Blackburn, Octavia A., Coe, Benjamin J., Hahn, Valentine, Helliwell, Madeleine, Raftery, James, Ta, Yien T., Peter, Laurence M., Wang, Hongxia, Anta, Juan A., & Guillén, Elena (2012) N-Aryl stilbazolium dyes as sensitizers for solar cells. Dyes and Pigments, 92(1), pp. 766-777.
Given the urgent need to develop clean and renewable energy sources, there is much current interest in using molecular dyes, especially transition metal complexes, as sensitizers in solar energy harvesting . Traditional solar cells rely on the direct absorption of photons by a semiconductor, but their efficiency is limited because visible light absorption requires narrow band-gap semiconductors which are inherently unstable with respect to photodegradation. In a major breakthrough in 1991, O’Regan and Grätzel reported efficient photosensitization of a wide band-gap semiconductor by a trinuclear RuII-2,2-bipyridyl-based dye . The chromophoric properties of such complexes derive from intense, low energy metal-to-ligand charge-transfer transitions.
Citation countsare sourced monthly fromand 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.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
