EL imaging is experimentally quite simple. Unfortunately in general a quantitative evaluation of the diode quality is not possible, but is limited to very low quality devices. Conversely, PL imaging is experimentally more challenging but allows also a quantitative evaluation of the diode quality for state-of-the-art devices. Experimentally the two techniques are compared analyzing two differently processed solar cells made of multi crystalline sister wavers.enPV Produktionstechnologie und QualitätssicherungSilicium-PhotovoltaikCharakterisierung von Prozess- und Silicium-MaterialienMesstechnik und ProduktionskontrolleProduktionsanlagen und ProzessentwicklungCharakterisierungZellen und Module621697conference paper
