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. Outstanding power output even in low light or high temperature conditions

3. Optimized design for ease of soldering and lamination

4. Long-term stability, reliability and performance

5. Low breakage rate

6. Color uniformity


 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:I would like to use a ppt to show how solar cells can work in a power generation factory, can anybody share some useful information with me?
I have a ppt which was for my presentation of solar cell research I did when I was in univeristy, I can share with you if you need it.
Q:Which one is better on the solar cells panel? The Monocrystal Solar Energy Cell or photovoltaic cell?
The Monocrystal Solar Energy Cell and photovoltaic cells both has its advantage and disadvantage, so it really depends on what you use them for.
Q:How to make solar cells in a scientific way?
As far as I can remember, you do need some salt for making solar cells.
Q:Which brand of the solar cells is sold with the lower price on the market? Which brand is more practical for the countryside?
Our price of the solar cell is low and very competitive in the market, but we can still guarantee you that we provide you the best quality.
Q:What is the best way to deal with surplus solar cells abandoned after burning?
It could be a very good resource to be used, but the technology needs to be more advanced to really deal with that.
Q:I bought a new poly solar cells, and the test result of the conversion efficiency is 16.8%, is it lower than usual?
Since you mentioned that your poly solar cells is a newly bought one, I strongly recommend you to ask your supplier.
Q:What are the 3 things you need to know before you start to make solar cells?
Sorry that I can not provide any help because I know nothing about solar cells.
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: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?
The poly solar cell which is 156mm is not necessary high technology-based than the others. In fact, it's less efficient than the others.
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.
