FAQ:
Q:How can i get some sample?
A:Yes , if you want order ,sample is not a problem.
Q:How about your solar panel efficency?
A: Our product efficency around 17.25%~18.25%.
Q:What’s the certificate you have got?
A: we have overall product certificate of ISO9001/ISO14001/CE/TUV/UL
- Q: What is the harm of silicon chip into the fingers?
- It is also easy to cause other damage, if a small piece of debris along with the flow of blood to the heart, it is very dangerous
- Q: What is the purpose of an encapsulant in a solar silicon wafer?
- The purpose of an encapsulant in a solar silicon wafer is to protect the wafer from external environmental factors such as moisture, dust, and temperature variations, ensuring the longevity and efficiency of the solar cell. It acts as a barrier, preventing any damage or degradation to the wafer, and also enhances the overall performance of the solar module by providing optical properties like anti-reflection and light trapping.
- Q: How are solar silicon wafers protected from physical damage during manufacturing and transportation?
- Solar silicon wafers are protected from physical damage during manufacturing and transportation through various measures. Firstly, they are usually packaged and stored in specialized containers or boxes that provide cushioning and shock absorption to minimize the risk of breakage. Additionally, these containers are designed to keep the wafers safe from external impacts or pressure during transportation. Furthermore, the wafers themselves are often coated with a protective layer, such as a thin film or tape, to safeguard them from scratches, abrasions, or other physical damage. This protective coating acts as a barrier, shielding the delicate silicon wafers from potential harm. Overall, a combination of proper packaging, cushioning, and protective coatings ensures that solar silicon wafers remain intact and undamaged throughout the manufacturing and transportation processes.
- Q: How are solar silicon wafers cut from a silicon ingot?
- Solar silicon wafers are cut from a silicon ingot using a process called wafering. This involves several steps including slicing, lapping, and polishing. Initially, a diamond wire saw is used to slice the ingot into thin wafers. Then, the rough surfaces of the sliced wafers are lapped to remove any imperfections and achieve the desired thickness. Finally, the wafers undergo a polishing process to achieve a smooth and mirror-like surface, which is essential for efficient solar cell production.
- Q: What are the different wafer orientations used in solar silicon wafer production?
- The different wafer orientations used in solar silicon wafer production are mainly three: (1) the most commonly used orientation is the <100> orientation, where the crystal structure is aligned along the <100> crystallographic direction; (2) the <111> orientation, which has a different crystal structure alignment; and (3) the <110> orientation, which is less commonly used but still finds some applications in certain solar cell designs.
- Q: How is the reflectivity of a solar silicon wafer reduced?
- The reflectivity of a solar silicon wafer is reduced through the application of an anti-reflective coating. This coating consists of a thin layer of materials that help to minimize the amount of light reflected off the surface of the wafer, allowing for more efficient absorption of sunlight and increased energy conversion in solar cells.
- Q: What is the purpose of a junction box in a solar silicon wafer?
- The purpose of a junction box in a solar silicon wafer is to provide a secure and protected enclosure for the electrical connections of the solar cells. It helps to connect the individual solar cells together and allows for the efficient transfer of generated electricity from the cells to the external circuitry, such as inverters or batteries. Additionally, the junction box also serves as a safety feature by offering protection against environmental elements and potential electrical hazards.
- Q: How do solar silicon wafers contribute to the overall weight of a solar panel?
- Solar silicon wafers contribute significantly to the overall weight of a solar panel. These wafers are the primary material used to convert sunlight into electricity. Since solar panels consist of multiple layers of silicon wafers, they account for a substantial portion of the panel's weight. The thickness and number of wafers used determine the weight, and while efforts have been made to reduce their thickness to minimize weight, they remain a significant factor in determining the overall weight of a solar panel.
- Q: Can solar silicon wafers be used in solar-powered street lighting?
- Yes, solar silicon wafers can be used in solar-powered street lighting. These wafers are commonly used in the production of solar cells, which convert sunlight into electricity. Solar-powered street lighting systems utilize solar panels made with silicon wafers to generate electricity from the sun and power the street lights.
- Q: Can solar silicon wafers be used in other electronic devices?
- Yes, solar silicon wafers can be used in other electronic devices. While their primary use is in solar panels to convert sunlight into electricity, they can also be utilized in various electronic applications such as semiconductors, integrated circuits, and sensors.
