The invention provides a curing and passivating integrated furnace for use in solar cell production. The curing and passivating integrated furnace comprises a furnace body, a transport channel, a curing and passivating area and a light source system, wherein the transport channel is formed in the furnace body, and extends along the length direction of the furnace body; the curing and passivating area is formed in the same segment of the furnace body; and the light source system is arranged in the curing and passivating area, and can be taken as a curing heat source and an irradiation light source at the same time. Through adoption of the curing and passivating integrated furnace, the curing and passivating processes of solar cells are realized at the same time through the light source system arranged in the curing and passivating area; the process is simplified; the curing and passivating effects are ensured; and the manufacturing cost and floor area of equipment are reduced. The curing and passivating integrated furnace is particularly suitable for the production and preparation of HJT cells.
Description
technical field [0001] The invention relates to the technical field of photovoltaic production, in particular to an integrated curing and passivation furnace for solar cell production. Background technique [0002] Compared with other renewable energy sources, solar power generation technology has many outstanding advantages. In comparison, crystalline silicon solar cells are still the most widely used photovoltaic products in domestic and foreign markets due to their low cost of raw materials and relatively mature technology. As far as crystalline silicon solar cells are concerned, their industrialization technology is relatively mature, but the requirements for cell conversion efficiency and stability in domestic and foreign markets are still improving. [0003] The HJT battery is mainly to deposit the intrinsic α-Si:H layer on the front / back side of the n-type silicon wafer, and then deposit the p-type α-Si:H layer and the n-type α-Si:H layer respectively, and then carry...
