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.


How to Make Solar Cell in Home

Solar cells have a huge usage in home. If you want to get a solar cell at home, you can light up your little things like a clock, radio, etc. And here some steps to make solar cells . First, take a copper sheet and cut it into equal parts. After cutting, you have 2 pieces of the same size. Step2: Heat up one piece of copper sheet completely using a burner or gas stove. Heat up 20 to 30 minutes. Then place it undisturbed to cool down. Step3: Attach a piece of copper wire to it. Clear that place where you will attach copper wire to it. Step 4: Take another piece of copper sheet and attach it to another piece of copper wire. Step5: Take a plastic bottle and cut it half. In the bottom part of bottle make a solution of hot water and salt. Step6: Paste burned copper sheet in the bottle. Only copper sheet touched with water not copper wire. Step7: In opposite direction paste another piece of copper sheet. Step8: Now your solar cell is ready to be attached to anything to the wire which is attached to copper sheets.

How to Build your own Solar Cell

Step 1: Stain the Titanium Dioxide with the Natural Dye: Stain the white side of a glass plate which has been coated with titanium dioxide (TiO2). This glass has been previously coated with a transparent conductive layer (SnO2), as well as a porous TiO2 film. Crush fresh blackberries, raspberries, pomegranate seeds, or red Hibiscus tea in a tablespoon of water. Soak the film for 5 minutes in this liquid to stain the film to a deep red-purple color. If both sides of the film are not uniformly stained, then put it back in the juice for 5 more minutes. Wash the film in ethanol and gently blot it dry with a tissue.
Step 2: Coat the Counter Electrode: The solar cell needs both a positive and a negative plate to function. The positive electrode is called the counter electrode and is created from a "conductive" SnO2 coated glass plate. A Volt - Ohm meter can be used to check which side of the glass is conductive. When scratched with a finger nail, it is the rough side. The "non-conductive" side is marked with a "+." Use a pencil lead to apply a thin graphite (catalytic carbon) layer to the conductive side of plate's surface.
Steps 3: Add the Electrolyte and Assemble the Finished Solar Cell: The Iodide solution serves as the electrolyte in the solar cell to complete the circuit and regenerate the dye. Place the stained plate on the table so that the film side is up and place one or two drops of the iodide/iodine electrolyte solution on the stained portion of the film. Then place the counter electrode on top of the stained film so that the conductive side of the counter electrode is on top of the film. Offset the glass plates so that the edges of each plate are exposed. These will serve as the contact points for the negative and positive electrodes so that you can extract electricity and test your cell. Use the two clips to hold the two electrodes together at the corner of the plates. The output is approximately 0.43 V and 1 MA /cm2 when the cell is illuminated in full sun through the TiO2 side.

Q:What is the working principle of a solar cell?
It's not easy to explain in a simple way.
Q:I am working on research for the usage of solar cells, where can I find more news of solar cells?
www.solardaily.com could be the website that you are looking for.
Q:Solar cell life for several years
In physics called solar photovoltaic (Photovoltaic, photo light, voltaics volts, abbreviated as PV), referred to as photovoltaic.
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 is a polymer solar cell and how does it work?
It's one kind of solar cell that works in the same way as other solar cells do.
Q:Do you believe you can make a solar cell by using kitchenware?
You must be joking.
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:How long does it take to make a solar cell?
It only took me 1 day because I had all the required materials ready before I start to make it.
Q:How can the solar power change our life by using solar cells material?
100 years ago, no human being could ever dare to imagine that we can use solar cells to generate solar power to better change our life. Today it is happening everyday!
Q:Is the solar cells factory in China good and trustworthy?
I can only say 50% of the solar cell factories in China are good, and they can meet your quality standard, while the other 50% of the solar cell factories are not very reliable.
