Mattias Juhl speaks at UNSW SPREE


Mattias Juhl's PhD, the focus of this presentation, investigated the spectral response of photoluminescence. This technique involved monitoring both the sample's spectral lumped photoluminescence and the photon flux incident on the sample for different illumination wavelengths. This presentation outlines the spectral response of photoluminescence is able to provide information about a sample's electrical and optical properties, without the requirement for contact nor junction formation. It will be discussed how that the spectral response of photoluminescence can provide a contactless relative measurement of a samples: External Quantum Efficiency and band-to-band absorptance. The talk will also cover the topic of voltage independent carriers; carriers that remain in the device but do not contribute to the terminal voltage or short circuit current.
