Product Description:


 

Polycrystalline Silicon Solar Cells:

Solar cells is made by solar wafer, it has three categories of solar cell right now, monocrystalline polycrystalline and thin film,These cells are entirely based around the concept of ap-n junction, which is the critical part of solar module, it is the part that can convert the light energy into electricity, the thickness is from 180um to 200um, with even busbars to conduct electricity, textured cell can decrease diffuse reflection; they are often electrically connected and encapsulated as a module. Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting  semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage. Connecting cells in parallel will yield a higher current;With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.

Polycrystalline Silicon Solar Cells Advantage:

•  High efficiency and stable performance in photovoltaic conversion.
•  Advanced diffusion technique ensuring the homogeneity of energy conversion efficiency of the cell.
•  Advanced PECVD film forming, providing a dark blue silicon nitride anti-reflection film of homogenous color and  attractive appearance.
•  High quality metal paste for back surface and electrode, ensuring good conductivity, high pulling strength and ease of soldering.
•  High precision patterning using screen printing, ensuring accurate busbar location for ease with automatic soldering a laser cutting.

FAQ

We have organized several common questions for our clientsmay help you sincerely

What price for each watt?

It depends on the efficiency of the solar cell, quantity, delivery date and payment terms.

How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served.

Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Yes, we can, we have two companies for solar region, one is CNBM International, the other is CNBM engineering Co.

We can provide you not only the solar module but also the off grid solar system, we can also provide you service with on grid plant.

What is your warranty of solar cell?

 Our product can promise lower than 0.3% open box crack, we support claim after opening the box if it has crackm color difference or sth, the buyer should give pictures immediately, we can not accept the claim after the solar cell has assembled to solar panel.

• Timeliness of delivery

• How do you pack your products?

We have rich experience on how to pack the solar cell to make sure the safety on shipment, we could use wooden box or pallet as buyer's preference.

 Can you do OEM for us?

Yes, we can.

 

  

 

Solar power has been able respected, more and more widely used, in large part because it is environmentally friendly way of generating renewable power generation process does not produce carbon dioxide and other greenhouse gases, will not pollute the environment, and therefore widely. From the current terms of the types of solar cells, including crystalline silicon cells, thin film batteries and other battery materials. Monocrystalline silicon cells are divided into cells, polycrystalline cells and amorphous silicon thin-film batteries.

For solar cells, the most important parameter is the photoelectric conversion efficiency, developed in the laboratory of silicon-based solar cells, Monocrystalline silicon cell efficiency of 25.0%, polycrystalline silicon cell efficiency of 20.4%, CIGS thin-film cell efficiency of 19.6%, CdTe thin film cell efficiency of 16.7%, an amorphous silicon (amorphous silicon) thin film battery efficiency of 10.1%, while in practical application efficiency is slightly lower this level.

We are familiar with crystalline silicon cells into single crystal and polycrystalline, except that the silicon wafers. Monocrystalline wafers made of polysilicon raw material crystal pullers pull into a bar and then sliced into monocrystalline, polycrystalline silicon film is made of polysilicon through ingot casting furnaces made of polysilicon ingots and then sliced. Since the difference between the fabrications of polycrystalline silicon solar cell battery much. But the conversion rate, the current conversion rate of monocrystalline silicon cells generally 16% to 18% conversion rate of polycrystalline silicon cells generally 15% to 16%. From the comparison of production costs, polycrystalline silicon cells cheaper materials manufacturing simple, to save power consumption, lower overall production costs, get a lot of development. Therefore, polycrystalline silicon cells accounted for two-thirds of the amount of crystalline silicon cells, accounting for over 55% of the solar cell market share. However, although the cost of polysilicon occupies advantage, in addition to the conversion rate lower than the silicon, its service life is shorter than the Monocrystalline silicon solar cells.

Q:What is 3d solar cell? And anybody know any manufacturers?
There are several hot spots in the research of solar power generation, one of which is the use of three-dimensional solar energy technology to replace the current popular flat solar cell.
Q:What is the best way to deal with surplus solar cells abandoned after burning?
Unfortunately abandoned solar cells are not easy to recycle. Only the aluminium frame can be reused, and the surplus is sometimes inseparable; because the solar cell contains silicon, tin, nickel, silver metal.
Q:Can the 156x156mm high efficiency single crystal cells assembly function better compared to the traditional one?
Our company is planning to upgrade our supply system into the 156x156mm high efficiency single crystal celsl assembly, but we are still not sure if it is really that great.
Q:What is Solar Cell Technology?
A technology which converts the sun power into the electricity.
Q:Why are the poly Solar cell specifications is different from each other, they seem to have the different size of 125mm, 156mm, 152mm, is the 152mm's battery technology is higher than the other?
Most of the popular products in the market is 125mm or 156mm, because the 152mm is not really practically useful in the market.
Q:What are the advantages of monocrystalline silicon and polycrystalline silicon in solar power?
and the production process of polysilicon can be achieved by casting method and direct solidification method. Grain size of the grain size of centimeters; [4] due to nearly a decade of monocrystalline silicon technology research and development soon, in which the process is also used in the production of polycrystalline silicon cells, such as the choice of corrosion emission junction, back surface field, , Surface and body passivation, fine metal gate electrode, the use of screen printing technology can reduce the width of the gate electrode to 50 microns, the height of 15 microns or more, rapid thermal annealing technology for polysilicon production can greatly shorten the process time,
Q:Is there any easy way to make a solar cell? I want to make a DIY solar cell with my child at home.
I sent a private message to you about my personal experience of diy solar cell.
Q:My solar cells are broken, can I just buy one and replace it?
It's a bit risky to do that by yourself.
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.
Q:24V 200W solar cells can charge 12V battery?
Please be assured that bold direct charge to ensure that nothing is ok. If the heart is not a few words to find a 0-20 amps ammeter to measure the charging current, Ye Hao master the charging time.
