Optical efficiency and optical properties of luminescent solar concentrators

Three luminescent solar concentrators (LSCs) samples have been prepared using BASF- 241, 402 and 339 dyes dissolved in methylmethacrylate (MMA) and thermally polymerized. The optical efficiencies were measured and calculated hourly through the year (1996-7) considering day 22 as the reference day for each month. The optical absorption measurements have been carried out at room temperature before and after the samples were exposed to daylight. The optical absorption edges were analysed and the photostability of the samples tested. (C) 1998 Elsevier Science Ltd. All rights reserved.
