Silver nanoplates as inkjet ink particles for metallization at a low baking temperature of 100°C

Preparation of inkjet-printed titanium monoxide as p-type absorber layer for photovoltaic purposes

“…Printing work was carried out on Epson Stylus Photo T50 Printer which is mentioned in several research works by Lee et al [31,36,37]. The chosen printer with the piezoelectric print head, using DOD technology, has been characterized by outstanding technical features in addition to its low cost [30].…”

Annealed graphene sheets decorated with silver nanoparticles for inkjet printing

“…The residual oxygen-containing functional groups anchored to the rGO basal plane after reduction could be removed at large extent along with the restoration of the p-conjugated structure, increasing the conductivity of rGO nanosheets [27,28]. Additionally, pure nano-size metal ink such as silver and gold also provides an alternative to conventional carbon-based ink [29][30][31]. Although the inherently very low resistivity makes itself feasible for inkjet printed flexible electronics, the cost efficiency and metal migration problems still quest for further exploration [25,32].…”

The effects of nanoparticle shape on electrical conductivity of Ag nanomaterials

“…Compared with Ag spherical nanoparticles, the contact area among Ag nanocubes was larger than that between nanospheres, which resulted in more grain boundaries. It was also recently reported that the grain boundaries admist nanoparticles strongly dominate the electric conductance [12]. However, there are very few studies to demonstrate the effects of nanoparticles shape on electrical conductivity.…”

“…Among these factors, the morphology of nanoparticles has been found to have a significant effect on electrical resistivity of silver paste [12], because metallic nanomaterials with different shapes, including cubes, wires, spheres, triangles, and rods, are possessed of distinct crystal face. For instance, the crystalline structure of Ag nanocubes was determined to be face-centered cubic, principally consisting of (200) lattice planes [13], and Ag nanowires are mainly composed of (100) surface facet, while spherical Ag nanoparticles are dominated by (111) [14].…”

“…Conductive patterns using Ag nanoplate and nanoparticle ink were fabricated by inkjet printing, and the resistivity of the lines were determined [10]. Bulk resistivity of isotropic conductive adhesives (ICA) filled with Ag nanowires was compared with that of ICA containing micrometer-sized Ag particles and nanometersized Ag particles [10,12]. However, the appearance of Ag nanomaterials used in these studies was inhomogeneous, and the sizes of them were un-uniform [18], from the results of which we can not conclude that the discrepancy of the electrical conductance of these nanomaterials was ascribed to diversified shapes.…”
