Surface engineering of solid-state dye-sensitized solar cells

The way that molecules interact with interfaces play a key role in the manufacture and performance of solid-state dye-sensitized solar cells (ssDSC). In order to maximise the performance of ssDSC, it is important to understand the interactions and to subsequently optimise them. The key interactions within the process, are the wetting and subsequent dyeing of the TiO2 layer by immersion dyeing, ultra-fast pump dyeing or spin coating. During the device making process, the dyes will arrange themselves in the configuration that results from lowest energy orientation, even if this is less favourable in terms of device performance,1, 2, 3. This poster describes our current work on the effect of TiO2 thickness on dye loading and device performance.
