Abstract:
A new concept for the dye-sensitized nanocrystalline titanium dioxidesolar cell (nc-DSC) is introduced. The innovation involves the substrate
which is a polymer foil instead of glass. This innovation can be a
breakthrough in the processing of the nc-DSC's on an industrial scale,
because polymer foils are more easy to handle in processing steps as cutting
of larger entities into smaller individual modules. Moreover, the processing
of foil into flexible solar cells can be realized by means of a continuous
roll to roll process, whereas for the glass analogue batch processes are the
general rule. This implies that for the flexible nc-DSC a higher throughput
can be realized. Also, special applications requiring some flexibility of the
solar cell, such as smart cards, come into play. In this paper the efficiency
and stability of the nc-DSC's on polymer foil is considered in comparison to
the analoga on glass. 5 refs.
