The SINUS-1000 ADVANCED mini-module tester paves the way for scalable perovskite PV technology
Leipzig, Germany, May 6, 2025 – WAVELABS, the award-winning German developer and manufacturer of LED-based solar metrology systems, is expanding its product portfolio with the launch of the new mini-module tester SINUS-1000 ADVANCED. This solar simulator goes beyond traditional photovoltaic research—it is a dedicated solution for R&D departments at module manufacturers seeking to scale up not only wafer-based, but also thin-film technologies, especially perovskites. The SINUS-1000 ADVANCED will debut at Intersolar Europe in Munich from May 7–9, 2025. At [...]
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 results are valid. LED’s up the game with reliable tandem measurements! Poor [...]
