We have characterised a dye-sensitised nanoporous nanocrystalline titania film used in prototype photoelectrochemical solar cell production. The film was sensitised with two types of ruthenium (II) based dyes for different times, between 0.5 and 24 hours. The penetration and coverage for each type of dye was studied using Confocal Laser Scanning Microscopy (CLSM). Varying laser powers were applied and fluorescence images from the film have been analysed. Both dyes were found to percolate through the whole of the nanoporous film irrespective of the dyeing time but the amount of dye increased with dyeing time. The CLSM is shown to be a valuable tool for the investigation of dye penetration and coverage in porous films.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
