Abstract: This
research aims to
investigate the effect
of dye adsorption
into TiO2 layer
in dye sensitized solar
cell (DSSC), which
the TiO2 layer
is formed by
slip casting and electrophoresis methods. Adsorption
process of the dye into the cavities of the TiO2 layer was conducted by electrophoresis technique.
As results, two
DSSCs prepared by
the slip casting and
electrophoresis methods were
successfully realized and
tested. In case
of DSSC based on electrophoresis method, XRD results show the appearance
of MgO on TiO2 layer, which is
probably caused by
the addition of
salt Mg(NO3)2 in
the electrophoresis solution. Therefore,
electrophoresis condition without
the addition of
salt needs to be investigated
in the next research. It is found that the electrophoresis method can be used in
the process of dye adsorption into the TiO2 layer. The electrophoresis with
larger voltage results in the
larger DSSC output.
It is also
seen that open
circuit voltage for
the slip casting-based DSSC
is found to be greater
than that for
the electrophoresis-based one. This
may be due to
the larger size
of the pores
in TiO2 layer
for the slip casting
process compared to that for the electrophoresis process. For larger
size of the pores, the dye can easily fit into the pores with the help of
electrophoresis.
