Indoor solar cell test and characterization system which is able to simulate a variety
of indoor light color and light intensity (200lux~10000 lux; 0.00005sun~0.025sun;
0.05 W/m2~ 25W/m2; 0.005mW/cm^2~2.5 mW/cm^2. Continuously adjustable),
spectrum, high non-uniformity(≦±2%) and large illumination area(> 250x250mm^2; customized).
Traceable to light intensity calibrated devices, is able to accurately evaluate the indoor use of solar
cell conversion efficiency.
