Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic cell quartz boats and relates to a novel TOPCon quartz boat detection device. Background Art

[0002] In the manufacturing process of solar crystalline silicon cells, a tool called a quartz boat is used. The quartz boat is provided with teeth. The teeth play an important role in the production of photovoltaic cells. Its role is mainly reflected in the following aspects: 1. Positioning and fixing parts: The design of the teeth enables various parts in the production process of photovoltaic cells to be accurately positioned and fixed on the quartz boat. This helps to ensure the stability and consistency of the parts during the heating and sintering process, thereby improving the quality and performance of photovoltaic cells. 2. Improve heating efficiency: Through the design of the teeth, the quartz boat can transfer heat to the parts more effectively. The teeth increase the contact area between the quartz boat and the parts, so that the heat can be distributed more evenly, thereby improving the heating efficiency. 3. Optimize the sintering process: The structure of the teeth helps to optimize the sintering process. During the sintering process, the teeth can guide the flow of heat to ensure that the parts are sintered at the correct temperature and time. This helps to reduce defects and defective product rates during the sintering process and improve the yield and performance of photovoltaic cells.

[0003] In the existing TOPCon process route, the amount of quartz boat used is large, so the inspection requirements are very high and cumbersome. At present, there is no effective detection method in the industry. For example, CN201410334692.3 is a quartz boat insertion device, but it does not describe how the quartz boat slot detection mechanism performs detection. The quartz boat can only be judged by its automated appearance. This will have side effects on both the early inspection and the subsequent material control, on-site control and cost control.

[0004] In summary, a novel TOPCon quartz boat detection device and detection method are proposed in the utility model. Summary of the invention
