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.

Abstract: A process and device for treating sheet objects, especially fragile sheet objects, by rotation through a liquid bath. The objects are disposed in radial slots in a rotating disk, retained therein by a flexible element moving synchronously with the disk, and by a retaining element mounted adjacent the disk and spaced therefrom along its axis of rotation.

Abstract: The invention relates to a process for heat treatment of two-dimensional objects such as semiconductor wafers, for example in the form of silicon wafers, where the objects are arranged on supports and are conveyed through a heating unit, in particular continuously. To achieve a targeted treatment of a two-dimensional object, in particular of a semiconductor component such as a silicon wafer, on one side only, while at the same time achieving a high throughput with incorporation as necessary into a continuous overall manufacturing process, it is proposed that the objects be arranged in full surface contact with the supports, which cover the objects completely or almost completely on their underside and which in turn comprise quartz glass in particular.
