The advent of shingled passivated emitter rear cell (PERC) solar cell technology has spurred the development of innovative materials for interconnection, particularly in the form of electrically conductive adhesives (ECAs). This thesis investigates water-based ECAs formulated with silver microflakes, specifically tailored for shingled PERC solar cells. The research focuses on optimizing the electrical conductivity, adhesion properties, and reliability of these adhesives under solar cell operating conditions. The performance of these ECAs is evaluated and compared against commercial products through systematic experimental analysis and characterization. The outcomes provide valuable insights into the feasibility and effectiveness of water-based ECAs as an interconnection method in shingled PERC solar cell manufacturing. In this context, the volume resistivity of the water-based adhesive produced was measured to be 22 μOhm-cm at a film thickness of 25 μm. Cell characterizations showed a 0.4% increase in efficiency compared to commercial products. This study advances the understanding and application of environmentally friendly, cost-effective, and reliable interconnection solutions in photovoltaic technology.
