Problems solved by technology

At present, the recycling of photovoltaic modules is directly buried. This method seems to solve the problem of recycling photovoltaic modules. However, the Pb metal in the buried photovoltaic modules will cause land pollution, and this recycling method will also cause material pollution. Another method of recycling photovoltaic modules is

Abstract

The invention discloses a method for recycling a photovoltaic module, which starts from the source of the photovoltaic module, and sequentially strips an outer frame, a TPT film layer, an EVA film layer, a battery string, another EVA film layer and glass from the photovoltaic module by detaching the structure of the photovoltaic module, separates the battery string, and completes the recycling ofthe battery string. According to the method for recycling the photovoltaic module, not only solar cells can be recycled, the glass can also be recycled, and meanwhile, soil and environment pollution caused by harmful metal Pb and environment pollution caused by plastic of the TPT film layer and the EVA film layer are avoided.

Description

technical field [0001] The invention relates to the technical field of photovoltaic components, in particular to a method for recycling photovoltaic components. Background technique [0002] Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. [0003] As a renewable energy photovoltaic module, if it is not properly treated after the conference, it will be considered the biggest shortcoming of the photovoltaic module. From the perspective of the composition of the photovoltaic module, it includes precious metal Ag, Au and harmful metal Pb, etc., and the purity of these metals is very high. Relatively high, can reach 99.9%, direct burial will cause environmental pollution. At present, the recycling of photovoltaic modules is directly buried. This method seems to solve the problem of recycling photovoltaic modules. However, the Pb metal in the buried photovoltai...
