Perovskite-based and OPV cells are said to represent a promising pathway to renewable energy generation due to their potential for lightweight, flexible, and potentially cost-effective solar power generation.
Elecolit 3648 is claimed to address one of the critical challenges in the commercialisation and long-term reliability of organic solar cells: creating flexible electrical connections that create and maintain reliable electrical circuits.
Electronic components are typically 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.
According to Panacol, this is why Elecolit 3648 is a significant introduction. It is a flexible, conductive adhesive. As it adheres well to plastics, including PI, PC, PVC, ABS, and FR4, Elecolit 3648 is suitable for an efficient attachment of wire leads 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, Elecolit 3648 can be hardened within seconds as a “snap cure” adhesive. As a one-component system, Elecolit 3648 simplifies manufacturing processes by eliminating the need for mixing and, therefore, ensures a consistent application. It can be dispensed 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 lead the generated electricity from the conductive tracks to the end device. This adhesive is also effective in touch sensors or wearable devices where flexibility is a desired property.
These features make Elecolit 3648 ideal for replacing solder joints in applications subjected to vibration, oscillation, or rapid temperature changes. This can include all configurations of flexible electronics, and specifically OPV. As the adhesive maintains its integrity after repeated bending and stretching, Elecolit 3648 can help to facilitate the development of new devices that withstand challenging operating conditions without losing performance.
