摘要:
A surface coating for lightning protection is embodied as a composite material including a matrix formed from a polysilazane or of a polysiloxane, and filled with lamellar, ceramic particles having an electrically conductive coating of metal oxide. The surface coating may be applied to a blade of a wind turbine by applying the conductive coating in liquid form to the blade, allowing the surface coating to harden at room temperature, and pyrolyzing the surface coating via short periods at temperatures up to 700° C. to form a glassy, electrically conductive coating that is resistant to temperature changes.

摘要:
Provided herein are conductive glass-metal compositions, as well as methods of making and using such compositions. In one example, the compositions include gold (Au) doped lithium-borate glasses shown to exhibit a transition from ionic to electronic conduction within the same sample. This is achieved via appropriate heat treatment, and particularly by heat treatment after annealing, wherein the post-annealing heat treatment is performed at temperatures below the glass transition temperature (Tg). The methods described herein are believed to introducing polarons formed from the trapping of electrons at partially ionized gold atoms. This unique electrical response provides new functionality to this class of nanocomposites. Additionally, increased thermal conductivity can be provided to an otherwise low conductive glass composition using the inventive methods and other subject matter provided herein.

摘要:
The invention relates to a process for manufacturing solar cells. The manufacturing process of the invention comprises the steps of printing a conductive paste onto an n-type silicon layer of a crystalline silicon substrate or onto an antireflection film on the n-type silicon layer, and drying and firing the conductive paste to form an electrode. The conductive paste comprises a conductive powder, a glass frit and an organic vehicle. The glass frit comprises at least one oxide. X-ray photoelectron spectroscopy of the glass fit gives a spectrum representing binding energies of oxygen in which the signal intensity of a peak with a peak top at a range from 529 eV to less than 531 eV has a proportion of 40% or more relative to the total of signal intensities from 526 eV to 536 eV.
