• %). 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
