A one-component electrically conductive adhesive (ECA) for flexible perovskite and organic photovoltaic connections is now available from German adhesive developer Panacol. The adhesive can offer an alternative to solder joints in applications subjected to vibration, oscillation or rapid temperature changes.

Elecolit 3648 adheres effectively to diverse plastics, including polyimide, polycarbonate, polyvinyl chloride, acrylonitrile butadiene styrene and flame-retardant epoxy resin. The flexible and conductive adhesive beSource: Panacol cured at relatively low temperatures of 80° C within a few minutes. Elecolit 3648 can be hardened at higher temperatures within seconds as a “snap cure” adhesive.

The solvent-free, one-component ECA with silver filler simplifies manufacturing processes by eliminating the need for mixing and therefore ensures a consistent application. It is easy to process and can be dispensed by conventional dispensing equipment, by jetting or screen printing.

Elecolit 3648 is formulated to 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. The adhesive is also applicable to touch sensors or wearable devices where flexibility is a desired property.
