Camp, Jason, Gibson, Elizabeth A., Black, Fiona A, Wood, Christopher J., Ngwerume, Simbarashe, Summers, Gareth H., Clark, Ian P and Towrie, Michael (2017) Charge-transfer dynamics at the dye-semiconductor interface of photocathodes for solar energy applications. Faraday Discussions. ISSN 1359-6640

This article describes a comparison between the photophysical properties of two charge-transfer dyes adsorbed onto NiO via two different binding moieties. Transient spectroscopy measurements suggest that the structure of the anchoring group affects both the rate of charge recombination between the dye and NiO surface and the rate of dye regeneration by an iodide/triiodide redox couple. This is consistent with the performance of the dyes in p-type dye sensitised solar cells. A key finding was that the recombination rate differed in presence of the redox couple. This has important implications on the study of electron transfer at dye|semiconductor interfaces for solar energy applications.
