Application of optical fibers to the transmission of solar radiation

Abstract
The application of optical fibers to the transmission of solar radiation is discussed. Attenuations of the extraterrestrial solar radiation spectrum in optical fiber materials, fused‐silica and soda‐lime‐silicate glass, are calculated based on intrinsic attenuation mechanisms. It is shown that fused‐silica‐core optical fibers transmit solar radiation effectively over distances of about 40 m. Possible areas of application of optical fibers to the solar energy utilization systems are suggested.
