Concentrated nanoparticle and sol-gel inks have been created for the direct-write assembly of functional metallic and metal oxide materials. Direct-write assembly is an innovative, low-cost patterning technique in which specialized inks are printed in arbitrary planar and three-dimensional (3D) forms with lateral dimensions that are an order of magnitude lower than those achieved by inkjet printing. Paramount to this approach is the design of concentrated inks that can be extruded through fine deposition nozzles as filament(s), which then undergo rapid solidification in air to maintain their shape even as they span unsupported gaps or are patterned out-of-plane.1 9 (c) shows that the silver microelectrodes span the unsupported regions between each solar microcell without deformation. ... For a single microcell, an open circuit voltage, Voc, and short circuit current, Isc, of 0.41 V and 9 uA are measured, respectively. ... Figure 2.20 (e) displays the LED array, emitting uniform red light under an applied bias of 6 V from a single pixel, after annealing at 200AdC for 3 h.
