The dye solar cell, is a novel photoelectrochemical solar cell presenting unique advantages, as the use of low cost materials and the potential simplicity of manufacturing. However, a liquid electrolyte is actually required for the transport of the photoge ...
One embodiment of this invention relates to a substrate (3) having a crystalline tin (IV) oxide film grown thereon, the film comprising a plurality of nanorods each of hick includes crystals grown along the c-axis of the tin (IV) oxide crystal. Another emb ...
Thin films consisting of nanorods of hematite (α-Fe2O3) with controlled orientation onto transparent conductive glass substrates have been tested as photoelectrochem. cells. These films allow a more efficient transport and collection of photogenerated elec ...
Nanostructured ZnO films consisting of 150-nm sized particles were dye-sensitized with different ruthenium complexes. Incident photon-to-current conversion efficiencies were found to be dependent on dye concn. and on residence time of the ZnO film in the d ...
The effect of internal stresses on the cohesion and adhesion of a thin silicon oxide (SiOx) oxygen-barrier coating, evaporated on a poly(ethylene terephthalate) (PET) film substrate was studied. Internal stresses were generated during annealing in the temp ...
The advantages and limitations of photovoltaic solar modules for energy generation are reviewed with their operation principles and physical efficiency limits. Although the main materials currently used or investigated and the associated fabrication techno ...
Time-of-flight secondary ion mass spectrometry (ToF-SIMS) imaging is employed to characterize the surface of patterned noble metal (Pt) and titania (TiO2) thin films deposited on oxidized silicon wafers. ToF-SIMS is used to follow the different process ste ...
The effects of background n- and p-type doping on Zn diffusion in GaAs/AlGaAs multilayered structures are investigated by secondary-ion-mass spectrometry and photoluminescence measurements. Zn diffusions are performed at 575 degrees C into Si-doped, Be-dop ...
Zinc oxide (ZnO) is a material that belongs to the family of Transparent Conductives Oxides (TCO). Its non-toxicity and the abundant availability in the Earth's crust of its components make it an ideal candidate as electrical transparent contact for thin-f ...
A method for a binder-free manufg. a nanostructured porous film, e.g. for use in solar cells, comprises the steps of: prepg. a suspension of semi-conducting nanometer-sized particles in a volatile suspending agent , depositing the particle suspension on a ...
