Grade A 156x156mm Poly Stable Quality Solar Cell
Solar Module Summarize
Solar Module is the core part of solar PV power systems,also is the highest value part of it. The function of Solor Module is to convert the sun's radiation to electrical energy, or transfer it to battery and store in it, or to drive the load running.
The Product has been widely used in space and ground, it mainly used for power generation systems, charging systems, road lighting and traffic signs areas. It could offer a wide range of power and voltage, and with high conversion efficiency, and long service life.

- Q:The purpose and means of chemical etching of silicon wafers?
- After slicing and grinding, the surface of silicon wafer has a layer of damage and pollution due to processing stress
- Q:The production of silicon units do front-line production workers harmful to the body
- The two stage is the most important process of production silicon ingot and slicing stage in the production process, GT ingot furnace and HCT slicing machine are relatively closed production, metallurgy, nonferrous metal, chemical industry, harm can be ignored
- Q:Ultrasonic cleaning cleaning silicon?
- 1, silicon wafer wafer ultrasonic cleaning function.2, cleaning the wafer production process, pollutants using ultrasonic cleaning machine effectively remove organic matter, wafer surface particles and metal impurities, natural oxide layer and quartz, plastic containers and accessories, the wafer surface damage characteristics. According to different cleaning process, the corresponding cleaning unit is equipped with independent control.
- Q:How is the wafer appearance caused? The performance of the chip half white, a class of black! Seek help！
- You should be the color difference problem is caused by the mortar temperature cutting room temperature and workshop temperature also influenced to reduce this effect only from the cleaning rod to minimize the time spent between, this is the enthusiasm of the staff problem
- Q:How to make monocrystalline silicon solar cells
- Wafer inspectionSilicon wafer is the carrier of solar cell, the quality of silicon wafer directly determines the conversion efficiency of solar cell. This procedure is mainly used to measure the technical parameters of silicon wafer on line. These parameters mainly include the surface roughness of the silicon wafer, the lifetime of the minority, the resistivity, the P/N type and the micro crack. The device is divided into four parts: automatic loading and unloading, silicon wafer transmission, system integration part and. The silicon photovoltaic detector on the silicon wafer surface roughness were detected, and the size and appearance of diagonal parameter detection chip; micro crack detection module is used to detect silicon micro cracks; another two detecting module, a [url=] module [/url] online test mainly test wafer resistivity and wafer type, on the other a module for lifetime test wafer. The detection of the diagonal and micro cracks of the silicon wafer is needed before the sub lifetime and resistivity measurement. Wafer inspection equipment can automatic loading and unloading, and substandard products in a fixed position, so as to improve the detection accuracy and efficiency.
- Q:Polished silicon wafers can be most SEM substrates
- A lot of nanotubes, wires and so on are grown on similar substrates, and then direct SEM observation.
- Q:After the velvet or the original silicon
- Sand cutting is the case, it is silicon cutting related issues,
- Q:What is the difference between silicon wafer P111 and P100
- If the crystal is body centered cubic lattice, the crystal orientation through the cube on the diagonal atoms
- Q:I grew Ag particles on a silicon wafer, about a few hundred nanometers in size
- Alcohol is usually placed inside, with ultrasonic cleaning instrument scattered about, the purpose is to make the particles do not reunite together.
- Q:What is the cutting fluid for solar wafer cutting?
- Because in the China multi wire cutting machine was first used in semiconductor cutting, so that only the Swiss MB and HCT, the Swiss system thinking line cutting machine with special emphasis on power and environmental protection, so that this kind of machine in the cutting process of mortar viscosity requirement is relatively high, the most direct embodiment is to use the cutting fluid is oily, reflected in the raw material cutting fluid is used to peg, otherwise, the power will be the formation of excess waste machine. NTC is the rise in the solar industry on the occasion, we seize the opportunity, to imitate the Swiss line cutting machine design and production, but the Swiss precision machine modified to virtually out of order, the rapid development of the pursuit of efficiency of solar wafer cutting industry, especially to the rise of China solar wafer cutting industry thus, China quickly occupied the market leader, the share reached 65%. However, the company has done a little better, although the power system and the power of the machine to reduce a lot, you can use the machine in the use of cutting fluid on the Swiss machine standards. Oily cutting fluid cutting efficiency and surface cut out of the film is generally better than the aqueous solution of cutting fluid, but the performance of Japanese light wire cutting machine, which he used oily fluid will cause a burden on his power, so Japanese developed this kind of water-based cutting fluid. Regardless of the cost or the use of the Japanese machine are more consistent, and easy to recycle. This NTC machine oil cutting fluid and water-based cutting fluid can be used.
