Embodiment 1

[0022] like figure 1 As shown, the roller table type solar cell irradiation annealing furnace is composed of a roller table 1, a light source 3, an upper furnace shell 4, a light-transmitting and heat-insulating material layer 5, a cooling fan 6, a lower furnace shell 7 and a heating device 8. The furnace shell 4 and the lower furnace shell 7 form a furnace cavity, and the roller table 1 is arranged in the horizontal direction and passes through the furnace cavity. The lower part is provided with a heating device 8, and a light source 3 is provided on the upper part of the irradiation annealing furnace. In the chamber where the light source 3 is installed, a blowing cooling device or an exhaust device for cooling the light source 3 is provided to cool the light source 3. The lower part of the light source 3 is provided with a light-transmitting and heat-insulating material layer 5, which separates the heating area from the light source 3, so as to prevent the heat from burning...

Embodiment 2

[0026] The battery sheet 2 travels horizontally under the transmission of the roller table 1, a light source 3 is installed at the lower part of the radiation annealing furnace, a heating device 8 is installed at the upper part of the radiation annealing furnace, and a The light-transmitting and heat-insulating material layer 5 separates the upper heating area from the light source 3 , and the rest are the same as in Embodiment 1.

Abstract

The invention relates to a roller-way-type solar cell irradiation annealing furnace which can be used for irradiation annealing treatment of solar cells. In the irradiation annealing furnace, cell pieces are transmitted on a group of horizontally-arranged roller ways, light sources and a heating device are arranged above and below the roller ways respectively or below and above the roller ways respectively, and the fronts face the light sources while the backs face the heating device when the cell pieces are transmitted. The cell pieces after being sintered are continuously transmitted through the roller ways, and irradiation annealing treatment is completed continuously in the process of horizontal advancing, so that the roller-way-type solar cell irradiation annealing furnace has the advantages of low energy consumption, stability in running, high capacity and continuous production, and the problem of attenuation in the process of using solar cells can be solved to greatest extent after the furnace is popularized and utilized.

Description

technical field [0001] The invention relates to a roller table type solar cell radiation annealing furnace, which can be used for radiation annealing treatment of solar cells. Background technique [0002] Normally, after the solar cell is sintered in a chain-type sintering furnace, it can be made into a module and put into a solar power station. Due to the existence of boron-oxygen pairs, the efficiency of solar cells will be attenuated in the long-term light environment during use, especially for the PERC cells that have emerged in recent years. This attenuation is particularly serious. Studies have shown that using a specific light source in advance to irradiate and anneal the battery sheet under certain temperature conditions will effectively prevent this attenuation phenomenon from occurring. However, there is currently no equipment dedicated to irradiation annealing of solar cells. [0003] For this reason, the applicant invented a roller-type solar cell radiation an...
