5/8 Aged at 470 nm Aged at 589 nm Ref. CR0S04 in ethyl acetate after 100 hours irradiation in LED light at 470 and 589 nm. O.D. 1.2 1 0.8 0.6 0.4 0.2 CRS40 in EEE - irradation test 100 hours CRS40 before irradiation CRS40 100 h amber LED CRS40 100 h blue LED 0 200 400 600 Wavelength in nm 800 1000 UV-Vis spectra of CRS040 ethyl acetate solutions before and after LED lamp irradiation for 100 hours kept at room temperature. WP 4.3 Flat Plate Concentrators (FPC) stability testing in 470 nm high intensity LED light The 5 x 5 cm sized flat plate concentrator (FPC) samples received from ECN, 740C, 742C, 747C and 749C were fitted with high efficiency Si-solar cell of 5 x 50 mm size. The sample 74C (yellow colored) was kept in the dark as reference. The 3 other samples were exposed to blue LED intense monochromatic light for over 700 hr, the short-circuit photocurrent of the attached Si-cell, the UV-VIS spectra, the fluorescence (normalized) and the external quantum efficiency were measured periodically over time. For the sample 740C, UV-VIS spectra were only acquired at start of the experience, as this plate was fitted with mirrors on all sides later on for the rest of the time in the LED lamp. The flat plate concentrator samples in the 470 nm LED lamp Sample types: Flat Plate Concentrators (received from ECN) FPC740 - fitted with 3 x 50 mm c-Si cell + mirrors = 0.0045 % L. F Yellow 170 FPC742 (Yellow - not aged in blue LED) = 0.004 % L. F Yellow 083 FPC747 - fitted with 3 x 50 mm c-Si cell = 0.01 % L. F Red 305 + 0.004% L.F. Yellow 083 FPC749 - fitted with 3 x 50 mm c-Si cell = 0.01 % L. F Red 305 + 0.003% CRS 040� The table below show the change of photocurrent for the 3 samples exposed to the 470 nm blue LED light for about 700 hours.
