摘要:The dye-sensitized nano solar cell (DSSC) is one
of the photochemical electric cells, which consists
of the photoelectrode, the dye, the electrolyte,
and the counter electrode. The most speciality
of the DSSC relative to the other types of solar
cells is the use of the dye. It’s well known that
the energy gap size of the applied semiconductors
determines the absorption frequency of light in the
solar cells. A significant purpose for using the dyes
in the DSSC is to expand the absorption spectra
on the visible light due to the visible light owns
ca. 96% energy of the sun light. The absorption
spectra of the DSSC is decided by the combination
of the photoelectrode’s nanoparticles, e.g. TiO2,
and the dyes, where the dyes can help the DSSC
to expand their absorption spectra. This article
presents some experimental data for analyzing the
various dye’s absorption spetra, which can be appied
in the DSSC. The analyses of dyes are focused on
the natural dyes which are extracted by the plants
and compared with the chemical synthesis as well
as the TiO2 nanoparticles. The results show that
the natural dyes have the wider absorption spetra
than the chemical synthesis due to the more various
constituents in the natural dyes.
