5. Conclusion
In this paper, four single-color (red, green, blue, white) LED solar
simulators and one red-green-blue simulator, all having high irradiance,
are constructed. High irradiance is achieved by pulsing LEDs
with high input voltages. Irradiance uniformity and instability
qualify the five simulators as Class B. Solar cell electrical parameters
and resistances using these simulators are made. Applying
correction methods recommended in the IEC 891 Standard, for IeV
characterization at non-STC, results on electrical parameters and
resistances measured with the red and blue LED simulators and the
Class AAA simulator are in good agreement
