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. Proven long term mechanical stability of silicon

3. Make of highly purified poly silicon

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

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

6. Acid texturization offers a uniform appearance and virtually invisible crystal structure

7. Excellent low light behavior for improved energy yield


 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: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).
Q:What is the difference between polysilicon and monocrystalline silicon photovoltaic cells?
Monocrystalline silicon is made of polycrystalline silicon by a single crystal furnace, but also useful for the preparation of monocrystalline silicon melting. Polysilicon is the direct raw material for the production of monocrystalline silicon, which is the basic material of electronic information for semiconductor devices such as contemporary artificial intelligence, automatic control, information processing, photoelectric conversion and so on. Known as the "cornerstone of the microelectronics building."
Q:Can solar panels be charged with light?
Since the output power of solar modules depends on factors such as solar irradiance and solar cell temperature, it is not recommended to use light charging, efficiency is not only very low, and also meaningless.
Q:Can I trust the suppliers for film solar that I found on alibaba.com?
The film solar product is a mature product in the market, so most of the information of the film solar suppliers are quite transparant, which means easy to track.
Q:What are the short-circuit currents of solar cells affected by the factors?
Amorphous silicon cells: film thickness, membrane material conductivity, leakage, TCO conductivity, battery width, etc. are the factors
Q:What information can I get from the Internet about the solar cell modules? Such as what it is? How it is made?
Here is what I can found online about the solar cell module for your information: A bulk silicon PV module consists of multiple individual solar cells connected, nearly always in series, to increase the power and voltage above that from a single solar cell. The voltage of a PV module is usually chosen to be compatible with a 12V battery. An individual silicon solar cell has a voltage of just under 0.6V under 25 °C and AM1.5 illumination.
Q:What is the solar cell production process
Scientists in order to reduce the cost of solar cell manufacturing, along the two paths: one is the development of new solar cell materials, the other path is to improve the efficiency of solar cell conversion.
Q:Solar panel resistance is changed with what
To be sure that this question is very professional. Secondly, I have to answer this question: the internal resistance of solar energy, mainly reflected in the power generation, the inhibition of current. In the time of power generation,
Q:Where can I find more information about the work process of solar cells
Though the scientific website by searching solar cell work process.
Q:Many people said the usage of solar cell can reduce the cost overall, but does anyone agree with me that it actually cost a lot to operate a solar cell system?
The reason why people said that is because the solar cell is using the sunlight, which is a free resources.
