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.
