Product Description:

 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 PN 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.

Features:

1. High conversion efficiencies resulting in superior power output performance.

2. Proven long term mechanical stability of silicon

3. Make of highly purified poly silicon

4. Three bus bars for reduced series resistance and improved module and cell efficiency

5. Blue anti-reflecting coating ensures improved light absorption and increased efficiency

6. Acid texturization offers a uniform appearance and virtually invisible crystal structure

7. Excellent low light behavior for improved energy yield


 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 clients,may help you sincerely:

①What price for each watt?

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

②How 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.

③Can 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.

④What 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

• ⑤How 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.

Q:What is sun cells technology?
Sun cell technology is a advanced high power generation technology based on how the sun works on our daily life. It utilizses sun power to generate different powers in the technical way (mostly by using silicon as a transimmiter) to generate energy, and use it in our daily work and life.
Q:What are the 3 things you need to know before you start to make solar cells?
I remembered I made solar cells with my dad when I was 10 years old, and all I can remember now are the difficulties in getting the silicon working properly.
Q:Where can I buy solar cells on sale but still good quality ?
Sometimes you can find a good deal with the local manufacturers, where they sell some good quality solar cells at a pretty good price.
Q:What is a monocrystalline Silicon Solar Cells?
Monocrystalline Silicon Solar Cells consist of silicon in which the crystal lattice of the entire solid is continuous, unbroken to its edges, and free of any grain boundaries. Mono-Si can be prepared intrinsic, consisting only of exceedingly pure silicon, or doped, containing very small quantities of other elements added to change its semiconducting properties.
Q:Where can I find more information about the work process of solar cells
The working process of solar cell is a bit complicated to describle.
Q:Is the Photovoltaic Cells cheap to buy?
Photovoltaic Cells is cheaper than some kinds of solar cells because of the material that made of the Photovoltaic Cells is low cost one.
Q:I bought a new poly solar cells, and the test result of the conversion efficiency is 16.8%, is it lower than usual?
It depends on what kind os poly solar cell you are using, if it is 260 watt photovoltaic solar panel, 16.8% is a bit lower.
Q:Are bulk solar cells better than the normal solar cells?
Bulk solar cells are considered to be more powerful and functional based on the large amount usage of the solar cells.
Q:How do solar cells work to become the solar energy?
Solar energy is a term used to describe all the power and energy which is generated by the solar cells.
Q:Is the solar cells factory in China good and trustworthy?
Most of the solar cells factories are good and trustworthy because the high requirements of the Chinese government and quality standard.
