Abstract
A requirement for success of the DSC technology on the market for building-integrated PV is visually attractive DSC panels holding a lifetime comparable to alternative facade materials and delivering electricity at reasonable prices. This project concerns the stability and durability of the DSC panel as these are decisive factors for the lifetime of the panels and the price of the produced electricity. The largest challenge of the DSC sealing is the high-performing well-documented - but also aggressive and volatile - iodine/triiodide electrolyte. The heat-sensitive Ru-dyes represent another challenge, as the dye should not be exposed to temperatures above approx. 100 deg. C during the sealing process. Despite the fact that less aggressive electrolytes and more stable dyes are highly focused R and D tasks, the work in the actual project has been carried out according to a 'worst case' strategy, i.e. the search has been for a sealing which is compatible with the iodine/triiodide electrolyte and the Ru-dyes. The rationale behind this strategy is the demanding lifetime requirement s for building-integrated products, which requires the ultimate sealing. In addition to the focus on the DSC sealing, work has been dedicated to the development of a more encapsulation-friendly electrolyte, in which

The ultimate result of the project is an improved polymer edge sealing for DSC cells. The sealant is - contrary to Surlyn and Bynel - stable in contact with the aggressive iodine/ triiodide electrolyte. The sealing is formed by lamination at elevated temperature and under controlled conditions. The robustness and capacity of the sealing process need to be further improved in order to fulfill the laboratories ambitions with regard to volume production of DSC cells and modules. Furthermore should the new sealing be compared both stability-wise and cost-wise with the lead-free solder glass solution, if such an edge sealing can be formed. (LN)}
