Apparatus and Method for Mounting Contact Wires on Solar Cell Wafers

A device and a method for fitting solar cell contact wires providing a series connection, and which run continuously in a string direction to join a front solar cell wafer and a rear solar cell wafer. The device includes a wire-laying mechanism having a wire feed gripper, a wire transport gripper movable in the string direction relative to the wire feed gripper, a wire-holding gripper to grip and hold the contact wires behind the wafer-holding position for the rear solar cell wafer, and a wire cutter. Once a front solar cell wafer has been positioned, the contact wires are transferred from the wire feed gripper to the wire transport gripper, are advanced in the string direction over the wafer-holding position, are gripped and held by the wire-holding gripper, and are then cut behind the wire-holding gripper by the wire cutter.
