Abstract

High-power light-emitting diodes for application in a solar simulator were evaluated. The solar simulator was designed using only 6 types of high-power LEDs. The irradiance non-uniformity of this simulator was investigated and it was demonstrated that a small array (only 25 units) of selected light-emitting diodes can provide sufficient irradiance to achieve AM1.5G requirements for the test area of at least several cm in diameter without any secondary optics.
