Description

A hollow component of a photovoltaic cell

technical field

The utility model relates to a hollow component of a photovoltaic cell.

Background technique

The hollow components of photovoltaic cells usually have a structure of glass-sealant film-solar silicon wafer-sealant film-glass-separator-hollow-glass, and a junction box is also provided. For the sake of beauty and to prevent the junction box from being damaged during use, The general practice is to install the junction box between the second layer of glass and the third layer of glass, and fill the sealant around it, so that the junction box is buried by the sealant, so as to achieve the effect of hiding the junction box inside the component frame. purpose, but this method leads to poor heat dissipation of the junction box, which may easily cause the temperature of the diode in the junction box to be too high or the temperature of the junction box itself to be too high, thereby causing the diode to fail and affecting the safety performance of the entire assembly.

Utility model content

The purpose of the utility model is to provide a hollow photovoltaic cell assembly, which can effectively solve the heat dissipation problem of the junction box in the assembly and improve the reliability and safety of the assembly.

The technical scheme adopted by the utility model to achieve its purpose is: a hollow module of photovoltaic cells, including outer glass, inner glass and laminated glass arranged between the outer glass and the inner glass, the outer glass and the laminated glass A solar silicon wafer is arranged between them, and the solar silicon wafer is bonded together with the outer glass and the laminated glass through a sealant film, and a hollow structure is formed between the laminated glass and the inner glass, and a spacer is provided. A junction box is arranged between the layer glass and the inner glass, and the junction box is filled with sealant, and a heat-conducting glue is arranged between the junction box and the spacer, and the junction box is connected with the spacer through the heat-conduction glue.

The beneficial effect of the utility model is that: the utility model uses heat-conducting glue to connect the shell of the junction box with the spacer in the assembly, thereby forming a heat dissipation channel of the diode-junction box shell-heat-conducting glue-spacer-component glass, so that The heat of the junction box can be dissipated through the spacer with larger heat capacity and the component glass, which effectively reduces the temperature of the junction box, reduces the risk of junction box and diode failure due to excessive temperature, and improves the reliability and reliability of the components. safety.
