[0002] Photovoltaic cells are devices that use the radiation energy of sunlight to convert it into electrical energy. They are mainly composed of two parts: one is the solar panel and the other is the controller. The solar panel is a board made of semiconductor material with a thin layer of PVD (physical vapor deposition) film on it. The function of the PVD film is to focus the energy in the sunlight on the surface of the panel to generate current.
