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 purity requirement for solar silicon wafers?
- The purity requirement for solar silicon wafers is extremely high, with a generally accepted standard of at least 99.9999% purity, or 6N purity. This level of purity ensures minimal impurities and defects in the silicon, maximizing the efficiency and performance of solar cells.
- Q: How are solar silicon wafers affected by surface recombination velocity?
- Solar silicon wafers are significantly affected by surface recombination velocity. High surface recombination velocities can lead to the loss of majority carriers near the surface, reducing the efficiency of solar cells. This results in a decrease in the overall conversion of sunlight into electricity. Therefore, minimizing surface recombination velocity is crucial to enhance the performance of solar silicon wafers and improve the efficiency of solar cells.
- Q: How do solar silicon wafers perform in cold climates?
- Solar silicon wafers typically perform well in cold climates, as lower temperatures can actually increase their efficiency. Unlike some other types of solar panels, silicon-based panels are less sensitive to temperature variations, which allows them to maintain a relatively stable output in cold weather. Additionally, snow can actually help improve solar panel performance by reflecting sunlight onto the panels. However, it is important to note that excessive snow cover or ice buildup on the panels can temporarily reduce their efficiency until they are cleared or thawed.
- Q: What can be used to adjust its viscosity
- Polyethylene glycol and water soluble, I believe this may help you solve the problem
- Q: What is the cost of a solar silicon wafer?
- The cost of a solar silicon wafer can vary depending on various factors such as size, quality, and market conditions. On average, the cost of a standard silicon wafer used in solar panels ranges from $0.10 to $0.30 per watt. However, it is important to note that prices may fluctuate due to factors like supply and demand, technological advancements, and economies of scale.
- Q: Are there any alternatives to using solar silicon wafers in solar cells?
- Yes, there are several alternatives to using solar silicon wafers in solar cells. Some of these alternatives include thin-film solar cells made from materials such as cadmium telluride (CdTe), copper indium gallium selenide (CIGS), and organic photovoltaic materials. These alternative materials offer advantages such as lower manufacturing costs, flexibility, and higher energy conversion efficiencies. However, each alternative has its own set of limitations and challenges that need to be addressed for widespread adoption.
- Q: How are solar silicon wafers affected by photon recycling?
- Solar silicon wafers are positively affected by photon recycling as it allows for the reabsorption and redirection of unused photons within the solar cell, increasing overall efficiency.
- Q: How are solar silicon wafers tested for mechanical strength and durability?
- Solar silicon wafers are typically tested for mechanical strength and durability through various methods. One common approach is the four-point bending test, where a wafer is subjected to controlled bending stress to measure its flexural strength and resistance to breakage. Another method involves the use of a diamond-tipped stylus to scratch the wafer's surface and evaluate its hardness. Additionally, tests like the ball drop test or impact test are conducted to simulate real-life scenarios and assess the wafer's resistance to mechanical shocks. These tests help ensure that solar silicon wafers can withstand the rigors of manufacturing, installation, and long-term operation in solar panels.
- Q: Can solar silicon wafers be used in agricultural irrigation systems?
- Yes, solar silicon wafers can be used in agricultural irrigation systems. They can be utilized to power solar panels that generate electricity, which can then be used to run pumps and other equipment needed for irrigation.
- Q: Below what the photovoltaic industry specific industry classification, solar silicon manufacturing enterprises, mainly engaged in single and polycrystalline silicon, polycrystalline silicon wafer cutting casting, single enterprise, what are the concrete classification, a solar silicon slice of this industry?
- Photovoltaic involves a lot, but the company makes silicon chips in terms of, so if the use of photovoltaic culvert cover, too general, I need a detailed classification of the industry, and then go to the specific industry analysis
