Panacol introduces new flexible conductive adhesive for OPV applications
Perovskite-based and organic photovoltaic (OPV) cells represent a promising route to renewable energy generation due to their potential for lightweight, flexible, and potentially cost-effective solar power generation. Panacol complements new OPV technologies with Elecolit 3648, a newly developed conductive adhesive.
Electronic components are usually connected by soldering. However, solder materials are rigid and inflexible, and soldering temperatures are often too high for potentially heat-sensitive photoactive materials. Conventional conductive adhesives cure at lower temperatures but can still be brittle and inflexible.
This is why Elecolit 3648 is a significant introduction. It is a very flexible, conductive adhesive. As it adheres well to plastics, including PI, PC, PVC, ABS, and FR4, it is the perfect choice for efficiently attaching wires and components to create flexible connections. Elecolit 3648 can be cured at relatively low temperatures of 80°C within a few minutes. At higher temperatures it can be hardened within seconds as a “snap cure” adhesive. As a one-component system, it simplifies manufacturing processes by eliminating the need for mixing and therefore ensures a consistent application. It is easy to process and can be applied by conventional dispensing equipment, by jetting or screen printing.
Elecolit 3648 can efficiently secure flexible resistors and create flexible electrical connections in solar cells to carry the generated electricity from the conductive tracks to the end device. It not only complements new OPV technologies, but is also effective in touch sensors or wearable devices where flexibility is a desired property. These features played a key role in selecting the newly introduced adhesive to replace solder joints in applications subjected to vibration, oscillation or rapid temperature changes. By maintaining its integrity after repeated bending and stretching, Elecolit 3648 can help facilitate the development of new devices that can withstand challenging operating conditions without compromising performance.
