Determination of solar cell electrical parameters and resistances using color and white LED-based solar simulators with high amplitude pulse input voltages
Advances in LEDs allow construction of LED solar simulators for characterization of solar cells at moderate costs. Four single-color LED simulators and one multi-color LED simulators are constructed. High irradiance is obtained by employing high pulsing voltages to LEDs. Using the simulators electrical parameters and resistances of solar cell are made. Applying correction methods recommended in the IEC 891 Standard, results from the red and blue LED simulators and the Class AAA simulator are in good agreement.
