摘要： A photovoltaic cell has a semiconductor substrate formed from semiconductor material doped by a first dopant type, and a doped region over at least a portion of the substrate. The doped region is doped by a second dopant type that is opposite to that of the first dopant type to form an emitter. Moreover, the doped region is doped to a region dopant level. In addition to the substrate and emitter, the cell also has a plurality of semiconductor fingers formed on the emitter, a plurality of busbars formed from a conductor and intersecting the plurality of semiconductor fingers, and a plurality of tabs soldered to the busbars. The fingers are doped by the second dopant type to have a second dopant level, which is greater than the region dopant level.

摘要： A shaped tab conductor configured to allow more incident light to strike a cell substrate, improving the photovoltaic efficiency of the cell. The shaped tab conductor is configured to reduce the amount of incident light that is blocked by the tab from reaching the surface of the cell substrate. The tab may also be configured to redirect light reflected from the cell surface back to the cell surface. The cross-section of the tab conductor may be polygonal, such as a rhombus, with at least one generally planar surface that forms an acute angle with the substrate.

摘要： A photovoltaic cell has a photosensitive substrate and a plurality of fingers in ohmic contact with the substrate. At least one of the fingers has an average width of less than about 95 microns. The cell also has a plurality of busbars in ohmic contact with the fingers. At least two of the busbars that are spaced less than about 38 millimeters apart intersect the at least one finger (i.e., the finger(s) having an average width of less than about 95 microns).
