Our outdoor test lab enables comparative performance and stability studies across the full scale spectrum — from lab-scale solar cells (<1 cm²) to industrial full-size PV modules. The outdoor lab was established in 2016. Focus areas: Performance, long-term stability and reliability testing of different solar-cell materials, especially perovskite based solar cells (single- and multi-junction) and modules. Solar cell monitoring: - MPP tracking and in-situ IV-curve measurements - Flexible orientation: Optimal (35°, South), BIPV / façade (90°), Agrivoltaics (90°, East/West with bifacial cells). Environment monitoring: - Irradiance, using pyranometers and reference Si sensors (plane-of-array, global and diffuse/direct irradiance) - Spectral irradiance (plane-of-array) - Device under test and ambient temperature - Relative humidity, air pressure and wind speed Data access: Publications + shared upon request.
