Problems solved by technology

[0003] It has been nearly 20 years since crystalline silicon solar panels have been used for a long time. With the expiration of product life, a large number of waste components need to be recycled. It is feasible to disassemble and recycle crystalline silicon cells from waste components. Processing direction; the existing pyrolysis technology can realize large-scale recycling and repair of crystalline silicon solar panels, but during the pyrolysis process, most of the solder strips connected to the main grid of the battery electrodes will fall off, causing most of the main grid of the battery electrodes to be dislodged. If it falls off, it is impossible to use the conventional soldering strip or probe method to form a good contact with the external circuit; at the same time, the crystalline silicon solar cells that have been used for a long time and pyrolysis treatment generally have performance attenuation due to the increase and accumulation of defects in the silicon material itself.

Abstract

The invention discloses a crystalline silicon solar battery panel repairing treatment device and a method for using the same, which can realize heat treatment and voltage application on the crystalline silicon solar battery panel, and avoid the failure of external connection and power supply due to the absence of the main grid of the battery. The device includes a hot liquid tank , stage, conductive metal film, flexible metal film contact will not cause any damage to the electrode surface; using flexible insulating film and liquid pressure, the pressure is evenly distributed on the surface of the crystalline silicon solar panel, the pressure is regulated by the weight of the liquid, and there is no stress The problem of concentration; the conductive metal film contacts the fine grid and the main grid of the entire front battery, and the current does not need to pass through the main grid, and then to the fine grid, so as to avoid the danger of local heating of the battery due to excessive current concentration or breakdown caused by excessive current; high heat The battery is heated by the hot liquid in the capacity. Compared with heating with a heating plate, the temperature stability and uniformity are better.

Description

technical field [0001] The invention relates to the field of solar battery panels, in particular to a repairing treatment device for a crystalline silicon solar battery panel and a method for using the same. Background technique [0002] Crystalline silicon solar cells are currently the mainstream product in the photovoltaic market. In 2018, the global output reached 115GW, and the domestic output reached 65GW. [0003] It has been nearly 20 years since crystalline silicon solar panels have been used for a long time. With the expiration of product life, a large number of waste components need to be recycled. It is feasible to disassemble and recycle crystalline silicon cells from waste components. Processing direction; the existing pyrolysis technology can realize large-scale recycling and repair of crystalline silicon solar panels, but during the pyrolysis process, most of the solder strips connected to the main grid of the battery electrodes will fall off, causing most of ...
