Head Ivanova Vita V., Кандидат технічних наук Registration Date 24-03-2026 Organization National Technscal University of Ukraine "Kiev Polytechnic Institute". popup.description1 To investigate the ideality factor of the voltage-current characteristics of LEDs and its correlation with noise characteristics and energy efficiency popup.description2 Non-destructive LED characterisation methods should be a reliable way to analyse the quality of crystals and LED assemblies in order to reduce the number of failures, increase the lifetime, reliability and energy saving. The experimental study of the electrical and optical characteristics of LEDs, which includes the measurement of the volt-ampere characteristic, luminous radiation power, spectrum, calculation of the ideality factor and the dependence of the corresponding values on the current, allows such characterisation to be carried out by detecting anomalies and determining their sources and probable causes. The abnormal ideality factor of the voltage-current curves is a reliable marker of current leakage channels, in particular, due to the presence of defects in the active area.
