LED Solar Simulator provides illumination approximating natural sunlight (AM1.5G) in the wavelength range of 400 to 1100 nm. It assures controlled and repeatable laboratory conditions of spectral content, spatial uniformity and temporal stability for photo-electrochemical experiments meeting class AAA specification. 

Unlike traditional solar simulator based on Xenon short-arc lamp and metal halide discharge lamp, this concept is using high-power LED technology. 

The sun spectrum is matched using 6 LED wavelengths, sufficiently spaced apart to provide a uniform light.

Common Measurements made in I/V Characterization of photovoltaic devices

Dark I/V measurements are commonly used to analyze the electrical characteristics of solar cells. Dark I/V measurements are more sensitive than light I/V measurements in determining parameters such as series resistance, shunt resistance, diode factor, and diode saturation currents. 

Solar simulator automatically determine the photovoltaic parameters as follows

Open circuit voltage (Voc)

Short Circuit current (Isc)

Fill factor (FF)

Voltage at Pmax (Vmax)

Current at Pmax (Imax) 

Maximum power output (Pmax)

Shunt resistance (Rsh) •

Series resistance (Rs) •

Characteristic  resistance of solar cell (Rch) •

Photoreponse (RR)
