The method of determining the edge emission output also varied between studies, for example, while most studies used an integrating sphere to collect emitted photons (see Experimental section), Zettl et al. used a fiber optic cable (20 μm diameter) placed at the center of one of the edges of the LSC. Since the photon output has been shown to fluctuate along the edge length, this approach may have artificially inflated the photon output in this study. Regardless, while finetuning the model with better input data could have improved results, pvTrace v2.1.sv shows strong agreement with previously reported experimental studies. and.
