Description

Technical Field

[0001] The utility model relates to the technical field of solar cell manufacturing, in particular to a solar cell carrying device. Background Art

[0002] With the continuous development of solar cell technology, cost reduction has become the primary direction of the photovoltaic industry. In traditional battery structures, the electrodes are mainly silver metal grid lines, but silver is a precious metal, and the price of silver paste increases with the rise in global silver prices. Therefore, solar cells using copper metal grid lines as electrodes have gradually emerged due to their low cost. The production of copper metal grid lines draws on the technology of the PCB industry, that is, first make a copper seed layer, then make a mask on it, and then physically or chemically groove to form an electrode pattern, and then electroplate copper metal grid lines, remove the mask, and then etch away the copper seed layer outside the metal grid lines to form copper metal grid line solar cells.

[0003] In the process of making masks, the industry currently uses basically photosensitive dry film and photosensitive wet film. Dry film is simple and easy to use in the process, but the price of dry film rises sharply as the resolution decreases. Photosensitive wet film has low cost, but the process is to coat the wet film and dry and solidify, which is relatively complicated. At present, the market basically uses a flower basket to carry the battery cells coated with wet film on both sides. The flower basket is provided with three placement rods with several slots, and the battery cells are inserted into the three slots of the placement rods for fixing. However, when the battery cell is inserted into the slot, the teeth rub against the surface of the battery cell, which poses a risk of damaging the wet film. At the same time, after the wet film is solidified, the wet film is easy to adhere to the teeth and is difficult to remove, causing production troubles. Therefore, how to dry and solidify the solar cell after double-sided coating with the least impact on the wet film state has become a difficult problem. Utility Model Content
