How LED streetlight manufacturers use solar photovoltaic effects to make solar streetlights
LED street light manufacturersThe production of solar street lights is utilized The solar cell made by the principle of photovoltaic effect receives the solar radiation energy and converts it into electric energy output. The photovoltaic effect refers to the phenomenon that the semiconductor generates electromotive force when it is irradiated with light.
The photovoltaic effect is referred to as the photovoltaic effect, and the wind-solar complementary controller refers to a phenomenon in which a light causes a potential difference between a heterogeneous semiconductor or a different portion where a semiconductor and a metal are combined. It is first the process of converting photons (light waves) into electrons and converting light energy into electrical energy; secondly, it is the process of forming voltage. With voltage, it is like building a dam. If the two are connected, a circuit of current will be formed.
If the light is shining on the solar cell and the light is absorbed in the interface layer, it has enough energy Photons are capable of exciting electrons from covalent bonds in P-type silicon and N-type silicon, resulting in electron-hole pairs. The electrons and holes near the interface layer are separated from each other by the electric field action of the space charge before recombination. The electrons move toward the positively charged N region and the holes toward the negatively charged P region. An outwardly testable voltage is generated between the P and N regions by charge separation of the interface layer. At this point, electrodes can be placed on both sides of the silicon and connected to the voltmeter. For crystalline silicon solar cells, the typical value of the open circuit voltage is 0.5 to 0.6V. The more electron-hole pairs that are produced by the illumination at the interface layer, the greater the current. The more light energy absorbed by the interface layer, the larger the cell area of the interface layer, and the greater the current formed in the solar cell.
Solar energy is the cleanest, safer and more reliable energy source in the future. The opportunities for LED street lamp manufacturers cannot be missed. Developed countries are taking the development and utilization of solar energy as the main content of the energy revolution. Langxu Lighting is a well-known Yangzhou street lamp manufacturer and Yangzhou high pole lamp manufacturer. It has a certain reputation in the industry. Welcome to purchase.
