• : bundle diameter; sheet resistance; SWCNT; thin film; transmittance; Introduction Single-walled carbon nanotubes (SWCNT) offer great application potential in future electronics, such as micro-electromechanical devices [1], sensors [2][3], transparent electrodes [4][5][6], thin-film field-effect

• ]. Since the network resistance scales linearly with the number of contacts, conductance thus scales linearly with the average bundle length. The absorbance (A) and conductance (σDC) can be linked by the so-called figure of merit K [6] where Rs is the sheet resistance and T(λ) (later simply T) the

• transmittance measured at the middle of the visible spectrum (λ = 550 nm, or 2.3 eV). The UV–vis–NIR absorption spectra and four-point sheet resistance values shown in Table 1 were used to calculate the corresponding K’s shown in Figure 6. The solid curves represent previously published data for SWCNTs

• density, the substrate looks almost black and is therefore no longer transparent. In addition, the sheet resistance of the ITO layer increased to 40 Ω/sq (almost three times higher than that for pristine ITO). When heated in air at 550 °C, the polycrystalline ITO layer is known to degrade, leading to the

• biggest hindrances that affected the PCE of polymer cells made from similarly treated electrodes, because in our case (i) the sheet resistance of the electrode undergoes a limited increase during the low temperature CVD; (ii) the light transmittance of the ITO–glass does not reduce much, thanks to the low

• %). The lower PCE observed in the case of the large-area DSSCs compared to the small-area DSSCs is mainly attributed to the increase in the sheet resistance of the conducting FTO substrates resulting in an overall increase in the series resistance (Rs) of the large area DSSCs, which plays an important

• ZnO/Au-nanocomposite systems irrespective of the presence of the Schottky barrier. In the case of the large area ZnO/Au DSSCs, efficiency dropped to 3.27% and 1.16% for active areas equal to 0.25 cm2 and 1 cm2, respectively, which was mainly attributed to the increased sheet resistance of the FTO
