Abstract
Solid state solvation is employed to reduce self-absorption, a key loss mechanism in Luminescent Solar Concentrator (LSC) devices. For an example materials system consisting of poly(methylmethacrylate), Camphoric Acid Anhydride, and the laser dye 4-(dicyanomethylene)-2-tert-butyl-6-(1,1,7,7,-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) a substantial shift in DCJTB emission energy of 832.2 cm−1 is observed whilst no decrease in fluorescence quantum yield occurs. When extrapolated to an LSC device a 16.1% relative improvement in efficiency is predicted with a potential for 23.1% when employing stronger dielectric additives. For a range of dicyanomethylene based fluorophores the predicted improvement in LSC efficiency is from 17.5% to 24.4%.
