Samenvatting:
The Dye-sensitized nanocrystaline TiO2 solar cell (nc-DSC) developed byGraetzel has the potential to reach low costs in future outdoor power
applications. In addition, due to its expected ease of production and
possibilities to adjust its appearance, the potential for application is very
broad. When plastic foil is used as a substrate for the nc-DSC the production
and application possibilities are even bigger. Polymer foils are easier to
handle in processing steps such as cutting of larger entities into smaller
individual modules. Moreover the processing of foil into complete flexible
solar cells could be realized by means of a continuous roll to roll process.
This implies that for the flexible nc-DSC a higher throughput in production
could be realized. Also special applications requiring a certain flexibility
of the solar cell, such as smart cards, come into play. In this paper the
differences in cell performance and -stability between glass based nc-DSCs
and polymer foil based nc-DSCs are studied. The ITO coating on the polymer
foil appears to be a critical factor with respect to the photoelectrode
stability. TiO2 sintered at low temperatures (150 deg C) does not influence
the cell stability in a negative way. 5 refs.
