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.
Studies have shown that fiber optics can be used in order to achieve a concentration of solar energy. Light can be transmitted through the optical fibers and concentrated in a useful and efficient way of handling solar energy.
Conclusions A combined solar fiber lighting and photovoltaic power generation system based on spectral splitting (SSLP) technology has been proposed in this study, with visible light for house lighting and near-infrared light for photovoltaic power generation.
The optical fibers need to pass through the building from outdoor to indoor, and it is inevitable to move and bend under the rotation of the solar tracking platform. The PMMA optical fibers are with good flexibility and low cost, can meet these requirements.
Photovoltaic power generation device The near-infrared sunlight reflected by the spectral beam splitter is used for photovoltaic generation. The PV cells will be overheated by the concentrated infrared light, and high temperature is unfavorable for the PV power generation.
The experimental results show that the sunlight transmitted to the room through the optical fiber is bright and comfortable, with an average lighting efficiency of 15.1 %; meanwhile, the average power generation efficiency is about 6.1 %. The power generation efficiency of the system can reach to one-third of that of conventional PV modules.
