Yttrium deposition on mesoporous TiO2: Textural design and UV decolourization of organic dyes
(2015)
This study discusses about the photochemical, topological and textural properties of yttrium-doped titanium dioxide (TiO2) photocatalysts. The mesoporous yttrium-doped TiO2 substrates prepared in this research work operate ...
Surface Passivation of Nanoporous TiO2 via Atomic Layer Deposition of ZrO2 for Solid-State Dye-Sensitized Solar Cell Applications
(Amer Chemical Soc, 2009-10-22)
We report here the utilization of atomid layer deposition to passivate surface map states in mosoporous TiO2 nanoparticles for solid state dye sensitized solar cells based on 9,9'-spirobifluorene (spiro-OMeTAD). By depositing ...
Anomalous photocurrent response of hybrid TiO2:P3HT solar cells under different incident light wavelengths
(Elsevier Science, 2016-12)
Ordered mesoporous titania present optimum optical and electronic characteristics for solar cells applications. Hybrid solar cells that combine a dye polymer and porous titania is being studied as an inexpensive alternative ...
Role of Polyelectrolyte for Layer-by-Layer Compact TiO(2) Films in Efficiency Enhanced Dye-Sensitized Solar Cells
(AMER CHEMICAL SOC, 2010)
Efficient compact TiO(2) films using different polyeleetrolytes are prepared by the layer-by-layer technique (LbL) and applied as an effective contact and blocking film in dye-sensitized solar cells (DSCs). The polyanion ...
Influence of the Sol-Gel pH Process and Compact Film on the Efficiency of TiO2-Based Dye-Sensitized Solar Cells
(HINDAWI PUBLISHING CORPORATIONNEW YORK, 2012)
The influence of pH during hydrolysis of titanium(IV) isopropoxide on the morphological and electronic properties of TiO2 nanoparticles prepared by the sol-gel method is investigated and correlated to the photoelectrochemical ...
Impedance Spectroscopy Analysis of the Effect of TiO2 Blocking Layers on the Efficiency of Dye Sensitized Solar Cells
(Amer Chemical Soc, 2012-06-14)
The introduction of a dense TiO2 layer between the mesoporous TiO2 network and the charge collector in dye-sensitized solar cell anodes has been claimed to improve the performance of solar cell devices. Two mechanisms have ...
