Summary: The study utilized wavelength and angle resolved scattering (WARS) reflectance measurements on b-Si surfaces to analyze light scattering effects. It was found that large angle scattering occurs across the entire spectrum, especially for shorter wavelengths and taller texture features, resulting in significant light trapping through total internal reflectance (TIR) at various interfaces. This led to a calculated additional boost of up to 0.45% in the photogenerated current of encapsulated black silicon solar cells.

Summary: Aqueous supercapacitors are considered promising for commercial energy storage devices due to their safety, low cost, and environmental friendliness. However, the challenge of achieving both long electrode lifespan and qualified energy-storage property has hindered their practical application. In this study, an electrode-electrolyte integrated optimization strategy is developed to meet real-life device requirements. By optimizing the nanomorphology and surface chemistry of the tungsten oxide anode, along with the design of a hybrid electrolyte, record-breaking durability and stable operation under extreme conditions are achieved. These results demonstrate the possibility of replacing commercial organic energy storage devices with aqueous counterparts for various daily applications.

Summary: In this investigation, two-dimensional (2D) layered perovskite single crystals with a vertical gradient band gap were successfully synthesized using a solid-state halide diffusion process. The crystal and morphology of the synthesized crystals remained intact, as confirmed by X-ray diffraction (XRD) and scanning electron microscopy (SEM) measurements. The formation of a vertical gradient band gap was observed through transmittance and photoluminescence (PL) spectra, and was attributed to the gradient halide distribution achieved via halide intermixing. The synthesized mixed halide crystals exhibited high stability and enhanced carrier transport, making them suitable for various applications that require vertical carrier transport. The halide diffusion behavior was found to be different from the previously proposed layer-by-layer diffusion model in exfoliated crystals.

Summary: We demonstrate enhanced self-phase modulation (SPM) in silicon nitride (Si3N4) waveguides integrated with two-dimensional graphene oxide (GO) films. The use of a solution-based, transfer-free coating method allows precise control of the film thickness. The hybrid waveguides show significantly improved spectral broadening due to the high Kerr nonlinearity of GO, achieving a broadening factor of up to 3.4. The experimental results show an improvement in the waveguide nonlinear parameter by a factor of up to 18.4 and a Kerr coefficient (n(2)) of GO that is about 5 orders of magnitude higher than Si3N4. Theoretical analysis is provided for the influence of GO film length, coating position, and saturable absorption on the SPM performance.
