  • Filter body for a soot filter
    Publication number: 20060051271
    Abstract: Filter body with internal cavities for use in particulate filters for internal combustion engines, which is preferably produced using micro-patterning processes employed in semiconductor technology, such as for example etching or patterned deposition. Integrated resistance heating can be realized by means of the choice of an electrically conductive material for the filter body.

  • Silicon-germanium solar cell having a high power efficiency
    Patent number: 6670544
    Abstract: A silicon-germanium thin-film solar cell having a quantum well structure as an active base layer within the space-charge region of the silicon p-n diode junction. The quantum well structure is composed of a sequence of silicon and germanium layers. In this manner, a highly absorbent base layer is produced in a silicon solar cell.
