Dopant inks, methods of making dopant inks, and methods of using dopant inks
Printable dopant formulations, methods of making such dopant formulations, and methods of using such dopant formulations are disclosed. The dopant formulations provide a printable dopant ink with a viscosity sufficient to prevent ink spreading when deposited in a pattern on a substrate. Furthermore, an ion exchange purification process provides the dopant formulation with a reduced metal ion concentration, and thus a relatively high purity level. Consequently, the dopant residue remaining on the substrate after curing and/or dopant activation process is relatively uniform, and therefore can be easily removed.
