Abstract: A method for producing a thermoelectric generator includes a preparation step, a connection step and an insertion step. In the preparation step, a first substrate, a thermoelectric generator material and a second substrate are prepared. In the connection step, the generator material is connected to the first substrate and the second substrate. In this way, a first side of the generator material is connected to the first substrate in a thermally and electrically conductive manner. A second side of the generator material, opposite the first side, is connected to the second substrate in a thermally and electrically conductive manner. In the insertion step, a support material is inserted between the first substrate and the second substrate, in order to support the first substrate and the second substrate against each other and/or to mechanically connect them together.

Abstract: A laser diode device includes a thermally conductive substrate that has a planar surface for dissipating ambient heat, and a plurality of laser diodes situated thereon, each of which includes at least one epitaxial layer that is situated on a side of the laser diode facing the substrate. The laser diodes are each electrically activated via an electrically conductive coating situated between the at least one epitaxial layer and the substrate. The substrate includes a plurality of metallized cavities that accommodate the plurality of laser diodes so that the plurality of laser diodes have an essentially uniform height above the substrate.

Abstract: A thermoelectric device includes a printed circuit board, a component which is arranged on the printed circuit board, a cover which covers the printed circuit board, a thermoelectric generator, and a spring unit. The thermoelectric generator is thermally connected to the printed circuit board or metal paths on the printed circuit board and to the cover in order to generate an electric supply voltage for the component from the temperature difference between the printed circuit board and the cover. The spring unit elastically holds the thermoelectric generator between the printed circuit board and the cover.
