Q:Is there anyone who knows how to choose a good glue
General epoxy resin structural adhesive, fully cured is 24 hours, the purpose of the product to achieve the best bonding strength. The curing time is shortened according to the curing accelerator of epoxy resin. The general market is the fastest solid 5 minutes, you can play a positioning effect. Does not affect operation.
Q:How to calculate the conversion efficiency of monocrystalline silicon
Solar cell efficiency = (open circuit voltage * short-circuit voltage * fill factor) / (battery area * light amplitude) *100%Light intensity - AM1.5 as the standard, that is 1000W/m2Proportion of dark current - Irev>6 cell ratioThe proportion of low efficiency tablets - the proportion of P156Eff<14.5% batteries
Q:Why integrated circuits can be etched on silicon
First of all, the general circuit of the insulator, just a carrier, it plays the role of support and insulation. As for the integrated circuit, the bottom layer is called the substrate (generally P type semiconductor), is to participate in the work of integrated circuits. CMOS process, so the Nmos substrate are connected together, are the same substrate.Another image, that is, the integrated circuit is a combination of some electronic components and wiring, no insulation and insulation as a support. It is achieved by adding bias and other techniques to isolate.
Q:What is the role of silicon wafer annealing furnace, what specific requirements
I want to be the temperature to more than 1 thousand degrees, and then clean the furnace
Q:How to extract silicon from silicon wafers
Annealing: double position hot oxidation furnace after nitrogen purging, infrared heating to 300~500 DEG C, silicon wafer surface and oxygen react, so that the surface of silicon dioxide protection layer.
Q:How to make monocrystalline silicon solar cells
Diffusion bondingSolar cells require a large area of PN junction to achieve the conversion of light energy to electrical energy, while the diffusion furnace is a special equipment for manufacturing solar cell PN junction. Tube type diffusion furnace is mainly composed of quartz boat download four parts part, gas chamber, a furnace body part and a holder part etc.. Generally, the liquid source of three phosphorus oxychloride is used as the diffusion source. The P type silicon wafer is placed in a quartz tube of a tube type diffusion furnace, and three nitrogen oxychloride is used in the quartz vessel at the temperature of 850---900 degrees Celsius, and the phosphorus atom is obtained through the reaction of the phosphorus oxychloride and the silicon wafer through the reaction of the phosphorus and the phosphorus. After a certain time, the phosphorus atom from the surrounding surface layer into a silicon wafer, and wafer to internal diffusion through the void between the silicon atoms, forming a N type semiconductor and P type semiconductor interface, namely PN junction. The PN junction made by this method has good uniformity, the uniformity of box resistance is less than ten percent, and the lifetime of less than 10ms. The manufacture of PN junction is the most basic and most important process in the production of solar cells. Because it is the formation of PN junction, so that the electrons and holes in the flow is no longer back to the original place, so that the formation of the current, using the wire will lead to the current, dc.
Q:What is the specific way to clean the silicon wafer suede concrete steps
LED epitaxial wafer process:Over the past decade, in order to develop high brightness blue light-emitting diode, all over the world, the relevant research personnel are fully invested. The commercialization of products such as blue and green light-emitting diode two LED and laser diode LD application of the - III - V elements of the potential. In the current commercial LED materials and technology extension, red and green light emitting diodes are mainly epitaxy growth method of liquid phase epitaxy, and yellow, orange light emitting diode is still in vapor phase epitaxial growth method to grow P GaAs GaAsP materials.In general, the growth of GaN requires a very high temperature to interrupt the NH3 of the N-H solution, on the other hand, the kinetic simulation also learned that NH3 and MO Gas will react to produce no volatile by-products.
Q:How to do on the silicon wafer
1, observation and analysisFirst check the pollution level of the battery plate to be cleaned before cleaning. If it is mild pollution - no particles, only dust. It is recommended that we do the washing and scrubbing alone. This will not only save, save manpower and material resources, but also to extend the surface of the battery board to maintain a certain degree of brightness. Increase its life!
Q:What is the meaning of the wafer (100), the crystal orientation index or the crystal plane index
The coordinate system is set up in the crystal cellIs the coordinate of the direction vector
Q:Development trend of monocrystalline silicon wafer
LDK LDK is committed to the development of a solar polysilicon materials, ingots and silicon chip R & D, production, sales as one of the world's leading PV enterprises". In the field of polysilicon, polysilicon LDK LDK project to establish a closed-loop circulation system of the most advanced production technology, and all components of waste will be recycled, not only cost savings, but also protect the environment, to solve the biggest bottleneck in polysilicon production technology. After the project is put into production, the cost control will be far beyond the current level of production in China to reach the international advanced level. This will be China's most promising in the environment, scale, cost, quality and other aspects of the overall success of the silicon material project. By 2009, LDK LDK is expected to become the world's leading production capacity of the largest, most technologically advanced, most environmentally friendly process of polysilicon and solar wafer production base. The first practical photovoltaic slicing machine was born in 1980s, it originated from the research and work of Dr. Charles Hauser. Dr. Charles Hauser is the founder of the Swiss HCT slicing system, which is now the predecessor of the application materials company PWS precision silicon wafer processing system division. These machines use a cutting line with a slurry to complete the cutting action. Today, the main structure of the silicon ingot and wafer cutting machine is still based on the original Charles Dr. Hauser machine, but the processing load and cutting speed has been significantly improved.
