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.

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:How to explain to students how the solar cells are made?
You'd better explain it step by step, following the lab experiments.
Q:How can I explain to my 10 year old daughter what solar cells are?
You should expain it to your daughter in a simpler way instead of the complicated scientic way.
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:What is the working principle of a solar cell?
The simplest way to explain this is : A solar cell converts the sun's energy into electricity.
Q:We are currently promoting our one of our solar cells seriers, which is the 156mmx156mm 6inch,2BB/3BB polycrystalline/multi solar cells,mono solar cell,made in Taiwan/Germany, please feel free to contact me if any interest.
Sounds interesting, how about the price and order requirements for this kind of solar cell?
Q:Is a solar cell expensive to make?
Not all all.
Q:Where and how can we find the best solar cells suppliers?
The good solar cell supplier won't just show up at your door, you need to dive into the solar cell market and get to know them by visiting the factories.
Q:What kind of products can be considered as the solar cell products?
Here are some of the solar cell products I can recall for now:Solar notebook, Solar-powered calculator, Solar-powered desalination unit, Solar-powered radio, Solar-powered refrigerator.
Q:What's the relationship between solar energy materials and solar cells?
Solar cells are made by the solar energy materials, which are actually basically silicon, a very developed and commonly used materials in the solar energy industry.
Q:I have a turnkey solar power project starting in 6 months, now we are searching the market in south China to find the best solar cells manufacturers. Any professional suggestion or recommendation?
As one of the manfacturers based in China who can provide most varieties of batteries, majored in rechargeable batteries: Cylindrical lithium-ion battery, lithium polymer, lithium iron phosphate, NI-MH, nickel cadmium, nickel zinc batteries; Disposable lithium batteries: Lithium manganese (3.0V).
