摘要： Approaches for fabricating wire-based metallization for solar cells, and the resulting solar cells, are described. In an example, a solar cell includes a substrate having a back surface and an opposing light-receiving surface. A plurality of alternating N-type and P-type semiconductor regions is disposed in or above the back surface of the substrate. A conductive contact structure is disposed on the plurality of alternating N-type and P-type semiconductor regions. The conductive contact structure includes a plurality of metal wires. Each metal wire of the plurality of metal wires is parallel along a first direction to form a one-dimensional layout of a metallization layer for the solar cell.

摘要： Laser foil trim approaches for foil-based metallization of solar cells, and the resulting solar cells, are described. For example, a method of fabricating a solar cell includes attaching a metal foil sheet to a surface of a wafer to provide a unified pairing of the metal foil sheet and the wafer, wherein the wafer has a perimeter and the metal foil sheet has a portion overhanging the perimeter. The method also includes laser scribing the metal foil sheet along the perimeter of the wafer using a laser beam that overlaps the metal foil sheet outside of the perimeter of the wafer and at the same time overlaps a portion of the unified pairing of the metal foil sheet and the wafer inside the perimeter of the wafer to remove the portion of the metal foil sheet overhanging the perimeter and to provide a metal foil piece coupled to the surface of the wafer.

摘要： The invention relates to a method for metallizing and connecting solar cell substrates and to a photovoltaic module made of several metallized solar cells that are electrically connected to one another. According to the invention, a solar cell substrate, in which second metal layers forming electrical metal contacts are optionally provided, is attached to a carrier substrate, on the surface of which at least one first metal layer is formed in a suitable pattern. By localized irradiation of the metal layer with laser radiation through the solar cell substrate or the carrier substrate, energy is introduced such that the metal layer is heated by absorbed laser radiation for an irreversible bonding to the adjacent surface of the solar cell substrate. By the laser bonding of the metal layer on the carrier substrate to the solar cell substrate, solar cells can be connected to form a photovoltaic module.

摘要： The invention relates to a heterojunction solar cell and a method for the production thereof. The heterojunction solar cell has an absorber layer made of silicon with a basic doping and at least one heterojunction layer of a doped semiconductor material whose band gap differs from that of the silicon of the absorber layer. The absorber layer has a doped layer at an interface directed toward the heterojunction layer, the doping concentration of said doped layer being greater than the basic doping concentration of the absorber layer. As a result of this doping profile, a field effect can be caused which prevents charge carrier pairs produced within the absorber layer from diffusing toward the interface between the absorber layer and the heterojunction layer and from recombining there.

摘要： The invention relates to a rear-contact solar cell and to a method for producing the same, wherein elongate emitter regions (5) and elongate base regions (7) are defined in a semiconductor substrate (1) in a finely interleaved manner on the surface of the rear side of the cell. The elongate emitter regions (5) are contacted by elongate emitter contacts (11) that extend at a right angle thereto, and the elongate base regions (7) are contacted by elongate base contacts (13) that extend at a right angle thereto, the structural width of the emitter and base regions (5, 7) being substantially smaller than the structural width of the emitter and base contacts. The finely interleaved arrangement of emitter and base regions (5, 7) results in good current collecting properties and low series resistances within the semiconductor substrate. Owing to the less complicated structures of the metal contacts, the latter can be produced in a simple and reliable manner.

摘要： The invention relates to a rear-contact solar cell and to a method for producing the same. The rear-contact solar cell comprises a semiconductor substrate on the rear side surface of which emitter regions, contacted by emitter contacts, and base regions, contacted by base contacts, are defined. The emitter regions and the base regions overlap at least in overlap regions, the emitter regions in the overlap regions reaching deeper into the semiconductor substrate than the base regions, when seen from the rear side surface of the solar cell. As a result, a large area percentage of the rear side of the semiconductor substrate can be covered with a charge-collecting emitter, said emitter being at least partially buried in the interior of the semiconductor substrate so that there is no risk of the base contacts provoking a short circuit towards the buried emitter regions.
