Abstract：Photovoltaic power generation is one of the most efficient ways to utilize solar energy. In this paper, a type of planar waveguide-based luminescent solar concentrator with a surface area of 50 mm×50 mm and a height of 5 mm is fabricated by coating a layer of Rhodamine 6G-doped PMMA on a clean PMMA substrate. The thickness of the Rhodamine 6G-doped PMMA layer is 32 m. The influence of the concentration of Rhodamine 6G on the concentration ratio and photovoltaic properties has also been investigated. The results have shown that the concentration ratio and the photovoltaic properties reach 0.45 and 0.49%, respectively when the concentration of of Rhodamine 6G is 0.250%.
