ITO as a transparent electrode is required not only to have a low sheet resistance and also the smooth surface. The low sheet resistance can reduce the heat generating from the current path through. The sheet resistivity is normally expressed as ohms/square or Ω/ . The resistance of a square conductive sheet is the same no matter what size it is so long as it remains a square. For non-uniformly doped n-type layers, ie., if ρ is non-uniform: The sheet resistivity of an emitter layer is typically measured with a four-point-probe.

The utility of sheet resistance as opposed to resistance or resistivity is that it is directly measured using a four-terminal sensing measurement (also known as a four-point probe measurement) or indirectly by using a non-contact eddy current based testing device. Sheet resistance is invariable under scaling of the film contact and therefore can be used to compare the electrical properties of devices that are significantly different in size.

EE 432/532 Resistance – 6 Sheet resistance Look again at the resistance equation with uniform resistivity. R = ⇢ t · g The quantity ρ/t has units of resistance. We note that it is a property of the particular layer (doping and thickness). This quantity is important enough that we give it a new name: the sheet resistance. The units Sheet resistance is defined as ρ/t: the resistivity (Ω*m) divided by the thickness (m) of the conductive ITO coating. The units are given as Ω/sq (Ohms per square) to differentiate the sheet resistance from the total resistance of some area of the film. Academia.edu is a platform for academics to share research papers. The sheet resistance of ITO coated films on PET substrates is listed in Table 3.2. It is found that the thickness increases nearly linearly from 25 to 114.5 nm when the deposition time increases from 10 to 20 min. The sheet resistance of ITO film decreases with deposition time as the thickness of the film increases. This
