The absorption spectra of most org. dyes reported thus far used for mesoporous nanostructured dye-sensitized solar cells mainly cover the visible-light region. This has motivated research towards the development of new types of org. dyes(7-10) with absorpt ...
The photocurrent-voltage characteristic of a photoelectrochemical cell for solar hydrogen production via water splitting, using undoped-hematite as photoanode, was obtained. Photoelectrochemical characteristics of the cell were also investigated by electro ...
Nitrogen and sulfur co-doped and N-doped TiO2 anatase TKP 102 (Tayca) were prepared by manual grinding with thiourea and urea, respectively, and annealing at 400 degrees C. Both materials showed visible-light absorption as measured by Diffuse Reflectance S ...
In the context of the diminishing fossil energy resources and global warming, much research is focused on sustainable energy sources. The research that is presented in this thesis falls in this category as it contributes to the development of a device that ...
A photosensitive plate based on sintered TiO2 nanoparticles has been developed to carry out in-source photo-induced reductions for cleavage of disulfide bridges using glucose as a hole scavenger during laser desorption ionization. ...
Techniques of TiO2 film fabrication for dye-sensitized solar cells having a conversion efficiency of global air mass 1.5 (AM 1.5, 1000 W/m(2)) solar light to electric power over 10% are reported. Newly implemented fabrication technologies consist of pre-tr ...
Zn stannate (Zn2SnO4) 27 nm particles were synthesized by hydrothermal treatment. Nano-porous Zn2SnO4 thin films were prepd. on conducting glass substrates and used as working electrodes in dye-sensitized solar cells (DSSCs). Their behavior was compared wi ...
Dye-sensitized solar cells (DSC), introduced by O'Regan and Grätzel in 1991, are a low cost alternative to conventional silicon photovoltaic cells, the latter requiring extremely pure starting materials and sophisticated production procedures. DSC's, based ...
Three different types of nanocryst., N-doped TiO2 electrodes were synthesized using several nitrogen dopants through wet methods. The obtained nanocryst., N-doped TiO2 electrodes possessed different crystallite sizes, surface areas, and N-doping amts. Char ...
Doping of nanocrystalline TiO2 powders with sizes ranging from 9.5 nm up to 19.1 nnn was carried out with thiourea (TU) to introduce the C, N and S-species into the TiO2. The crystal size was determined by X-ray diffraction. Doped-TiO2 particles were color ...
