THE CHARACTERISTIC OF 156P POLY-SILICON SOLAR CELLS

1.Format 156mm×156mm±0.5mm,Thickness 210μm±30μm.
     2.High efficiency in photovoltaic conversion 16.3%~17.93%;  
     3.Low inverse current, high shunt resistance and high dependability.
     4.Front(-): covered by dark blue silicon nitride anti-reflecting coating(silicon nitride) with bus bars(silver), 2/3/5 bud bars(silver).
     5.Back(+): wide soldering pads(silver), back surface field(aluminum),high quality paste for the BSF and the electrode ensure higher tension and improve soldering easiness.

Q:What is the role of anti-reflective coatings on solar cells?
The role of anti-reflective coatings on solar cells is to reduce the amount of light reflection and increase the amount of light absorption by the solar cell. This helps to improve the overall efficiency of the solar cell by allowing more light to be converted into electricity.
Q:Can solar cells be used in developing countries?
Yes, solar cells can be used in developing countries. They offer a sustainable and renewable source of energy that can be harnessed even in remote areas without access to electricity grids. Solar cells can provide clean and affordable electricity, helping to improve living conditions, foster economic growth, and reduce dependence on fossil fuels. Additionally, the decreasing costs and increasing efficiency of solar technology make it an increasingly viable option for developing countries.
Q:How do solar cells perform in high altitude locations?
Solar cells tend to perform better in high altitude locations due to the thinner atmosphere. With less air to scatter and absorb sunlight, solar cells can capture more solar radiation, resulting in increased energy production. Additionally, the lower temperatures at higher altitudes can also enhance the efficiency of solar cells.
Q:Can solar cells be used for off-grid power supply?
Yes, solar cells can be used for off-grid power supply. Solar cells convert sunlight into electricity, which can be stored in batteries for use when the sun is not shining. This makes solar cells an efficient and sustainable option for generating electricity in remote areas or locations without access to the power grid.
Q:Can solar cells be used on curved surfaces?
Yes, solar cells can be used on curved surfaces. Flexible solar cells have been developed that can conform to various shapes, allowing them to be installed on curved surfaces such as buildings, vehicles, or even clothing.
Q:Are bulk solar cells better than the normal solar cells?
On average, normal solar cells can not provide as much energy compared to bulk solar cells, however, if we change the material into silicon, it would.
Q:What is the lifespan of a solar cell?
The lifespan of a solar cell can vary depending on various factors, but on average, solar cells have a lifespan of around 25 to 30 years. However, with proper maintenance and care, solar cells can even last longer, sometimes up to 40 years or more.
Q:Can solar cells be used to power irrigation systems?
Yes, solar cells can be used to power irrigation systems. Solar panels can convert sunlight into electricity, which can then be used to power pumps, motors, and other components of an irrigation system. This renewable energy source can provide a sustainable and cost-effective solution for powering irrigation systems, especially in remote or off-grid locations.
Q:What are the advantages of using solar cells?
There are several advantages to using solar cells. Firstly, solar cells are a clean and renewable source of energy, which means they do not produce harmful emissions or contribute to climate change. Secondly, solar cells can be installed in remote areas without access to electricity grids, providing power to communities that would otherwise be without it. Additionally, solar cells require minimal maintenance and have a long lifespan, making them a cost-effective solution in the long run. Finally, using solar cells reduces dependence on fossil fuels, helping to conserve natural resources and promote a more sustainable future.
Q:My son is very interested in solar cells recently, and keeps asking me about the structure of a solar cell. Can anybody help me answer that question?
It's not shameful to tell your son that you have no idea, you can learn with him.
