Silicon wafer cutting machine is also known as silicon wafer laser cutting machine and laser cutting machine. This is another new application of laser cutting machine in cutting silicon substrates in electronics industry. Laser scribing uses a high-energy laser beam to irradiate the surface of the workpiece to locally melt and vaporize the irradiated area, thereby achieving the purpose of scribing. Since the laser is focused by a special optical system on a very small light point with high energy density, its processing takes place without contact, there is no mechanical stamping force on the part itself and the part is not easily deformed. It has minimal thermal impact and high marking accuracy, and is widely used for cutting and scribing solar panels and thin metal sheets.
1. A solar panel can continueto be used after being cut.
First, depending on the specific application area, some special products do not require much power generation, so they need to be cut and then assembled according to the appropriate specifications.
The second consists of; improve the utilization rate of raw materials. Solar cells are thin sheets that are extremely fragile. During the production process, it is inevitable that some products will have defects such as missing corners, cracks and skipped edges due to various reasons. not completely waste. Some pieces are still valuable.
As for the cutting size, it is based on the needs of the actual product. It mainly depends on parameters such as power, voltage, current area and shape of the electrode.
2. Solar panels and simple solar cells cannot be used directlyent as sources of energy. To realize a power supply, several individual cells must be connected in series, in parallel and tightly sealed within the components. Solar panels (also called solar cell modules) are the essential part of the solar power generation system and the most important part of the solar power generation system.
3. Solar cells are devices that respond to light and can convert light energy into electricity. There are many types of materials that can produce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, copper selenium indium, etc. Their principles of energy production are basically the same. Now, a crystal is used as an example to describe the photovoltaic energy production process. Crystalline siliconP-type can be doped with phosphorus to obtain N-type silicon, forming a PN junction.
When light irradiates the surface of the solar cell, part of the photons is absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the electrons to migrate and become free electrons which gather on both sides of the P-N junction to form With the potential difference, when the external circuit is connected, under the Under the action of this voltage, a current will flow through the external circuit to produce a certain output power. The essence of this process is: the process of converting photon energy into electrical energy.
