Fabrication and Efficiency Enhancement of Z907 Dye Sensitized Solar Cell Using Gold Nanoparticles

Dye-Sensitized Solar Cells: Fundamentals and Current Status

“… By promoting the use of different materials in the manufacture of electrodes like nanotubes, nanowires of carbon, graphene; using varied electrolytes instead of a liquid one like gel electrolyte and quasi-solid electrolytes; providing different pre-post treatments to the working electrode like anodization pre-treatment and TiCl 4 treatment; using different types of CEs [ 14 ] and by developing hydrophobic sensitizers, the performance as well as the efficiency of these cells can be tremendously improved. By inserting phosphorescence or luminescent chromophores, such as applying rare-earth doped oxides into the DSSC [ 58 – 60 ], coating a luminescent layer on the glass of the photoanode [ 60 – 62 ], i.e., using plasmonic phenomenon [ 63 ] and adding energy relay dyes (ERDs) to the electrolyte [ 57 , 64 , 65 ]. …”

“…The PCE of the device was improved from 2.83 to 3.62% with increment around 28% after incorporation of the 2 wt% of the Ag NPs due to the plasmonic effect of the modified electrode. Bakr et al have fabricated Z907 dye-sensitized solar cell using gold nanoparticles prepared by pulsed Nd:YAG laser ablation in ethanol at wavelength of 1064 nm [ 63 ]. The addition of synthesized Au NPs to the Z907 dye increased the absorption of the Z907 dye, thus achieving ɳ = 1.284% for the cell without Au NPs and 2.357% for the cell incorporating the Au NPs.…”

Current Status of Emerging PV Technologies: A Comparative Study of Dye-Sensitized, Organic, and Perovskite Solar Cells

“…Jun et al [57] incorporated Au nanoparticles into the commercial TiO 2 nanopowder that was used to create the photoanode and achieved an increase in efficiency by approximately 50% compared to devices that did not contain Au nanoparticles. Bakr et al incorporated Au nanoparticles prepared by pulsed Nd:YAG laser ablation at 1064 nm in a solution of Z907 dye [58]. The addition of the synthesized gold nanoparticles to the dye resulted in an increase in device efficiency from 1.284% to 2.357%, due to increased light absorption from the gold nanoparticles.…”

Model systems for dye-sensitized solar cells: cyanidin-silver nanocluster hybrids at TiO2 support

“…30 This opens a route for enhancing the optical properties as well as improving the light-harvesting efficiency of natural dyes through interaction with silver NCs which introduces donor-acceptor subunits. Previous work has demonstrated that ligated noble metal NCs 31,32 as well as noble metal nanoparticles (NPs) 33,34 can contribute towards more efficient sensitizers.…”
