| 20110030773 | PHOTOVOLTAIC CELL WITH BACK-SURFACE REFLECTIVITY SCATTERING - Crystal oriented photovoltaic cells with increased efficiency are disclosed herein. In an exemplary embodiment, a photovoltaic device includes a metal substrate with a crystalline orientation comprising a diffracting structure integrated into a surface of the metal substrate. The photovoltaic device includes a heteroepitaxial crystal silicon layer having the crystalline orientation of the metal substrate and a heteroepitaxially grown buffer layer having the crystalline orientation. The buffer layer is positioned adjacent to the surface of the metal substrate having the diffracting structure. | 02-10-2011 |

| 20110146791 | EPITAXIAL GROWTH OF SILICON FOR LAYER TRANSFER - Methods of preparing a thin crystalline silicon film for transfer and devices utilizing a transferred crystalline silicon film are disclosed. The methods include preparing a silicon growth substrate which has an interface defining substance associated with an exterior surface. The methods further include depositing an epitaxial layer of silicon on the silicon growth substrate at the surface and separating the epitaxial layer from the substrate substantially along the plane or other surface defined by the interface defining substance. The epitaxial layer may be utilized as a thin film of crystalline silicon in any type of semiconductor device which requires a crystalline silicon layer. In use, the epitaxial transfer layer may be associated with a secondary substrate. | 06-23-2011 |

| 20090071503 | METHOD AND DEVICE FOR TREATING SUBSTRATES AND NOZZLE UNIT THEREFOR - A method and device for treating substrates, and a nozzle unit therefore. A liquid film is formed on a local surface area of a substrate that is to be treated by means of a nozzle unit comprised of at least on elongated nozzle arrangement and an ultrasonic or megasonic transducer arrangement disposed adjacent to the nozzle arrangement. The transducer arrangement is composed of a plurality of transducers having different resonant frequencies. At least a portion of the transducer arrangement is brought into contact with the liquid film, and ultrasound or megasound is introduced into the liquid film by the transducer arrangement. The transducers are excited individually and/or in groups with different intensities and/or frequencies, | 03-19-2009 |

| 20080319610 | Method and Device for Avoiding and/or Reducing the Consequences of Collisions Upon Evasion with Respect to Obstacles - A method and a device for assisting a driver of a vehicle to avoid collisions with obstacles are provided, in which method at least one obstacle is detected by way of at least one surroundings sensor, and data of the obstacle are ascertained. On the basis of the data of the obstacle and data of the vehicle, a vehicle deceleration that is favorable for assistance of an evasive operation is ascertained, and the vehicle is correspondingly decelerated. | 12-25-2008 |
| 20110106361 | Method for the calculation of a collision-preventing trajectory for a driving maneuver of a vehicle - A method for calculating a collision-avoiding trajectory for a driving maneuver of a vehicle, in particular a motor vehicle, in order to evade at least one obstacle approaching the motor vehicle during driving operation. The lateral speed of the motor vehicle is taken into account in the calculation independently of the longitudinal speed of the motor vehicle. | 05-05-2011 |
