1. A method of manufacturing a solar cell paste, the method comprising:
providing an electrically conductive material having a first viscosity, the electrically conductive material comprising one of Ag, Pd, Au, Pt, Ni, Cu, and Ru;
forcing the electrically conductive material through an orifice of a hydrodynamic cavitation chamber; and
subjecting the electrically conductive material in the hydrodynamic cavitation chamber to a hydrodynamic cavitation process by passing the electrically conductive material sequentially through a first primary orifice, a secondary orifice, and a final orifice within the hydrodynamic cavitation chamber to make a composition having a second viscosity.
