Abstract
The invention relates to high efficiency solar collection devices having a matte surface, a low refractive index surface, or both, that increases solar radiation transmission into the device. The matte surface is on a thermoplastic and may be provided in many ways, such as by a matting agent, by the use of a matte chill roll, embossing, or other techniques. The matte and/or low refractive index surface may be a coating, film (single or multi-layer) or sheet (single or multi-layer). The invention is especially useful in both rigid and flexible photovoltaic modules.
Claims8
A high efficiency solar collection device comprising an external, translucent fluoropolymer-based thermoplastic glazing material having an average light transmittance of 95% or more when measured by a Perkin Elmer Lambda 19 Spectrometer using standard transmittance scan from 250 nm-1800 nm, with an integrating sphere over a range from 400 nm to 1100 nm wavelength, wherein the external surface of the fluoropolymer thermoplastic glazing has a matte surface, said matte surface having an Ra of less than or equal to 0.381 micrometers, wherein said fluoropolymer is a polyvinylidene fluoride-based homopolymer or copolymer, and wherein said translucent fluoropolymer-based thermoplastic glazing has a haze as determined by ASTM D1003 of greater than 50 percent.
