Abstract:
A fully operational baseline consisting of dedicated equipment to processnanocrystal-line dye-sensitized solar cell devices has been installed
at ECN. This baseline focuses on the production of glass/glass devices
with dimensions up to 10x10 cm2. Present power conversion efficiencies
of 6% obtained for cell areas of 2.5 cm2 are successfully translated
to 100 cm2 devices with an active area of 68 cm2 by application of identical
cell components. The power conversion efficiency with respect to total
area was 4%.
Processing of a large number of devices in the baseline shows good results
in terms of process reliability and yield. The overall yield for a series
of 27 devices (10x10 cm2)was 96%, while 84% (22 of the remaining 26
devices) generated a cell efficiency within 7% deviation from the average
value (4.3%). The reproducibility of the tita-nium
dioxide (TiO2 ) colloid synthesis has been investigated. The deviation
from the
average efficiency (4 9%) of three batches of colloid was at most 3
2%. These results prove that complete device manufacturing of nc-DSC
by a baseline process, starting with colloid synthesis is reproducible
for surfaces up to
10x10 cm2. Copyright 2003 John Wiley & Sons, Ltd.
