Abstract

The solar energy concentrating system, coupled with an optical fiber, enables us to use highly concentrated solar energy at the desired place regardless of the position of a solar concentrator. We can use it as a heat or light source. This system is also useful for space applications. However, solar energy density decreases from at the end point of the optical fiber, because the transmitted solar light disperses from the exit of the optical fiber according to its numerical aperture. To overcome this problem, we are investigating the CPC(Compound Parabolic Concentrator) coupled to the exit of an optical fiber. This method is capable of increasing the solar energy density. We have experimentally confirmed that the solar energy density from CPC increased 3.5 times as that of an optical fiber bundle output.
