Abstract:
The working principle of a nano-crystalline dye sensitized solar cell(nc-DSC) of the Graetzel type depends on a working cycle consisting of dye
excitation, electron injection into titanium dioxide and fast reduction of
the oxidized dye by a redox couple. Continuous stability testing at Solaronix
on glass/glass thermoplastic sealed nc-DSC devices, revealed that no
significant degradation of the cell working cycle occurred over a period of
10,000 hours of illumination. New design concepts of low and high power
applications, introduced conform with market requirements, have resulted in
the world's first working nc-DSC plastic cell. A new sealing and
interconnection technique is introduced which is suitable for nc-DSC high
power applications. 4 figs., 4 refs.
