Conductive Adhesives

Electrically conductive adhesives from SoltaBond are a highly reliable connection method proven in such critical applications as satellites and pacemakers. Our conductive adhesives are engineered from well-proven epoxy technologies filled with silver particles, ensuring a very stable mechanical bond with excellent electrical conductivity. They can be applied at considerably lower temperatures than soldering. This makes them especially suitable for bonding flat wire connectors to thin film PV substrates (semiconductor, metal or TCO layer on glass, metal or plastic sheet), and as an interconnection method for new generations of thin and fragile crystalline Si cells using more sensitive semiconductor layers.

Our engineering group has many years of experience in the design and application of electrically conductive adhesives. We specially adapt our adhesives to each customer’s application to achieve low resistivity and stable bonds between the metal bus bar ribbon and the cell surface. For each adhesive solution, we provide support to select the best suited ribbon surface. We supply our adhesives either as one or two component versions in machine-ready cartridges or drums of different sizes. .

We understand the importance of making material handling in production as easy and stable as possible, and have therefore optimized our innovative adhesives for precision high volume dispensing equipment. In particular, our extensive application know-how makes us an excellent partner for companies who are setting up automated processes for the most cost effective manufacturing. Our production specialists in the field assure continuous improvements of our products and services.

We work in close cooperation with many material suppliers, ribbon manufacturers, equipment suppliers and research institutes. Before releasing any of our adhesives, we test them on substrates supplied by our customer. In our state-of-the-art laboratory we can do damp heat, thermal shock, UV and other tests following the IEC and UL module testing guidelines. We usually greatly exceed these test conditions during our internal tests, as we understand the importance of long-term reliability in PV modules and the harsh conditions to which they are subjected. We are confident of finding an optimized solution also for your application and focus strongly on close collaboration.
