Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a method for preparing a photovoltaic cell module. The present invention also relates to a photovoltaic cell assembly produced by the above method for preparing the photovoltaic cell assembly. Background technique [0002] Solar photovoltaic cells, referred to as photovoltaic cells, are used to directly convert the sun's light energy into electrical energy. Compared with conventional energy sources, photovoltaic cells are a renewable and clean energy source, which is beneficial to environmental protection and can save expensive transmission lines, so photovoltaic cells have broad application prospects. [0003] Solar photovoltaic cell components usually include photovoltaic cells, substrates and transparent material layers. Photovoltaic cells are used to absorb solar energy and convert solar energy into electrical energy for storage; the substrate has a ce...

Problems solved by technology

[0006] The above-mentioned solar photovoltaic cell module preparation method needs to rely on huge processing equipment in the packaging process, and the process is relatively complicated, especially for low-power photovoltaic solar cell modules, the cost is relatively high; Volatile, it is easy to cause environmental pollution; because the epoxy packaging relies on the leveling of the resin glue, the production of the product basically relies on manual operations, and the thickness of the glue is not easy to grasp. In some places, the thickness of the glue is thicker, resulting in the The transparency of the place is low; at the same time, this method is limited to the production of planar solar photovoltaic cell components, not for special-shaped solar photovoltaic cell components, and the scope of application is narrow

[0007] In addition, the working environment of the solar photovoltaic cell module encapsulated by resin drop glue can only be between -5°C and 40°C, the weather resistance is poor, it is prone to yellowing and falling off, and its life span is only about 5 years, which is different from that of photovoltaic cells. Long life does not match, resulting in a certain degree of waste
