Abstract EN
In this research, AuNPs prepared by laser ablation in liquid (PLAL) at 750 mJ energy and 90 pulses.
They have been added to N719-dye to form (Au-N719) mixture.
TiO2 paste was deposited on FTO substrates and immersion in a mixture dye and AuNPs.
DSSC was fabricated and enhancement of the DSSC conversion efficiency was achieved.
Scanning electron microscope, Xray diffraction and UV-Visible spectrophotometer were used to characterize and study the DSSC components.
The UV-Vis data show high absorbance of AuNPs+N719 dye compared to N719 dye only; that means the immersion of AuNPs in the N719-dye solution tend to increase the total absorbance of the dye.
The XRD pattern of AuNPs has diffraction peaks at 38.2° and 44.4° which can be indexed by (111), (200) plane of Au in the cubic phase.
The shape and size distribution shows spherical AuNPs with particle size about (50-60) nm.
The relative increase of short circuit current density after the adding gold nanoparticles was about 76%.
In the same way the relative increase of open circuit voltage after adding gold nanoparticles was about 6.7%.
The total photonto- current energy conversion efficiency for the standard DSSC is 1.75 while its 2.8 of the enhanced DSSC with gold NPs.The maximum enhancement is about 60 % under illumination (105 mW/cm2, (AM1.5).
