摘要： In different embodiments, a method is provided for processing at least one crystalline Silicon-wafer or a Solar-cell wafer. The method may include: a movement of the wafer with respect to a laser producing a laser beam; and therefore the formation of a laser channel in the wafer by means of a laser beam, wherein a thermal budget applied on the wafer by means of the laser beam is reduced in the peripheral region of the wafer, wherein the peripheral region includes a wafer edge, through which the laser beam exits the wafer after formation of the laser channel.

摘要： A bifacial photovoltaic module with at least one bifacial solar cell is provided. The at least one bifacial solar cell includes a substrate with a front-side and a rear-side. The front-side is the light incident side and the rear-side has rear-side contact structure. The rear-side contact structure includes a plurality of electrically conductive contact fingers, which have a first metal, a plurality of solder pads electrically connected to the contact fingers. The solder pads have a top. The solder pads have a second metal, which is different from the first metal. The rear-side contact structure further includes several cell connectors electrically connected to the solder pads. The top of the solder pads is free from the contact fingers in an area along one direction. The cell connectors are disposed planar on or above this area.
