abstract={Future solar cells need to be cheaper, more efficient and produced in an environmental
friendly way to be a competitive and sustainable alternative for solar energy conversion.
The emerging dye sensitized solar cells (DSSCs) might be able to meet future demands
regarding price, structural flexibility and environmental issues, but for the time being,
their potential as a competitive and viable alternative is hampered by low energy conversion
efficiencies and stability issues. A most central process in the conversion of
sunlight energy directly into electric energy, is the photon to charge carrier conversion
which takes place in the photoactive part of the solarcell. To achieve a high incident photon
to charge carrier efficiency (IPCE), efficient absorption of incoming sunlight over a
wide range of wavelenghts is needed. The use of plasmonic effects generated by metal
nanoparticles (MNP) in combination with a sensitizing dye is an interesting approach
to increase the IPCE for DSSCs. In this work, effects on cell energy conversion efficiency
of adding gold nanoparticles (GNPs) have been studied. Spherical GNPs of diameter 5,
10 and 40 nm, embedded in the photoactive layers have been studied in combination
with three different sensitizing dyes; Ruthenizer 455-PF6, Ruthenizer 620-1H3BTA and
Sensidizer SQ2. Cells without dye were also included in the study. TiO2 was used as
semiconductor material in thin(< 1μm ) photoactive layers. Complete DSSCs containing
gel electrolyte have been built and characterized with I-V graphs using different
light intensities of 0.11, 0.55, 0.79 and 1.0 sun.
The results clearly show that the cell efficiency can be improved by using GNPs this
way, it was also shown that certain combinations of dye and GNP sizes affected cell efficiency
more positive than others while addition of GNPs to cells without dye sensitizer
affected the efficiency negatively. Most positive results were achieved using the organic
dye Ruthenizer 455-PF6 in combination with 40 nm GNPs, showing relative efficiency
increase well above 25 %.},
