Summary on Grant Application Form
Dye sensitised photovoltaic devices typically employ a liquid electrolyte to allow electrical contact to the internal surface area of mesoporous ceramic film. Problems associated with the sealing of such liquids are motivating studies of alternative, solid state, electrically conducting materials. However studies of such solid state dye sensitised (SSDS) solar cells have had only limited success to date. Graetzel and co-workers have reported an 0.8% efficient device using a molecular hole conductor. We have recently developed and patented a solid state solar cell employing an ionic polymer with 1.5% efficiency at 1/10th sun illumination; commercial development of this approach has recently been initiated in collaboration with Johnson Matthey plc. However scientific study of the function of SSDC solar cells have been very limited to date, with materials design being largely empirical. In this project we propose a systematic study of the function of such devices, building upon our established expertise in the characterisation and modelling of porous, dye sensitised heterojunction devices, with the aim of developing a rigorous scientific basis for the long term development of efficient solid state, dye sensitised photovoltaic cells.EngProg\
