on the surface of the metal nanoparticle as a dispersant the desired coating system may be accompanied by a suitable solvent system in order to form the stable colloidal stable ink formation the solvents and stabilizer suitable to be used for the ink preparation includes acetone ethanol isopropanol diethyl glycol butyl ether ethyl acetate pentyl acetate ethylene glycol n butanol 1 methoxy 2 propanol tetrahydrofuran tetrahydrofurfuryl alcohol isopropyl alcohol octadecene 2 methyltetrahydrofuran n n diethylhydroxylamine 2 butoxyethyl acetate dodecane toluene water 1 2 propyl glycol polyvinyl pyrrolidone and benzyl alcohol four inks with various formulation were prepared using the plasma process synthesized ni x si y nanoparticles fig5 shows the corresponding viscosity measurements collected for the ink formulations the viscosity varied by changing the formation parameters i e metal loading solvents and organic coating used fig6 shows a typical ink jet printing of the nisi ink formulation a the ink jet printed track was about 230 u03bcm width on silicon wafer one method of forming the contacts between the fine particles of nickel and silicon for instance nickel silicide particles and the silicon surface is through oxidation of the anti reflective coating on a solar cell with a metal oxide diffusion enhancer the oxidation then allows the nickel silicide particles to pass through the anti reflective coating and form a contact with the silicon surface the gibbs free energy of the reaction between si 3 n 4 a major component of most anti reflective coatings and two different nickel and silicon containing particles ni 2 si and nisi were measured as shown in fig7 as can be seen the reactions are not.
