“…The capability of highly photoactive metal-treated Titanium dioxide nanoparticles will open up new opportunities in a variety of disciplines, including photoelectrochemical water splitting and a variety of other applications. [56] This cosensitized TiO 2 layer presented a considerable panchromatic photocurrent reaction over the visible range, obtaining IPCE up to 90 %. In addition, a co-sensitization approach was suggested by Lee to eliminate the Al 2 O 3 film.…”

The rapid depletion of fossil fuel soon would drive us to look for an alternative clean energy resources to meet the global energy demand. Several attempts have been made in recent years to improve the performances of renewable energy devices to achieve higher efficiency and to compete with conventional energy sources. Solar cells have great potential for a sustainable solution to the world energy crisis. The titania (TiO 2 ) is the most frequently used photoanode in dye-sensitized solar cells (DSSC) but its interfacial defects and restricted optical features lead it to low performance. The advent of Au/ TiO 2 nanocomposite materials as photoanode in DSSC has explored new approaches in the successful optimization of renewable energy devices. The newly invented plasmonic dyesensitized solar cells (PDSSC) also have optimized performance as well as reduced adverse effects. The fabrication of nanostructured composites with the inclusion of metallic nanoparticles is very helpful to increase the light scattering by plasmonic effects. The PDSSC facilitates the electronic transport by reducing the electron-hole recombination rates due to the surface plasmon resonance effect of gold nanoparticles anchored with titania that's why these types of cells achieved maximum attention in the current era. In this review, fundamentals, recent developments, and future perspectives of PDSSC have been discussed.

“…The addition of too large Ag increases the conductivity of a material, if it is associated with the energy gap, the conductor material has a small energy gap. This applies to several metals, one of which is Ag, when the conductivity of a material is higher, the conduction band and the valence band will overlap other so that it will affect the efficiency of a material [4,5].…”

“…The size of TiO2 nanoparticles is about 21 nm and has a fairly large and porous surface area, it is very possible for metal insertion to increase efficiency value [4]. One of the metals that has been used for the manufacture of DSSC is Au metal but because Au has a high commercial value, silver (Ag) is used in this study [5]. Ag metal is a noble metal group that has corrosion resistance properties and has high conductivity.…”

“…Ag metal is a noble metal group that has corrosion resistance properties and has high conductivity. In the previous research stated that Ag-doped TiO2 can increase the performance of DSSC, besides the addition of Ag dopant will inhibit the growth of the rutile phase in the TiO2 semiconductor material [5,11]. From the explanation above, DSSC fabrication has been carried out using LEG4 dye and spin coating method, with the addition of Ag concentration expected to improve DSSC performance.…”

DSSC (Dye-sensitized Solar Cell) has been the subject of much discussion by researchers because of its use and benefits for human life to get electrical energy from renewable sources. Many modifications were made in order to increase its efficiency. One of them is the addition of Ag at various concentrations of Dye LEG4 (D1;D2;D3;D-Ag). Dye LEG4 (triphenylamine) is one of the synthetic dyes synthesized from dyenamo orange (D35) dye and obtained 4 variations of dye, LEG4 is the result of the synthesis which has the highest efficiency. Ag metal was chosen because it has high conductivity properties. The DSSC compound composed of a working electrode (based on FTO glass coated by TiO2 and hybridized using dye LEG4+Ag) and a counter electrode based on FTO glass coated by platinum. DSSC devices arranged in a sandwich is tested for its optical properties by using a UV-VIS spectrophotometer to determine the absorbance curve of dye and to get Gap energy and IV-Meter to determine the efficiency.
