    • Disclosed are a configuration for bonding a thin metal layer to two workpieces {B} and {A}, e.g. solar cells and film-backed/reinforced small contact strips as well as a method for the stable production of such a connection, comprising the following steps: (i) the backing film is removed from the solar cell; (ii) the two films/layers are pressed together; and (iii) the two parts are irradiated from the side of the rear contact {} of the thin-film solar cell. According to the invention, preferably two or three laser treatment steps are used for removing the backing film of the thin-film solar cell in an ablation process by means of a short-pulse laser and riveting the first metal layer, e.g. the rear contact of the solar cell, to the second metal layer, e.g. the small contact strip, by irradiating the same by means of a long-pulse laser. The energy density, pulse duration and temporary pulse form, pulse frequency, and wavelength for the ablation process and the welding/riveting process are selected according to the specific materials used. Such a laser riveting process can be used for electrically contacting thin-film solar cells with small flexible contact strips.

    • The invention relates to a path sensor (1a; 1b; 1c) comprising at least one magnetoelectric transformer element (5) and a magnetic circuit with at least one flux conductor path (3, 4; 9, 10; 14, 15) and at least one magnet (2; 11). Said path sensor is smaller in size. The influence on magnetic flux caused by displacement of an object can be measured by the transformer element (5). The flux conductor path (3, 4; 9, 10; 14, 15) and the transformer element (5) are arranged in an unaltered position in relation to each other during the measuring of the path. Said parts (3, 4, 5; 9, 10; 14, 15) and the at least one magnet (2; 11) can be displaced relative to each other. Modification of the magnetic field which can be evaluated by the transformer element (5) is carried out by modifying the air gap (d) in the magnetic circuit during the displacement of the magnet (2; 11). The contour of the flux conductors parts (3, 4; 9, 10; 14, 15) of the magnetic circuit surround the path of the magnets (2, 11) in such a manner that modification of the width (d) of the air gaps in the course of the path (6; 12) results in a predetermined signal progression in the transformer element (5).
