We report conversion efficiencies of experimental single and dual light guide luminescent solar concentrators. We have built several 5cm×5cm and 10cm×10cm luminescent solar concentrator (LSC) demonstrators consisting of c-Si photovoltaic cells attached to luminescent light guides of Lumogen F Red 305 dye and perylene perinone dye. The highest overall efficiency obtained was 4.2% on a 5cm×5cm stacked dual light guide using both luminescent materials. To our knowledge, this is the highest reported experimentally determined efficiency for c-Si photovoltaic-based LSCs. Furthermore, we also produced a 5cm×5cm LSC specimen based on an inorganic phosphor layer with an overall efficiency of 2.5%.
