Product Description:

Solar Cells:

solar cells, when struck by photons of light from the sun, generates an electrical current which can then be used to power DC or AC electrical loads.
A solar cell is made of silicon. Computer chips are made of this same material. Basically, when light strikes the surface of a solar cell some of it is absorbed into the silicon. This light energy bumps the electrons loose and causes energy to flow

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 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.

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?
Thin film solar cell is a kind of solar cell which is cheaper than the others.
Q:Can the solar powered cells really work better than the normal cells?
Because of the different ways of generating the power, the solar powered cells definitely better than the normal cells in the modern world.
Q:Can somebody list some of the materials used for making solar cells?
There are quite many materials to make a solar cell, but silicon is something you need to have.
Q:How does the solar cell work properly?
The material which is used to absorb the energy from sunshine should be silicon.
Q:Is solar cell technology very developed and v applied to life a lot?
Yes, solar cells are very commonly used in the commercial military, industrial, areas.
Q:Is silicon-based solar cells and silicon-based thin-film solar cells the same?
Silicon-based solar cells include silicon-based thin-film solar cells, including monocrystalline silicon solar cells and polycrystalline silicon solar cells. Silicon-based thin-film solar cells can only be in the form of thin-film silicon-based solar cells.
Q:What is the window material in the solar cell? what's the effect?
However, since the window layer is a surface layer, the surface composite is serious, so the window layer to avoid absorbing light to produce carriers, so the window layer is generally made of large band gap material, try not to absorb light.
Q:On the parallel connection of solar cells
Whether you say more than one solar cell is in series or parallel, it depends on your use requirements to decide if the parameters of solar cells are basically the same, and you need a relatively high "use" voltage, that can The battery in series, if you need a larger operating current and the voltage does not need high, you can connect multiple solar cells in parallel to get a higher output current;
Q:Why and what is the low efficiency solar cell?
Sometimes the solar cells made of bad quality silicon can cause the result that the solar cells you are using is lower efficient than when you started to use it. You might need to change some materials.
Q:What is the usage of solar cells?
Solar cells can be used in many different places, such as the power supply factories.
