Anti Reflective coating in solar cell

The first group is made up of AR coatings that target one or more broad wavelength bands. Our BARC coatings are examples of this group.

Photons falling onto a semiconductor material can be divided into three groups based on their energy compared to that of the semiconductor band gap.

Anti reflective coating spray

This broadband anti-reflective (AR) coating is particularly designed for telecommunication applications. It provides a low level of reflectance to less than 0.25% average from 1450-1650nm. Standard & custom coatings are available for refractive indices of 1.46-1.90.

Norland Optic Adhesives are clear, one part adhesives that contain no solvents. When exposed to UV light, they gel in seconds and cure fully in minutes to give a tough resilient bond. Each of the six formulas listed below has been optimized to provide excellent bonding for specific applications. To cure these optical adhesives, they must be exposed to UV light.

This high efficiency broadband anti-reflective (AR) coating reflects less than 0.5% average from 425-675nm. Higher performance specifications are also available. Standard & custom coatings are available for refractive indices of 1.46-1.90.

These Anti-Reflective (AR) coatings are all dielectric, single or multi-layers, and are designed for low reflectance and high transmittance in the UV, visible, and near IR spectral bands. AR coatings meet the requirements of MIL-C-675C, MIL-C-14806A, and MIL-C-48497A. AR Coatings are often crucial components in optical systems with multiple lenses or other optics where the maximum possible light energy is needed. AR coatings help to produce brighter images while reducing the intensity of ghost images which may otherwise be produced in optical systems having multiple reflecting surfaces.

This narrow band anti-reflective (AR) is an excellent coating for targeting a single wavelength or very narrow band of wavelengths at or near 1550nm. Standard < 0.25% and high performance < 0.05% reflectivity specifications are available.
