Nanocrystalline dye-sentitised solar cells having maximum performance

Objective

The last years work on dye sensitised solar cells (DSC) has been restricted to the optimisation of cells with a standard photo electrode design, i.e. a single sensitising dye adsorbed on nano-crystalline titanium dioxide. Although great progress has been made in terms of stability, in large part due to work on electrolyte composition and sealing, no progress has been made in efficiency. The proposed project will drastically break with this practice. Recent announcements in literature call for imagination and exploration of new innovative ideas. New concepts, both for cell design and materials, are necessary to boost the efficiency from present 7-8% to 15% in the future. In particular, large numbers of test cells with thinner and multiple layer structures will be produced. Nano-crystalline oxides with reduced electron recombination properties will be prepared and surface selective as well as NIR-enhanced sensitising dyes will be applied. The project will provide the basis required for a breakthrough of the DSC technology in terms of costs per watt peak and long-term stability.
