[0002] Photovoltaic modules, as the core components of solar power generation systems, play an important role in converting sunlight into electrical energy. They are usually composed of multiple photovoltaic cell units. These cell units use the photovoltaic effect to generate direct current under sunlight. Photovoltaic modules are not only efficient, environmentally friendly, and renewable, but also adaptable to various complex environments. They are widely used in many fields such as households, industry, and agriculture. In the power generation process, the electricity generated by photovoltaic modules can be directly supplied to the load, or converted into alternating current through an inverter and connected to the power grid. In addition, photovoltaic modules also have the advantages of long life and low maintenance costs. They can generate electricity continuously and stably for more than 25 years. In short, photovoltaic modules are an indispensable and important component in solar power generation systems, with broad application prospects and huge development potential.

[0003] In the existing technology, traditional photovoltaic modules are mainly composed of photovoltaic cells, glass cover plates, EVA films, back plates, frames and junction boxes. The cells are responsible for absorbing sunlight and converting it into electrical energy, while other components play the role of protection, sealing and conduction.

[0004] However, traditional photovoltaic modules will generate a lot of heat when in use, and this heat will be lost to the outside, which causes a decrease in energy conversion efficiency. This heat loss not only reduces the overall efficiency of the system, but may also cause the temperature of the module to rise, affecting the performance of the battery material, and in the long run accelerating the aging of the module and shortening its service life. For this reason, the utility model proposes a photovoltaic module with waste heat recovery function to solve the above-mentioned technical problems. Utility Model Content
