selectivity in optical resonances. However, the lack of research on the complex optical spectra of single-chirality carbon nanotube assemblies has hindered their application in device design. In this study, we experimentally determine the broadband complex refractive index spectra of single-chirality carbon nanotube assemblies, providing valuable insights for the design of photonic devices using carbon nanotubes as the material.
