چکیده
Localized surface plasmon resonance (LSPR) has been applied in photovoltaic devices to improve their photoelectric conversion efficiency. In this study, the mechanism of LSPR dye-sensitized solar cells (DSSCs) was determined. Specifically, silver nanoparticles were formed by evaporating electro-beam equipment and then annealing it a tube furnace. The sizes varied with changes thicknesses during evaporation annealing. A DSSC-based graphene designed consist different metal assembled on cathode electrode. photon electric performance DSSCs, which depended Ag nanoparticles, analyzed detail, particular focus nanoparticle size. Compared DSSC without exhibited excellent current density incident photon-to-current efficiency (IPCE) due effect. 10 nm-thick film annealed form high IPCE 70.03%. value 45.15% higher than that pure graphene-based (31.62%). However, increased certain degree became aggregated concatenated, thereby decreasing effect DSSCs. Therefore, plays an important role photon-electrical

Photocurrent enhancement by surface plasmon resonance of silver nanoparticles in highly porous dye-sensitized solar cells.
Localized surface plasmon resonance (LSPR) by silver nanoparticles that are photochemically incorporated into an electrode-supported TiO(2) nanoparticulate framework enhances the extinction of a subsequently adsorbed dye (the ruthenium-containing molecule, N719). The enhancement arises from both an increase in the dye's effective absorption cross section and a modest increase in the framework s...

We demonstrated the localized surface plasmon resonance (LSPR) effect of Ni nanoparticles (NiNPs) on the performance of dye-sensitized solar cells (DSSCs). Our study revealed that NiNPs in a conventional I(-)/I3(-) electrolyte (NiNPs@I(-)/I3(-)) increased the net optical absorption of a N719 dye over a broad wavelength range by LSPR, and concurrently improved the power conversion efficiency (PC...

These cells could offer the same ease of manu...
متن کاملTemperature effects in dye-sensitized solar cells.
In the standard solar cell technologies such as crystalline silicon and cadmium telluride, increments of temperature in the cell produce large variations in the energy conversion efficiency, which decreases at a constant rate. In dye solar cells the efficiency remains roughly constant with a maximum at around 30-40 °C and further decays above this temperature. In this work, the origin of this c...
