- Q: Are solar silicon wafers susceptible to cracking?
- Yes, solar silicon wafers are susceptible to cracking.
- Q: I work in a solar cell company, do silicon chip testing on the human body what chronic harm?
- If it is at least module, such as CVD PVD, there are some toxic gases
- Q: The higher the resistivity of silicon wafers, the better?!!! 1 experts please answer me!
- Low resistivity is helpful to improve the opening pressure, high resistivity and help to improve the short-circuit current, the best match between the two is about 1 -3! Own understanding!
- Q: What are the main challenges in manufacturing solar silicon wafers?
- The main challenges in manufacturing solar silicon wafers include high production costs, energy-intensive processes, and the need for high purity silicon. Additionally, the industry faces challenges in developing efficient methods for recycling and reducing waste during the manufacturing process.
- Q: How does the efficiency of a solar silicon wafer change with temperature?
- The efficiency of a solar silicon wafer typically decreases with increasing temperature. This is because the electrical conductivity of silicon increases with temperature, leading to higher recombination rates and reduced electron-hole collection efficiency. Additionally, higher temperatures can cause an increase in the bandgap, resulting in a decrease in the number of photons absorbed by the wafer. These factors contribute to a decrease in the overall efficiency of the solar silicon wafer as temperature rises.
- Q: What is the typical doping material used in solar silicon wafers?
- The typical doping material used in solar silicon wafers is usually boron for p-type doping and phosphorus for n-type doping.
- Q: How are solar silicon wafers protected against corrosion?
- Solar silicon wafers are protected against corrosion through the application of various protective coatings and encapsulation materials. These coatings act as a barrier, preventing moisture, oxygen, and other corrosive elements from reaching the silicon surface. Additionally, the wafers are often encapsulated within a durable and weather-resistant material, such as glass or polymer, which provides an additional layer of protection against corrosion.
- Q: What is the typical efficiency range of solar silicon wafers?
- The typical efficiency range of solar silicon wafers is between 15% to 22%.
- Q: After wafer cleaning, how to change the film?
- Name compositionEffectSPMH2SO4: H2O2: H2ORemoval of heavy organic matter, but it is difficult to remove organic matter when it is very seriousDHFHF: (H2O2): H2OCorrosion of the surface oxide layer to remove metal contaminationAPM (SC1) NH4OH: H2O2: H2O can remove particles, some organic matter and some metals, this solution will increase the surface roughness of silicon waferHPM (SC2) HCl: (H2O2): H2O is mainly used to remove metal contamination
- Q: What is the maximum voltage a solar silicon wafer can handle?
- The maximum voltage a solar silicon wafer can handle typically depends on various factors, such as the wafer's thickness, quality, and design. However, most standard solar silicon wafers can handle voltages ranging from 600 to 1000 volts. It is important to note that exceeding the maximum voltage limit can potentially damage the wafer and affect its performance.
