An electrode for contacting an electrically conductive surface of a photovoltaic element includes an electrically insulating optically transparent film, an adhesive layer provided on a planar surface of the film, and a plurality of substantially parallel, electrically conductive wires embedded into the adhesive layer. The plurality of wires lies over the planar surface of the film. A part of the surfaces of the wires protrude from the adhesive layer. At least the part of the surfaces protruding from the adhesive layer are covered by a coating consisting of an alloy having a low melting point to solder the wires to the electrically conductive surface and to a first terminal bar. The adhesive layer has a thickness less than the thickness of the wires embedded therein.

Electrode for photovoltaic cells, photovoltaic cell and photovoltaic module

A solar cell apparatus and process for making and using same involving a semiconductor wafer having a front side surface and a metallized back side surface and a semiconductor p/n junction between the front side surface and the back side surface. At least one front side interruption is caused to extend along at least a portion of the front side surface and into the wafer to a depth sufficient to interrupt the semiconductor p/n junction to define a plurality of separate p/n junction sections within the wafer and to define separate front side surface portions associated with respective separate p/n junction sections. A back side interruption is caused to extend along a portion of the metallized back side surface, generally opposite the front side interruption, to define a plurality of separate metallized back side surface portions associated with respective p/n junction sections and in electrical contact with respective p/n junction sections.
