SERIS operates a PV Module Development Laboratory where PV modules ranging from small single-cell modules for testing purposes up to full-size 72-cell modules can be fabricated. Services offered by the lab include:
- Processing of individual module components into full prototype modules for subsequent testing and qualification
- Detailed characterisation of PV module components (glass panes, encapsulants, ribbons, backsheets, etc)
- Partial processing of PV modules for process or component verification
- Quality and yield analysis of PV module components
- Identification of the root causes of PV module failure after certification tests
Selected research activities currently conducted in the PV Module Development Group include:
- Glass-glass bifacial modules - development of PV modules tailor-made for the tropical climate
- Indoor and outdoor studies of potential-induced-degradation (PID) of PV modules
- Development of cost-effective and production-ready high-performance PV modules using multi-busbar halved-cell technology
- Recycling and repair of PV modules
- Comprehensive cell-to-module (CTM) power loss analysis
