Embodiment Construction

[0081] The present invention will be further described below in conjunction with accompanying drawing.

[0082] Such as figure 1 As shown, the present invention is used to produce "IBC solar cell strings". The structure of the IBC solar cell string is as follows figure 1 As shown, it includes six or twelve cells A and multiple welding ribbons B (when six cells are connected to form a battery string, the cells used are full-piece cells; twelve cells are connected to form a battery string , the cells used are half-cell cells). Each battery sheet A is arranged at equal intervals in turn. Two adjacent cells A are connected by a set of ribbons B. There are four welding ribbons B in one set, and they are arranged along the direction vertical to the arrangement of battery sheets. The two ends of the four welding ribbons B respectively cover the opposite edges of the two adjacent battery sheets A. Adjacent two groups of soldering strips are staggered; therefore, any battery shee...

Abstract

The invention discloses an IBC solar cell string welding strip welding production line and a production method thereof. Compared with a conventional tabber and stringer in which the position of a metal wire is fixed by using a latter cell piece, an IBC cell cannot achieve the effect, and a net pressing clamp is needed for covering and fixing. The IBC solar cell string welding strip welding production line comprises a cell arrangement module, welding strip adding modules, a final welding module and a cell string transferring module, wherein the cell arrangement module, the welding strip addingmodules and the final welding module are sequentially arranged; and the cell string cell module is arranged at the output ends of the welding strip adding modules and transfers cell strings output bythe welding strip adding modules to the final welding module, and the welding strip adding modules comprises middle racks, welding strip feeding devices, welding strip transferring devices, light welding devices, clamp backflow devices, third cell conveyors, clamp conveyors and pressing positioning clamps. The IBC solar cell string welding strip welding production line and the production method thereof can realize full-automatic arrangement, preliminary welding and final welding of cell pieces.

Description

technical field [0001] The invention belongs to the technical field of solar cell production equipment, and in particular relates to an IBC solar cell string ribbon welding production line and a production method thereof. Background technique [0002] IBC battery (full back electrode contact crystalline silicon photovoltaic cell) is a technology that moves both the positive and negative metal contacts to the back of the cell, so that the front of the cell facing the sun is completely black, and the front of most photovoltaic cells is completely invisible. metal wires. This not only brings more effective power generation area to users, but also helps to improve power generation efficiency, and the appearance is also more beautiful. The biggest feature of the IBC battery is that the PN junction and metal contact are on the back of the battery, and the front is not affected by the shielding of the metal electrode, so it has a higher short-circuit current Jsc, and the back can ...
