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 PNjunction, 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:Is A grade better than the B grade when we buy the poly solar cells.
We did a test based on 10 poly solar cells we bought in the market, and it turns our 5 of the poly solar cells claimed to be A grade product is just the same as the B grade.
Q:Where can I help my company to buy the 3 Busbar Solar Cell for our project?
I would like to know the details of the solar cells project you are working on and how many 3 busbar solar cells would you like to purchase.
Q:How can the huge solar cells be applied into the market?
The huge solar cells, compared to the small one, can be more useful in some industries, such as the big factories consuming too much electricity per day.
Q:Can I buy solar cells easily online?
Not really. It's not easy to get it.
Q:Where can I find more information about the work process of solar cells
From wikipedia, where you can find almost everything you need.
Q:What is 3d solar cell? And anybody know any manufacturers?
I don’t know exactly what 3d solar cell is, but I heard that it can produce 200% of the power output of conventional solar cells.
Q:Are there any books in the market t about solar cells and their applications?
There are a lot of resources about solar cells on line, and they are cheaper.
Q:What's the relationship between solar energy materials and solar cells?
Solar cells are used for the direct conversion in changing the light energy into electrical energy. At present, a large number of terrestrial photovoltaic systems are actually made by silicon solar cells, which can be divided into silicon, polycrystalline silicon, amorphous silicon solar cells.
Q:How can I buy the solar cells wholesale ?
You can send your bidding terms to many solar cell factories by email, and let them quote the price for you. You can decide which company that gives you the best wholesale price.
Q:What is a good introduction of solar cell?
A small and simple test on the solar cell can be good to start with.
