Brief introduction of Monocrystal Solar Energy Cell

Silicon rods, materials performance indicators in order to reduce production costs, and now terrestrial applications such as solar cells using solar grade somewhat relaxed. Some also use semiconductor device processing materials and discard the head and tail of silicon materials, solar cells drawn into complex dedicated silicon rods.
The silicon rods cut into pieces, usually 0.3 mm thick sheet. Processing solar cells, the first doping and diffusion in silicon, a trace amount of dopant is generally boron, phosphorus, and antimony. Diffusion is carried out in a quartz tube into a high-temperature diffusion furnace. Thus formed P> N junction on the wafer. Then using a screen printing method, fine with a good paste into a grid line printed on the wafer, after sintering, while forming the back electrode and the surface coated with antireflection gate line source to prevent a large number of photons it is reflected off the smooth surface of the wafer. Thus, the monomer Monocrystal solar energy cells are produced. After single-chip random testing can be assembled according to the required specifications into a solar cell module (solar panel) by the method of series and parallel to a certain output voltage and current.

Difference between Monocrystal Solar Energy Cell and polycrystalline silicon solar panels:

Polycrystalline silicon solar cells and Monocrystal solar energy cells is no different. Life and stability of polycrystalline silicon solar cells and Monocrystal solar energy cells are good. Although the average conversion efficiency of silicon solar cells is higher than the average conversion efficiency of polycrystalline silicon solar cells of about 1%, but because of Monocrystal solar energy cells can be made quasi-square (four to the top of the arc), when the composition of the solar cell module when there is a part of the area filled up, and polycrystalline silicon solar cells are square, there is no problem, so the efficiency of the solar cell module is the same.
In addition, because the manufacturing process two types of solar cell materials is not the same, polycrystalline silicon solar cell manufacturing process energy consumed than Monocrystal solar energy cells is about 30% less.

Q:How to get high voltage and high current output of solar cells?
Well, there is a scientific way which can help you to get the high current solar cells, but it can only be used in the experiment.
Q:Can the 156x156mm high efficiency single crystal cells assembly function better compared to the traditional one?
I think so, because all the research and experiments already proved that.
Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
The process of solar cells' conversion first requires a material which absorbs the solar energy (photon), and then raises an electron to a higher energy state, and then the flow of this high-energy electron to an external circuit. Silicon is one such material that uses such process.
Q:How to explain to students how the solar cells are made?
The best way to explain that to students is to take them to a solar cells workstation if possibile.
Q:I bought a new poly solar cells, and the test result of the conversion efficiency is 16.8%, is it lower than usual?
I don't think it's lower than normal, 16.8% is pretty common in most of the power plants in my area.
Q:Is that true that the price of solar cells will be reduced in the coming year?
It is very possibile that that solar cells' price will go down this year because there were many orders last year, either from European or China market. The solar cells are actually very sustainable. Once you buy it, you can use it for years. With the falling demand the price of course will go down.
Q:What is the accurate explanation for the sun solar cell power system? How does it work?
The sun solar cell Power supply system is composed of solar cell module, storage battery and monitoring device.
Q:How does a solar cell raise industrial efficiency?
Solar Cell Efficiency refers to the portion of energy in the form of sunlight that can be converted via photovoltaics into another more useful form, namely electricity.
Q:What is the most commonly used material for solar cells?
The most commonly used solar cells material is the solar photovoltaic (PV) cells. They are used for the direct conversion of light energy into electrical energy. At present, a large number of terrestrial photovoltaic systems are made by silicon solar cells, which can be divided into silicon, polycrystalline silicon, amorphous silicon solar cells.
Q:Can I trust the suppliers for film solar that I found on alibaba.com?
I have been doing business on alibaba.com for over 10 years, and I seldom came across the unreliable suppliers from alibaba.com. Therefore, I should say I do trust the suppliers I found.
