Presented at: 3rd World Conference on Photovoltaic Energy Conversion, Osaka, Japan, 11-18 mei 2003.
Abstract:
At ECN Solar Energy, the dye sensitised solar cell (nc-DSC) is developedfrom laboratory scale to the pre-pilot module stage. The process line
with mechanised equipment for 10×10 and 7.5×10 cm2 devices is presented.
Power conversion efficiencies of 6% obtained for cell-areas of 2.5 cm2
are successfully translated to 100 cm2 devices (active-area 68 cm2)
by application of identical cell components. Reproducible efficiencies
of 6.0±0.3% are achieved at high yields of over 85%. These results prove
that complete device manufacturing of nc-DSC using a baseline process,
starting with colloid synthesis is reproducible for surfaces up to 10×10
cm2. Four-cell 30×30 cm2 modules are constructed to verify the feasibility
of translating critical process steps carried out on 10×10 cm2 to 30×30
cm2. Cost calculations based on the present processing schemes
(semi-automated) indicate a cost level of 2.5 Euro/Wp at 1 MWp/year
capacity,
of which labour amounts to 40%.
