Abstract:
Solar modules are provided that include a front pane, an inter layer into which solar cells are embedded, and at least one back side foil, which increases the life span of the solar modules. The at least one back side foil is provided with holes having a density of at most 0.2 cm−2.
Abstract:
A method and apparatus for producing a multiplicity of holes in thin sheet-like workpieces of dielectric material or semiconductors is provided. The perforation points are marked by HF coupling points and caused to soften using HF energy in order to obtain dielectric breakdowns. The breakdowns are then widened into holes.
Abstract:
An apparatus for producing holes in dielectric workpieces in the form of thin sheets and substrates, in particular of glass or glass-like materials and semiconductors is provided. The apparatus includes individual high-voltage electrodes that are symmetrically arranged on an electrode holder around the hole to be produced in the workpiece. The apparatus also includes individual counter electrodes that are arranged on a counter electrode holder. The electrodes and counter electrodes can be connected in a permutating manner to a high-voltage source for the discharge of high-voltage flashovers.
Abstract:
In many engineering production processes, for example glass or glass-ceramic manufacturing processes, liquids, such as glass melts, participate in the processes in which gases are dissolved, which in part form bubbles in the liquid. So that the quality of the final product is not disadvantageously influenced, the liquid, e.g. glass melt, should be refined to remove the bubbles. According to the method of the invention an overpressure acting on the liquid is provided which is such that the internal pressure in the bubbles immediately under the surface of the liquid in a refining chamber is at least as great as the sum of equilibrium pressures of the gases dissolved in the liquid and the sum of the vapor pressure of components evaporating from the liquid. A two stage apparatus is provided which performs a preferred embodiment of the refining method of the invention. This two stage apparatus includes a tower-like comparatively higher low pressure refining chamber (6) and a downstream comparatively lower overpressure refining chamber (1).

Abstract:
Methods and apparatuses for producing a multiplicity of holes in thin workpieces made of glass or glass-like materials and semiconductors are provided. The method includes directing multiple laser beams onto predetermined perforation points of the workpiece in a wavelength range between 1600 and 200 nm and with a radiation intensity that causes local non-thermal destruction of the workpiece material along respective filamentary channels. Subsequently, the filamentary channels are widened to the desired diameter of the holes.
Abstract:
The improved photovoltaic module contains a solar cell made of metallic silicon, which is embedded in at least one embedding material, and a corrosion inhibitor. Preferably the corrosion inhibitor is an organic compound, which has at least one nitrogen atom. As a result, the photovoltaic module according to the present invention has an extended service life, since it withstands corrosive influences.
