Fabrication and photovoltaic properties of dye-sensitized ZnO thick films by a facile doctor-blade printing method using nanocrystalline pastes

Dye-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...

Optical Studies and Photovoltaic Performance of Nanocrystalline Titanium Dioxide Sensitized with Local Dye

Nanocrystalline titanium (iv) oxide paste has been deposited on Fluorine doped tin oxide glass substrate by the blade method. The deposited film was subjected to thermal treatment to obtain an electrode foe a photo-electrochemical cell. The electrode was sensitized with prophyrin dye which was a local dye extracted from carica papaya leaves. Avaspec 2.1 spectrophotometer was used to obtain the ...

Facile fabrication of co-sensitized plastic dye-sensitized solar cells using multiple electrophoretic deposition.

We present the proof of concept of a new method for the rapid fabrication of co-sensitized plastic dye sensitized solar cells with dyes arranged in discrete layers. Using D131 and SQ2 in the devices, the layered method gives an efficiency of 4.1% on plastic substrates. This is a significant improvement over cocktail devices which give only an efficiency of 3.3%.

Structure and photovoltaic properties of ZnO nanowire for dye-sensitized solar cells

Aligned ZnO nanowires with different lengths (1 to approximately 4 μm) have been deposited on indium titanium oxide-coated glass substrates by using the solution phase deposition method for application as a work electrode in dye-sensitized solar cells (DSSC). From the results, the increases in length of zinc oxide (ZnO) nanowires can increase adsorption of the N3 dye through ZnO nanowires to im...
