T
he aggregation of sensitizers on a semiconductor is crucial
for determining the light-harvesting efficiency of dye
sensitized solar cells (DSSCs). The interfacial properties of dyes
adsorbed on a ZnTiO
4
film, such as adsorption configurations
and adsorption energy, can impact the total amount of dye
sensitizers that loads and the stability of a DSSC device.
In this work ZnTiO
3
perovskite was selected as a photoanode
for DSSC. First principal calculation study based on the DFT
method has been used to study the adsorption energy of
the Cyanoacrylic dye onto ZnTiO
3
(101) and (110) surfaces.
The electronic structures and photoelectrical properties of
cyanoacrylic at ZnTiO
3
complex are performed using the
generalized gradient approximation approach (GGA-PBE), in
order to treat the vend-wells interaction, DFT-D approach was
applied in CASTEP code
.
