In this paper Prof. Ulrich W. Paetzold's team at KIT achieved a record 24.4% efficiency in triple junction perovskite solar cells using a new vacuum-assisted growth process. The mid-subcell, made of FAPbI3, ensures thermal stability and ideal interfaces.
How Paios was used
The researchers used the PAIOS system for various measurements including electrical impedance spectroscopy, transient photovoltage, electroluminescence, photoluminescence imaging, Mott-Schottky, dark J–V curves, and space-charge-limited current, enabling efficient, streamlined analysis and characterization of their triple-junction perovskite solar cells .
