LED-based analysis of multijunction solar cells
LED's MEASURE TANDEMS Tandem Cells Demand High Accuracy For tandem cells, I-V measurements that lack careful tuning of the spectrum or stabilization, result in significantly distorted I-V curves, short-circuit current (Isc), and fill factor (FF), which are not representative of real-world conditions. NREL’s survey of tandem cell measurement methodologies found that only a fifth of the published [...]
