NanoMas Technologies has developed a new family of ultrafine nanosilver-based conductive inks for the printed electronics and solar industries. During synthesis the particles are coated with a thin layer of organic surface ligand that allows the nanoparticles to be dispersed in the solvent phase subsequent to processing. Silver nanoparticle inks have also been developed for aerosol jet printing, in which an aerosol of the ink is created either by pneumatic or ultrasonic atomization. The company says that its observations indicate that the small size of the nanoMas nanoparticles significantly improves the settling behavior of formulated inkjet inks over competing materials. The ultrafine nanoparticles also enable the formulation of inks for non-contact printing of the front side metallization of crystalline solar cells, resulting in higher cell efficiencies than is possible with metallizations produced by more conventional printing techniques.
