Monocrystalline silicon solar cells

As we are familiar with some of the street lamp, basically is the solar energy and LED. That, of course, there is a big difference between the two, but they are now still was the cause of our large area is used, or because they are energy conservation and environmental protection, and

as we are familiar with some of the street lamp, basically all is solar energy and LED. That, of course, there is a big difference between the two, but they are now still was the cause of our large area is used, or because they are energy conservation and environmental protection, and more convenient. Since our progress of science and technology, we can use some more intelligent sensing system, so there is no need for manual operation we solar street lamp, can according to some fixed law of automatic switch. He can not do without the use of solar cells, then we can for him an analysis of the solar cells made of different materials and choice. Monocrystalline silicon solar battery photoelectric conversion efficiency is about 18%, the highest of 24%, this is all kinds of solar cells photoelectric conversion efficiency highest, but the production cost is very big, so it can not be used widely. Due to the commonly used single crystal silicon and waterproof resin toughened glass encapsulation, LED street light, so its durable, service life of 25 years. The making craft of polycrystalline silicon solar cell and single crystal silicon solar cell is similar, but the polycrystalline silicon solar battery photoelectric conversion efficiency is to reduce a lot, the photoelectric conversion efficiency is about 16% less.

in terms of production cost is cheaper than monocrystalline silicon solar cells, the material is simple, save power consumption, the total production cost is low, so get a lot of development. In addition, the service life of the polycrystalline silicon solar cells will also shorter than monocrystalline silicon solar cells. As for the price performance ratio, monocrystalline silicon solar battery is slightly better. So, choose solar battery material is also very important, think now a lot of solar street lights, they will be for this kind of battery development emphatically. Guangdong burns lighting co. , LTD. , specializing in the production of solar energy and green lighting products. The whole lamp warranty for two years, the problems in the process of product use guarantee response within 24 hours, solution within 7 working days ( Domestic users)
