This paper describes an experimental work on the electrical characterization of commercial LED of different colors and their photoelectric effect. A research work has been carried out to develop the experimental measurement in order to show the presence of a photovoltaic effect on LEDs. For this purpose, we measured the electrical characteristics of individual LED and studied their light intensities using a pyranometer EPLEY. This work focused mainly on red, green and yellowLEDs. Moreover, we have implemented an experimental system for the measurement of sensitivity of different LEDs depending on the power of light from a light source. A comparison was made between theoretical model and experimental results.
