The batteries are printed using a silk screen printing process in which a rubber lip presses the organic semiconductor materials through a screen onto a flexible substrate. The lithographic-like technique uses templates to pattern layer upon layer–each about the width of a human hair–of battery components until enough bulk has been achieved for a particular application.
