With fast transient response, the emulator responds to change in load conditions and maintains the output on IV characteristics of the panels defined by user for a given ambient condition. It is a flexible instrument designed to emulate the output of solar panels, with adjustable parameters such as Voc, Isc, shading, coefficient of temperature etc.
Vary the input power to your light source or the distance between light source and sample stage, until the desired power density is achieved. For normal spectral conditions, this should be 1 Sun = 1000 W/m 2 = 100 mW/cm 2 The complexity of the control elements you need for a solar simulator will depend on the type of light source you are using.
The most vital part of a solar simulator is, of course, the light source. However, solar simulators can be assembled with several other components to bring the simulated spectrum closer to the solar spectrum and ensure that this light is uniformly distributed across the defined test area.
Most solar simulator lamps require a constant-current (DC) power supply to provide temporally stable irradiance. For example, variations in power supply to an LED lamp can result in lamp flickering, which compromises the short-term instability of the light source.
The main component of a solar simulator is the calibrated light source. The most commonly used light sources are Xenon arc lamps, but the development of high intensity LEDs has meant that LED solar simulator lamps are becoming more popular. LED light sources have longer lifetimes than their arc lamp alternatives.
The arrangement of a solar simulator is quite simple: the light source is directed towards a test area, and the irradiance over that test area should meet the defined standards. It is therefore important to make sure that your light source is at the correct distance from your sample.
