Problems solved by technology

Due to the high conversion efficiency of cadmium telluride batteries and the large current and voltage, the junction boxes of traditional crystalline silicon solar cells and amorphous silicon solar cells are not suitable for cadmium telluride batteries, and the traditional junction boxes have a large space and are difficult to fill. The amount of glue is large and the heat dissipation effect is poor, which cannot meet the needs of cadmium telluride thin film batteries, thus limiting its scope of application

Abstract

The invention discloses a junction box for a cadmium telluride film module. The junction box comprises a junction box body (14) and a junction box cover (11); a heat-conducting glue pipe (5), glue filling cavities, a positive electrode component, a negative electrode component and a diode (4) are arranged in the junction box body (14), the glue filling cavities are formed in the two sides of the heat-conducting glue pipe (5), and the two ends of the diode (4) are connected with the positive electrode component and the negative electrode component respectively. According to the junction box forthe cadmium telluride film module, the good effect of reducing the glue filling amount to prevent short-circuiting is achieved by additionally arranging the heat-conducting glue pipe (5); meanwhile,the good heat dissipation effect of the device is improved, and the application range of the device is expanded.

Description

technical field [0001] The invention relates to the matching field of cadmium telluride thin film components, in particular to a junction box for cadmium telluride thin film components. Background technique [0002] Photovoltaic junction box is a connector between the solar cell array formed by solar cell modules and the solar charging control device. It is very important in the composition of solar modules, and its main function is to connect the power generated by solar cells with external lines. Therefore, the selection of solar cell module junction box is very important. The main information for the selection of photovoltaic junction box should be the maximum current and short-circuit current of the module. Due to the high conversion efficiency of cadmium telluride batteries and the large current and voltage, the junction boxes of traditional crystalline silicon solar cells and amorphous silicon solar cells are not suitable for cadmium telluride batteries, and the tradit...
