20130220396 | Photovoltaic Device and Module with Improved Passivation and a Method of Manufacturing - A photovoltaic device, having an improved passivation of surfaces, such as a circumferential outer wall and/or an aperture wall of a back contact metal wrap-through photovoltaic device, for example, into which the pn-junction of first and second semiconductor layers extends. The passivation comprises a passivating layer of a first type, covering at least part of such wall substantially comprised by the depletion region across the pn-junction; a passivating layer of a second type, covering at least part of such wall comprised by the first semiconductor layer, and a passivating layer of a third type covering at least part of the outer wall comprised by the second semiconductor layer. | 08-29-2013 |

20150133260 | PLANETARY GEAR STAGE WITH PLAIN BEARINGS AS PLANET BEARINGS AND USE THEREOF - A planetary gear stage for a gearbox has a ring gear, a sun gear and a planet carrier for driving planet shafts. Each planet shaft has a planet gear with radial and axial contact surfaces and which is rotatably supported by a plain bearing arrangement. The bearing arrangement has two bushings fixed to the planet shaft. Each bushing is L-shaped in cross-section and has radial and axial contact surfaces. The bushings form a cross-sectional U-shape and are axially locked by abutments. At least part of the planet gear is located within the U-shape formed by the bushings. The plain bearing arrangement has a radial sliding support arranged between the radial contact surface of the bushings and the radial contact surface of the planet gear and an axial sliding support arranged between the axial contact surface of the bushings and the axial contact surface of the planet gears. | 05-14-2015 |
