A fixture for photovoltaic cell electroplating

Abstract

The invention discloses a fixture for photovoltaic cell electroplating, which includes a flower basket and a motor. The peripheral side of the motor is fixedly connected to a fixing seat, the output shaft of the motor is fixedly connected to one end of a rotating shaft, and the end of the rotating shaft away from the motor is fixedly connected to a limiting disk. , the rotating shaft is provided with an external thread on the peripheral side near the end, and is screwed to the inside of the first fixed block, the first fixed block is fixedly installed on one side of the movable plate, and the other side of the movable plate is fixedly connected to the second fixed block. block, the inside of the second fixed block is slidably connected with a slide bar, and the middle part of the rotating shaft and the slide bar is connected to the limit seat, and the limit seat is fixedly installed on the outside of the flower basket. The chute, the inner side of the chute is slidably connected to the slider, and the clamping block is used to clamp and fix the surface, which is conducive to improving the uniformity of electroplating, so that the clamping force is evenly distributed on the surface of the silicon wafer, and the silicon wafer is prevented from being damaged by the clamp. Fragments, hidden cracks.

Description

technical field [0001] The invention relates to the technical field of solar cells and semiconductor manufacturing, in particular to a fixture for photovoltaic cell electroplating. Background technique [0002] Crystalline silicon solar cells usually use screen printing silver paste and then sintered at high temperature or low temperature to form metal electrodes to export photogenerated carriers, which is currently the most widely used metallization method for crystalline silicon solar cells. This method has a simple process and is currently the mainstream mass production process. In recent years, with the continuous development of silicon wafer and battery technology, the production cost of solar cells has continued to decline, and the cost of expensive silver paste in the metallization process is the largest in the entire battery cost. The proportion of the silver electrode is constantly increasing, and the width and aspect ratio of the silver electrode are limited by the...
