The PVM cluster develops and characterises novel and advanced PV module technologies suited for urban and tropical applications. It consists of two research groups - the Building Integrated Photovoltaics (BIPV) Group and the PV Module Characterisation and Reliability (PVMC&R) Group. The cluster is located in the CleanTech One (CTO) building at Singapore’s CleanTech Park, hosting the PV module technology R&D laboratory and SERIS’ ISO/IEC 17025 accredited laboratory for PV module testing. 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 for tropical climates, including potential induced degradation (PID); and novel methods for PV module recycling.
