Hello, i'm here today to answer your questions. The solar panel works, the solar panel works, and many of the partners don't know it yet. Now let's see
1. Solar cell power generation: solar cells are devices that respond to a pair of light and can convert light energy into electricity。
2. There are a number of types of materials that can produce photo-voltaic effects, such as single crystal silicon, polycrystal silicon, non-crystal silicon, arsenic, copper, etc。
3. Their power generation rationale is essentially the same and the photogeneration process is described as a crystal。
4-p crystalline silicon is available for n-silicate via absynthetic phosphorus, forming a p-n knot。
5. When the light is irradiated to the surface of the solar cell, a portion of the photons is absorbed by silicon materials; the energy of the photons is passed to the silicon atoms, causing the electrons to move away and become free electrons, which aggregate on both sides of the p-n knot, into a difference in the level of power, and when the outside circuit is connected, there will be a current flow through the outside circuit to produce some output power。
6. The essence of this process is the process of conversion of photo-energy to electricity。
7 - the manufacture of crystalline silicon solar cells: silicon is one of the most abundant materials on our planet。
Since the 19th century scientists discovered the semiconductor properties of crystal silicon, it has changed almost everything, even human thinking。
At the end of the twentieth century, there were images and effects of silicon in our lives, and crystalline silicon solar cells were the fastest industrialized in almost 15 years。
The production process can be broadly divided into five steps: a, the purification processb, the lifting processc, the slice processd, the battery processe, and the containment process。
Application of solar cells: in the 1960s, scientists had applied solar cells to space technology-- • the power of communications satellites, which, at the end of the last century, in the course of human self-reflection, has become more and more friendly to such a clean and direct form of energy as photovoltaic power, not only in space applications but also in many fields。
12 for example: solar courtlights, solar power household systems, independent systems of village power supply, photovoltaic pumps (water or irrigation), communications power supply, protection of the cathode of the oil pipeline, cable communications station power supply, desalination systems, urban midway signs, highway signs, etc。
Advanced countries, such as europe and the united states, have integrated photovoltaic power into urban power systems and natural village power systems in remote areas。
The integration of solar batteries with construction systems has developed an industrial trend。
This paper is shared here, and i hope the young people will like it。
