(close to 80%) comparable to ITO, and a much better conductivity than pure PEDOT:PSS film (48 ohm/sq). The
transmittance spectra indicate that the transmittance of the PEDOT:PSS/Ag grid hybrid film is lower than the case of
pure PEDOT:PSS film, this is due to the shadowing losses of the Ag grids. With a line-to-line distance of 1 mm, the Ag
grids cover about 16.4% of the total area. The transmitance can be increased by increasing the line-to-line distance. On
the other hand, the conductivity can be further increased by using higher conductivity PEDOT:PSS (PH 1000) and
optimizing the annealing process for the inkjet-printed Ag lines.
