We introduce the concept and first experimental tests of the wire cell. The front electrode of this otherwise standard crystalline silivon solar cell consists only of thin parallel fingers wich are reinforced by thin wires soldered onto them. The wires are condinued to the back side of the next cell where contact is formed by pressure, allowing for an uninterrupted aluminium back surface field. For a multicrystalline silicon solar cell of (156mm)² the gain in power should be over 100 mW, or 3% relative. First tests on (150mm)² standard cells confirmed a relative gain up to 2%. Deteils of the soldering technology are also presented.
