Nanoparticles influence on dye-sensitized solar cells based on TiO2
Today, Solar cell technology is in limited use due to the relatively high manufacturing cost of silicon based technology, And the low power efficiency of organic polymer based technology. However, Research is being done on hybrid cells based on dye-sensitizing organic polymers and a thin transparent conducting oxide layer comprised of nanoparticles. These cells could offer the same ease of manu...
متن کاملSiH/TiO2 and GeH/TiO2 Heterojunctions: Promising TiO2-based Photocatalysts under Visible Light
We use hybrid density functional calculations to find that the monolayer silicane (SiH) and the anatase TiO2(101) composite (i.e. the SiH/TiO2 heterojunction) is a promising TiO2-based photocatalyst under visible light. The band gap of the SiH/TiO2(101) heterojunction is 2.082 eV, which is an ideal material for the visible-light photoexcitation of electron-hole pairs. Furthermore, the SiH/TiO2(...
متن کاملFlexible Dye-Sensitized Nanocrystalline TiO2 Solar Cells
The Dye-sensitized nanocrystaline TiO2 solar cell (nc-DSC) developed by Grätzel [1] has the potential to reach low costs in future outdoor power applications. In addition, due to its expected ease of production and possibilities to adjust its appearance, the potential for application is very broad. When plastic foil is used as a substrate for the nc-DSC the production and application possibilit...
متن کاملDye-Sensitized Nanocrystalline Rutile TiO2 Films
Dye-sensitized nanocrystalline rutile TiO2 solar cells were prepared, and the influence of Li and 1,2-dimethyl3-hexyl imidazolium ions in the electrolyte on the photovoltaic properties was compared. The electrolyte containing Li ions produced a lower open-circuit photovoltage than the electrolyte with 1,2-dimethyl-3-hexyl imidazolium ions, suggesting that the adsorption of Li ions to the rutile...
متن کاملDye-sensitized TiO2 nanotube solar cells: rational structural and surface engineering on TiO2 nanotubes.
Owing to well-defined structural parameters and enhanced electronic properties, highly ordered TiO(2) nanotube arrays have been employed to substitute TiO(2) nanoparticles for use in dye-sensitized solar cells. To further improve the performance of dye-sensitized TiO(2) nanotube solar cells, efforts have been directed toward the optimization of TiO(2) photoanodes, dyes, electrolytes, and co...
