[0002] Photovoltaic panels are devices that use solar energy to convert light energy into electrical energy. They are composed of multiple solar cells that directly convert solar energy into electrical energy. The working principle of photovoltaic panels is based on the photoelectric effect, that is, when sunlight shines on the photovoltaic panel, photons interact with atoms in the semiconductor material, exciting electrons to jump from the valence band to the conduction band, thereby generating current. Photovoltaic panels have the advantages of being clean, renewable, and noiseless. They are widely used in rooftops, solar power stations and other fields, making important contributions to the development of sustainable energy. With the continuous advancement of technology, the efficiency of photovoltaic panels continues to increase and the cost continues to decrease. It is expected that they will become more popular and developed in the future.
