Roll-to-roll organic coater

High-speed roll-to-roll printing allows the processing of many square meters of polymer electronics, in a semi-continuous manner. Production starts with a roll of flexible plastic foil onto which the device is built, layer by layer, using one of several printing or coating methods, and finally rolled up onto the coil again.

Ready-to-use units can then be cut and laminated from the roll. The whole process, from feedstock to finished product, is performed roll-to-roll, and this paves the way towards mass production and correspondingly low unit costs for devices such as organic solar cells.
