摘要

Polymethyl methacrylate (PMMA) plate luminescent solar concentrators with a bottom-mounted (BM-LSCs) photovoltaic (PV) cell are fabricated by using a mixture of Lumogen Red 305 and Yellow 083 fluorescent dyes and a commercial monocrystalline silicon cell.The fabricated LSC with dye concentrations of 40 ppm has the highest power gain of 1.50,which is the highest value reported for the dye-doped PMMA plate LSCs.The power gain of the LSC comes from three parts:the waveguide light,the transmitted light,and the reflected light from a white reflector,and their contributions are analyzed quantitatively.The results suggest that the BM-LSCs have great potential for future low-cost PV devices in building integrated PV applications.
