The objective of this review paper is to provide an overview the current state-of-the-art in solar road deployment, including availability anti-reflection and anti-soiling coating materials for photovoltaic (PV) technology. Solar roads are built using embedded PV panels that convert sunlight into electricity, which can be stored later use. Prototypes have been tested on various continents, but ...

An investigation of macrobending loss characteristics of a standard singlemode fiber (SMF28) for small bend radii is presented theoretically and experimentally, which includes the bend loss of the SMF28 with coating layers and the bare SMF28 after stripping the coating layers and chemical etching of partial cladding. The significant influence of reflection occurring at the interface between the...

Broadband anti-reflection (AR) coatings are essential elements for improving the photocurrent generation of photovoltaic modules and enhancing visibility in optical devices. In this paper, we report a hybrid-structured, coating that combines multi-layer thin films with single top-oblique deposited layer. By simply introducing low-refractive index layer, broadband properties can be improved whil...

An anti-reflection coating on a back-illuminated 128 × array Si-based blocked impurity band (BIB) detector in very-long-wave infrared range was designed this work. The reflectance and transmittance spectra of ZnS films with different thicknesses intrinsic Si substrates were studied FDTD simulation experiment. Compared to bare substrate, the coated 1.5, 2.0, 2.5, 3.0 μm thick significantly decre...

Perovskite solar cells have attracted much attention due to their easy fabrication, low cost, and high photoelectric conversion efficiency. To reduce pollution, the absorption layer thickness of perovskite should be reduced. Moreover, ultrathin can effectively depress electron–hole recombination in process carrier transfer. However, light cell is not satisfactory. The promising pathways design ...

Titanium is a key biomedical material due to its good biocompatibility, mechanical properties and corrosion stability, but infections at the implantation site still pose a serious threat. One approach to prevent infection is to improve the antimicrobial ability of the coating material. Silver-doped hydroxyapatite (Ag/HAP) nanoparticles were synthesized by a new modified precipitation method. Th...

Optical design, photon management, and energy conversion efficiency are investigated through numerical simulation of perovskite/silicon tandem solar cell using the single-diode model. A strong near-infrared reflectance roughly 60% is present in perovskite-based top cell. ZnO Si3N4 anti-reflection coating layers placed on surface perovskite layer silicon sub-cell respectively for management mini...
