 This paper proposes a self-induced electric field-driven jet printing method for fabricating ultrafine silver grids using only a copper foil as an extraction electrode, which reduces fabrication cost and residual charges for improved printing stability. Silver grids with line widths ranging from 300 Nm to 7m and aspect ratios of 0.39 to 1 have been successfully printed using optimized parameters and high viscosity silver paste, resulting in excellent transmittance, T equals 92 percent, and sheet resistance, RS equals 1.3429 omega square 1.
