Abstract: Polymeric multilayer optical films are described. More particularly, polymeric multilayer optical films having a first optical packet and a second optical packet are described. The second optical packet is disposed on the first optical packet. How the configuration of the layers of the optical packets affect hemispheric reflectivity of the overall film is also described. The polymeric multilayer optical film reflects more than 95% of light from 400 nm to 700 nm at normal incidence.

Abstract: Multilayer infrared (IR) reflecting films are provided. An optical repeating unit of the film include a plurality of optical polymeric layers arranged to reflect light by constructive and destructive interference. Optical layer A is a high refractive index polymeric layer, and optical layer B is a low refractive index isotropic polymeric layer containing fluoropolymers. The film has an average reflectance of about 50% to about 100% in a near infrared wavelength range of about 850 nm to about 1850 nm, and an average transmission of about 70% to about 90% in a visible light range.

Abstract: Broadband reflectors include a UV-reflective multilayer optical film and a VIS/IR-reflective layer. In various embodiments, the VIS/IR reflective layer may be a reflective metal layer or a multilayer optical film. Concentrated solar power systems and methods of harnessing solar energy using the broadband reflectors and optionally comprising a celestial tracking mechanism are also disclosed.
