Abstract:

The 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 ZnTiO4 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 ZnTiO3 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 ZnTiO3 (101) and (110) surfaces. The electronic structures and photoelectrical properties of cyanoacrylic at ZnTiO3 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.
