The spectroscopic properties of 1,4,170 and 750 oxazine dyes doped in polymethyl methacrylate (PMMA) were measured and studied. The photostability of these samples were outdoor tested during the four seasons. The optical efficiency of luminescent solar concentrator (LSC) of 750 oxazine dye was measured and calculated hourly for one year (1995–1996) considering day 21 as a reference day for each month. The performance of LSC has been tested at three different positions using X-Y tracker.
