| 20110318872 | SILICON SOLAR CELL - A silicon solar cell includes a first silicon layer with an emitter layer which has a thickness in a range of 50 nanometers to few hundreds nanometers. The emitter layer has at least one region which is porosified by chemical or electrochemical etching, wherein at least one part of the porosified region is embodied as metal silicide layer. A second silicon layer is disposed underneath the emitter layer, with the metal silicide extending from a top side of the emitter layer in a direction to the second silicon layer. At least one metal layer is applied on the metal silicide layer. | 12-29-2011 |

| 20110006874 | MICROMECHANICAL ACTUATOR - A micromechanical actuator includes a movable first spring element having metal and/or silicon. The first spring element is fitted at a first point and can move freely at a second point. A second spring element connected to the first spring element has silicon and is partially arranged on an electrically insulating material which is applied to a substrate. The second spring element is arranged at a distance from the substrate above the substrate on a first plane, and the first spring element is arranged above the second spring element on a second plane which is at a distance from the first plane such that the first and second spring elements can move with respect to the substrate. The actuator has a third spring element which is mechanically coupled to the first spring element. The elastic deformation of the second spring element can be induced by a length change of the third spring element. | 01-13-2011 |
