The production of photovoltaic energy does not produce any radiation.
Photovoltaic power generation is a technology that uses solar energy to convert light energy into electrical energy. It does not produce nuclear radiation or electromagnetic radiation. In the process of photovoltaic power generation, solar energy is absorbed and converted into electrical energy. This process does not require any chemical or nuclear reactions, so there are no environmental concerns such as the presence of radioactive waste in nuclear power plants or other energy facilities.
In addition, the surface of photovoltaic panels should be cleaned regularly to maintain solar energy absorption efficiency, but no radiation will be generated during the cleaning process. Although the solar spectrum contains electromagnetic waves such as ultraviolet lighte and visible, compared to other energy industries, photovoltaic energy production does not cause any harm to the human body. Photovoltaic power generation has the characteristics of safety and environmental protection and is an excellent source of clean energy.
The principle of photovoltaic energy production:
The principle of photovoltaic energy production is based on the photoelectric effect. In the photoelectric effect, when photons (i.e. sunlight) collide with a semiconductor material, they excite the semiconductor's electrons, resulting in separation and flow of charges.
Specifically, the photovoltaic power generation system consists of photovoltaic panels, panel supports, inverters, power grids, etc. Photovoltaic panels are generally made of semiconductor materials suchthan silicon, and their surface is divided into several small pieces to form a unit. Each unit absorbs photons from sunlight, converts them into electrons and creates an electric current in the semiconductor.
These units connect the current via metal clips to form the current output of the entire photovoltaic panel. When sunlight hits the photovoltaic panels, a direct current is generated. Under the action of the inverter, direct current is converted into alternating current to be transported and used in the electricity network.
