Contribution of the solar effect in LEDs and spectral responses

Abstract

This experimental work describes our work on spectrometric measurements (spectral responses) and measurement of sensitivity of solar radiation by (simulating the solar to a powered lamp) on commercial light emitting diodes of different colors (LEDs). The first experiment was carried out at the electronics department in University of USTHB Bab Ezzouar (Laboratory of thin layers) which has a measurement bench allowing the relative spectral representation of the photo of the detector noted Vphot (λ).
