The Cluster develops and characterises novel and advanced PV module technologies suited for urban and tropical applications. It consists of two research groups - the PV Module Characterisation and Reliability (PVMC&R) Group and the Building Integrated Photovoltaics (BIPV) Group. The Cluster is located in the CleanTech One (CTO) building at CleanTech Park, hosting the ISO/IEC 17025 accredited laboratory for PV module testing and the PV module technology R&D laboratory. The Cluster’s main R&D activities are: Development of building-integrated PV technologies (for SERIS’ BIPV flagship project) and for various urban solar applications; Advanced and pre-normative characterisation methods for PV modules; Reliability studies for the three flagship projects of SERIS (tandem solar cells, BIPV modules & systems, floating PV); Studies of degradation mechanisms that are particularly relevant in the tropical climate, including Potential Induced Degradation (PID); PV module recycling.
