Abstract
The present disclosure generally relates to broadband antireflective coatings for reducing reflection of light in the infrared without compromising visible light reflectance in multijunction solar cells bonded to coverglass, and methods of forming the same. The antireflective coatings include a high index, one or more intermediate index, and low index of refraction dielectric layers. The high index dielectric layer utilizes an ion beam assisted deposition to maximize the density and index of refraction. The intermediate index layer(s) increase the bandwidth of the antireflection coating, thereby improving the performance of the antireflective coating in the infrared spectrum.
