Abstract

While the global market for photovoltaic (PV) modules continues to grow 30% - 40% annually, manufacturers are looking at advanced technologies and cell concepts in order to improve the cost performance and reliability. One of the challenges faced by the silicon (Si) PV manufacturers is the lack of efficient metal screen-printing technologies. While screen-printing is a long-established technology, THE traditional silver-based pastes have technical limits in terms of paste composition, drying and thermal-firing conditions, line-width, aspect ratio, contact resistance, etc. Such limits keep the industrial cell structure from being close to an ideal PV cell architecture. In an effort to develop alternate printable pastes electrically, electrically conductive adhesives are considered in this study to provide fine-line contacts and low thermal budget so that performance-driven solar cell designs can be reliably implemented in manufacturing. Mechanical properties of solar cell printed by conductive adhesives are experimentally investigated in this work and confirmed with the simulation results.
