Photovoltaic Cells Evolve with Pressure-Sensitive Adhesives
Today’s Energy Solutions, July 2010.

As photovoltaic (PV) cell technology rapidly evolves from amorphous and crystalline silicon forms to thin film technologies, PV manufacturers are confronted with a new array of bonding and manufacturing process challenges. While liquid epoxies, ethylene-vinyl acetate (EVA) hot-melt adhesives, soldering, and mechanical fasteners have long been accepted bonding methods in the assembly of photovoltaic (PV) cells, pressure-sensitive adhesives (PSAs) are emerging as a viable option.

This article discusses how PSAs can be customized as sophisticated polymer formulations that deliver reliable bonds with added functionality to enhance the capabilities of a customer’s end product, while streamlining manufacturing processes.
