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:Anybody ever heard of thin film solar cell? What it that?
From the information I got from wikipedia, A thin-film solar cell is a second generation solar cell that is made by depositing one or more thin layers, or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic or metal.
Q:How is the solar cells factories working in China? Do they follow certain quality standards?
Of course, the follow the quality assurance standard, and in fact, they are as good as the solar cell factories in US.
Q:How does the photovoltaic cells work?
Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity.
Q:Can I buy solar cells easily online?
Maybe, but it takes time to deliver it to you.
Q:Do you believe you can make a solar cell by using kitchenware?
As a scientist, I think it's possible.
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:Are bulk solar cells better than the normal solar cells?
It's hard to just simply say the bulk solar cells are better than normal solar cells. If the normal solar cells are better designed, it might be better than bulk solar cells.
Q:How many types of solar cells are now being used in real life?
Many many types.
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: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.
