  • Method and device for producing solar cells
    Patent number: 6734037
    Abstract: The present invention concerns a process for fabricating a solar cell, wherein material is deposited on a multicrystalline silicon substrate and passivation is performed by means of hydrogen plasma. It is proposed that the material be deposited by low-pressure CVD and the hydrogen passivation be effected by feeding in a hydrogen plasma induced remotely from the partially processed solar cells. A device for carrying out the process is also described.

  • Transport device and method of transporting to-be-processed elements through a high-temperature zone
    Patent number: 6705457
    Abstract: A transport device for transporting to-be-processed elements through a high-temperature zone and a corresponding method is described. The transport device operates according to the walking beam principle, with thin, elongated carrier elements made of a flexible material, which are maintained under tensile stress along the longitudinal axis of the carrier elements, being provided instead of conventional walking beams. The device permits low contamination transport of the elements through a high-temperature zone and improved utilization of energy as well as the ability to use a RTP process.

  • Process and device for treatment of sheet objects in a liquid bath
    Patent number: 6306224
    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.
