Photovoltaic System

Solar cells use sunlight to generate electricity. As long as the sun shines on the battery, it will continue to generate electricity. It is a clean energy with the advantages of safety, reliability, no noise and no consumption of raw materials. It has the advantages of great convenience for residents in remote areas. So what is the working principle of solar energy? Today we'll explore it. Solar cell is a device that directly converts light into electric energy through photochemical effect. When sunlight shines on the semiconductor pn junction, a new hole (electron pair) is formed. Under the action of the electric field, the hole flows from the N region to the p region, and the electron flows from the p region to the N region. After the circuit is connected, a current is formed to convert light energy into electric energy.Solar panel, also known as solar cell module, is a kind of photoelectric semiconductor sheet that uses sunlight to directly generate electricity. It is an assembly composed of several solar cells assembled on a plate in a certain way. It is the core part of the solar power generation system.The earth, the green home for human survival.
With the development of human civilization, it has gradually become a victim of economic growth. Clean energy is imminent.
The sun concentrates 99.87 percent of the mass of the solar system, and one twenty-two percent of the energy radiates to the earth, becoming the main source of photosynthetic heat on the earth. Solar energy is one of the cleanest, most lasting and most magical energy of all.
