Photovoltaic panels refer to devices that directly convert solar energy into electrical energy by using the photovoltaic effect of semiconductor materials under light conditions. It is the most direct way to use solar energy. Most of the materials of photovoltaic panels are silicon. Power can be generated where there is sunlight, so solar photovoltaic power generation by photovoltaic panels is suitable for a variety of occasions, from large power stations to small portable chargers. However, although the reserves of solar energy are very large, the proportion of electricity produced by mankind using solar energy in the total global energy consumption is still quite small, only about 0.16%. Therefore, actively developing low-cost and high-efficiency photovoltaic panel materials and increasing the photoelectric conversion rate will help solve the world's energy and environmental crisis, and have very great use-value and practical significance. So what is the classification of photovoltaic panels? Let's take a look together next.
Here is the content list:
Single crystal of photovoltaic panel silicon
Monocrystalline silicon for photovoltaic panels is mainly used to make semiconductor components
The single crystal of silicon of the photovoltaic panel has a substantially complete lattice structure crystal. Photovoltaic panels have different properties in different directions and are a good semiconducting material. The purity is required to reach 99.9999% or even more than 99.9999999%. Used in the manufacture of semiconductor devices, photovoltaic panels, etc. Photovoltaic panels are made of high-purity polycrystalline silicon drawn in a single crystal furnace.
When the molten photovoltaic panel elemental silicon is solidified, the silicon atoms are arranged in a diamond lattice into many crystal nuclei. If these photovoltaic panel nuclei grow into crystal grains with the same crystal plane orientation, these crystal grains will be combined in parallel to crystallize into a photovoltaic panel single Crystalline silicon. Photovoltaic panel monocrystalline silicon has the physical properties of a metalloid and has weak electrical conductivity. The electrical conductivity of photovoltaic panels increases with the rise of temperature and has significant semi-conductivity. Ultra-pure photovoltaic panel monocrystalline silicon is an intrinsic semiconductor. Doping a small amount of IIIA group elements such as boron into the ultra-pure photovoltaic panel monocrystalline silicon can increase its conductivity and form a p-type photovoltaic panel silicon semiconductor. As doping with trace amounts of VA elements, such as phosphorus or arsenic, can also increase the degree of conductivity and form an n-type silicon semiconductor. The production method of photovoltaic panel monocrystalline silicon is usually to make polycrystalline silicon or amorphous silicon first and then use the Czochralski method or floating zone melting method to grow rod-shaped photovoltaic panel monocrystalline silicon from the melt.
Uses: Monocrystalline silicon for photovoltaic panels is the raw material for manufacturing semiconductor silicon devices. Monocrystalline silicon for photovoltaic panels is used to make high-power rectifiers, high-power transistors, diodes, switching devices, etc.
Monocrystalline silicon for photovoltaic panels is a relatively active non-metallic element. Monocrystalline silicon for photovoltaic panels is an important part of crystalline materials and is at the forefront of the development of new materials. Its main purpose is to be used as a semiconductor material and the use of photovoltaic panels, solar photovoltaic power generation, heating, etc. Because solar energy has many advantages such as cleanliness, environmental protection, and convenience, in the past 30 years, solar energy utilization technology has achieved rapid development in research and development, commercial production, and market development, and has become one of the world's fast and stable emerging industries.
