PV Module Characterisation and Reliability Group

The group operates SERIS’ ISO/IEC 17025 accredited laboratory for PV module testing. Its research activities focus on two main topics: (i) Electrical characterisation of PV modules and (ii) PV module reliability. High-efficiency PV modules and innovative architectures - such as bifacial, floating, curved, coloured and multi-junction modules - are the subject of research on new and innovative measurement methods for which standardisation is required. Reliability studies are conducted via investigating the theoretical basis and the kinetics of important PV module degradation mechanisms such as PID (potential-induced degradation) and LeTID (light and elevated temperature induced degradation). Studies of the module degradation modes in high-humidity and high-UV conditions are performed based on the data and evidence from the field. Reliability stress testing of modules designed for floating PV is a new research topic that is attracting attention from the PV industry. Furthermore, pre-normative PV module metrology activities are routinely conducted in liaison with the International Electrotechnical Commission (IEC) and research partners worldwide.
