3.3.4 Low-Cost TCA Interconnected >4” Silicon-Based Tandem Cells
• Further develop novel interconnection using low-cost TCA bonding by adapting this bonding technology for different silicon bottom cells
• Develop optical design database for various combinations of top cells and silicon bottom cells, and demonstrate large area (>4”) processing capability.
• Investigate encapsulation and long-term stability through the collaboration with industry partners (Longi, Jinko).
• Evaluate life cycle performance, cost and commercialisation pathways.
