CONCLUSIONS The major finding of the current analysis is that the use of optical fibers in solar thermal concentrating systems for power generation is feasible, but only under specific circumstances. The main point to watch is minimizing the amount of fibers used in the system, since this is a significant cost driver.
Optical fibers have a range of commercial applications, notably in communication and lighting. Fibers consist of a coaxial arrangement of a core that serves as the light conduit, a cladding of a lower refractive index to provide internal reflection at the boundary of the core, and an external protective sheet.
The optical fiber used to build this light guide is the anhydroguide PCS low OH Vis-IR fiber. It is a cost effective alternative to fused silica clad fibers. It has a broad operating wavelength range from 400 to 2400 nm. This fiber has a high numerical aperture of NA=0.4, which allows an efficient collection of solar energy.
Data and power channels were multiplexed and launched into a 10 m-long optical fiber and power delivered was done by using a laser operating at wavelength 405 nm and the data signal was transmitted at wavelength 650 nm.
With the present day availability of fiber-optic techniques, solar energy can be transmitted by high-quality optical fibers of large core diameter and large numerical aperture.
The estimate of the dependence of the output optical power on the length of the fiber connected with optical splitters for input optical power for HPLS set to 8.0 W is shown in Fig. 14 a. The figure shows that the output of the optical energy of the splitter (distance 0 m in the X-axes) is 3.10 W for Pout1 and 3.30 W for Pout2.
