Abstract

Nanostructured dye solar cell (DSC) "mini-module", size 6 cm x 6 cm with similar to 15 cm(2) active area directly integrated on a stainless steel (StS)sheet has been demonstrated. With a configuration where the StS works as the photoelectrode (PE) substrate and the counter electrode (CE) is prepared on conducting glass or ITO-PET plastic foil, 3.4% and 2.5% total power conversion efficiencies, respectively, have been gained. Compared to results obtained with small, 1.6 cm x 2 cm cells with 0.32 cm(2) active area prepared with the same methods and materials, i.e. 3.4% efficiency with a StS PE and an ITO-PET CE, the large cell performance is not far behind. These efficiencies are also amongst the highest reported in the literature for this kind of a DSC configuration. Flexible structure enables high throughput roll to roll type industrial manufacturing of the cells and cost-efficient substrate materials make production of even modest efficiency cells economically feasible.
