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 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.

Features:

High efficiencies up to 16.4%

Proven long term mechanical stability of silicone

Make of highly purified poly silicone

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

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

Acid texturization offers a uniform appearance and virtually invisible crystal structure

Excellent low light behavior for improved energy yield

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 the difference between polysilicon and monocrystalline silicon photovoltaic cells?
Can be used for diode-level, rectifier device-level, circuit-level and solar cell-level single crystal products production and deep processing and manufacturing, and its follow-up products integrated circuits and semiconductor separation devices have been widely used in various fields, military electronic equipment also occupies an important position The
Q:How does the solar cell work in terms of photochemical conversion?
If impurities are incorporated into the true semiconductors, i.e. monocrystalline silicon, for example, incorporation of pentavalent phosphorus (P), excess electrons are called, which are called N-type semiconductors.
Q:Can solar panels be charged with light?
When the light is irradiated on the surface of the solar cell, a part of the photons are absorbed by the silicon material; the energy of the photon is transferred to the silicon atoms so that the electrons are transitioned and the free electrons are formed on both sides of the PN junction to form a potential difference.
Q:How long does it take to make a solar cell?
It is now mass produced, so it doesn't take long to make it in the factory.
Q:Solar cells and the difference between ordinary batteries. Why is the solar cell is converted into electrical energy, zinc battery is what is converted into chemical energy
Solar cells do not need to consume chemical substances, as long as there is sunshine will be electricity; ordinary battery must be a chemical reaction will be generated. Solar cells in the absence of time can not power, ordinary battery without this limit.
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:Is it possible to learn how to make solar cells by yourself?
A solar cell can be made very simply by using a sheet of copper and some other materials. So the answer is yes!
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 solar cell production process
Will be inexhaustible sunshine into the benefit of mankind for the benefit of electricity, the core technology is the solar cell photoelectric conversion rate.
Q:Is it complicated to make a solar cell work well?
For the professionals, it is not complicated at all.
