Summary on Grant Application Form |

Novel photovoltaic devices based upon dye-sensitised nanocrystalline Ti02 films were first reported in 1991. They function by the injection of an electron from the optically excited dye molecule into the Ti02, ultimately leading to the production of electrical poser. Thses photoelectrochemical solar cells are already entering industrial production with the technology offering the potential for a 5-fold drop in production costs compared to conventional silicon PV cells. A key development of this technology is the identification of alternative sensitiser dyes, and in particular, dyes with an improved match with solar radiation. Only limited success in this direction has been achieved to date, due to the lack of scientific knowledge concerning the dye sensitisation process. The basis of this proposal is a systematic study of the sensitising properties of a promising class of sensitising dyes: substituted metallo-phthalocyanines. It aims to unravel the factors controlling efficient electron transfer from phthalocyanine sensitisers to Ti02. The work will:1. Involve both the development of strategies for the synthesis of sequences of axially- and peripherally-substituted phthalocyanines and 2. An investigation of their spectroscopy and electrochemical action in solutino and in photoelectorchemical solar cells, leading to the development of improved sensitiser dyes for commercial applications.
