\n Photovoltaics<\/span>\n and OPV<\/span>\n <\/h1>[\/vc_column][vc_column width=”1\/2″][vc_column_text css=””]Organic photovoltaics (OPV) are creating radically new applications in consumer electronics.\u00a0They include indoor light harvesting to extend battery life of wearables, and outdoor energy generation with performance previously unimaginable from conventional photovoltaics. The same is true for flexible electronics. Manufacturers are redefining the boundaries of volumetric form factor, functionality, and design flexibility in consumer and automotive electronics.[\/vc_column_text]\n

In all cases, the specific requirements of the application and its assembly process are key factors to consider when making an adhesive selection. Significant benefits can be realized when an optimal pairing is achieved with the component design, assembly, (UV) adhesive properties, and the curing process.\u00a0Component and process design is afforded much greater flexibility.\u00a0 High throughput processes, including reel-to-reel, can be run with greater efficiency which reduces total cost of operation. Finished products can also possess more functionality and durability.<\/p>\n

As new designs are evolving rapidly, very little standardization exists in the manufacturing of OPV. To support this evolution, adhesives must be modified or developed to meet the customers\u2019 unique OPV design, materials, and processes.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”18334″ img_size=”full” css=””][vc_column_text css=””]An electrically conductive adhesive is dispensed into laser-cut holes for the electrical connection of flexible solar films.[\/vc_column_text][vc_column_text css=””]Download:<\/p>\n
