Title: Method for contact separation of electrically conductive layers on back-contacted solar cells and solar cell
Inventor: MUELLER JORG
IPC: H01L31/068
Filed: 2005-10-13
Abstract: A method for production of a solar cell (1), comprising a semiconductor substrate (2), is disclosed, the electrical contact of which is achieved on the back face of the semiconductor substrate. The back face of the semiconductor substrate comprises locally doped regions (3). The adjacent regions (4) have a different doping from said region (3). According to the invention, short-circuiting of the conducting material (5) of the solar cell may be avoided, whereby both regions (3,4), at least at the boundaries (6) thereof, are coated with a thin electrically-insulating layer (7). Both regions (3,4) are then coated over the whole surface thereof with an electrically-conducting material (5). The separation of the electrically-conducting layers (5) is achieved by application of an etching barrier layer (8) to the whole surface, which is then selectively removed without a mask, for example by laser ablation, locally above the insulating layer (7). By the subsequent attack of an etching solution the etching barrier layer (8) is locally removed from the conducting layer (5) in the region of the openings (9).

Inventor: LU GUANG
IPC: H04J99/00
Filed: 2006-03-17
Abstract: A method and system for performing dynamic link selection (DLS) between transmit/receive units (TRUs). A first TRU determines whether a second TRU has multiple interfaces with a DLS capability. If the second TRU has multiple interfaces with the DLS capability, the first TRU sends a packet to the second TRU through a selected link. The first TRU then receives a report from the second TRU and evaluates quality of the link based on the report. The first TRU selects a link for a new packet in accordance with a predetermined criteria and the quality of the link. If the second TRU does not have multiple interfaces with the DLS capability, the first TRU periodically sends probe packets to the second TRU via all available links. The second TRU sends response packets and the first TRU evaluates the quality of link based on statistics of the response packets.
