- Q:Why silicon wafers are made in watts!
- Crystalline silicon photovoltaic cells have two types of monocrystalline silicon and polycrystalline silicon, with P (or n) silicon substrate, through the formation of phosphorus (or boron) diffusion Pn formation, production technology is mature, is the leading product in the photovoltaic market. The buried layer electrode, surface passivation, enhanced light trapping, dense grid technology, optimization of back electrode and contact electrode technology, improve the collection efficiency of carrier materials, optimization of anti elbow membrane, concave convex surface, high reflective back electrode, the photoelectric conversion efficiency is greatly improved. Silicon photocell area is limited, the larger the phi 10 to 20cm wafer, the annual production capacity of 46MW/a. At present, the main task is to continue to expand the scale of the industry, the development of ribbon silicon photovoltaic technology, improve material utilization. Internationally recognized as the highest efficiency under AM1.5 conditions of 24%, the space with high quality efficiency in the AMO condition is about 13.5 - 18% of the ground with a large number of production in the AM1 conditions in the more than 11 - 18%. It can reduce the cost, but the efficiency is lower, which is made by the method of directional solidification. Optimization of the silver electrode and aluminum paste screen printing, grinding and polishing process, do everything possible to further reduce costs, improve efficiency, the maximum conversion efficiency of polycrystalline silicon photovoltaic cells up to 18.6%.
- Q:One hundred watts of solar panels to how many pieces of silicon wafers, 156 of single crystals and polycrystalline
- Whereas it is high. If we do not consider the area, the same power, the electricity generated is the same, with high conversion rate and low exchange rate independent of all aspects of life, of course, there will be some impact. So I do not know clearly? I is a professional manufacturer of solar photovoltaic, do not understand what I can find. If you can.
- Q:How much is the thickness of the silicon wafer
- And two knives. We do DIP package, 4 inch wafer to thin to 0.300mm; 6 inch wafer to be reduced to about 0.320mm, error 0.020mm.
- Q:What is a good solar wafer testing equipment?
- PL-- detection of micro cracks, black spots, black and other issuesWafer sorting - Detection AOI, PN, resistivity, thickness, lifetime, stria depth
- Q:What is a silicon wafer for unidirectional and bidirectional cutting? What is the difference between the two?
- One way and two way cutting of silicon wafer is the two way to cut silicon ingot by using solar energy cutting wire.When slicing machine uses solar cutting line to cut silicon ingot,
- 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:Who is the best silicon chip dryer?
- Silicon wafer drying machine is the Wuxi automation technology to do, that is, before the design of the Song Jiang Yang, now is an upgraded version of the. Easy to use.
- Q:What are the raw materials of silicon wafers
- As a variable current switch, the transistor can control the output current based on the input voltage. Different from the common mechanical switch (such as Relay, switch), the transistor uses the electrical signal to control the opening and closing, and the switching speed can be very fast, the switching speed of the laboratory can reach more than 100GHz.
- Q:How many times is the resistance of the same size silicon
- Silicon is one of the largest and most widely used semiconductor materials, and its output and consumption mark the level of a country's electronics industry.
- Q:How do we use the scanning electron microscope
- After wiping with cotton wool, wash ear ball can be dried.Some of the words can be placed in alcohol solution ultrasonic cleaning, the effect is almost.
