Brief Introduction of Solar Cells

A solar cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.

Advantage of  Monocrystalline Solar Cells

•  High efficiency and stable performance in photovoltaic conversion.

Usage of Monocrystalline Solar Cells

Solar cells 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 the 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; our solar cells have passed IEC Certification. With high and stable quality, our cells can greatly improve the performance of Solar Modules.

FAQ

We have organized several common questions for our clientsmay help you sincerely

What price for each watt?

It depends on the efficiency of the solar cell, quantity, delivery date and payment terms.

How 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.

Can 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.

What 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

• How 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.

 Can you do OEM for us?

Yes, we can.

 

Research direction of solar cell supplier

Now what solar cells suppliers are researching for? I think we all know the past few years, the photovoltaic industry in a slump, the reason that the industry cannot get rid of supporting policies is that the production costs are too high, so now all of them are desperately looking for a low-cost solar cell system, in the early stage of new materials or even tolerate its efficiency is very low. These low-cost battery can be attributed to the third generation of solar cells in the family, but also the story from 20 years ago talking about: the first line is the year Kodak has not closed down, a Chinese researcher found that organic dyes can also produce the photoelectric effect. Then European scholars dioxide nanoparticles staining, actually made an 8% efficiency solar cell chemistry, which is a dye-sensitized cells, 13% of the world record two years ago after the last time he climbed nature almost extinct from academia. The second line is a conductive organic Nobel Prize, we have to study photoelectric conversion, electric light switch or is organic led display, commercial very successful, who knows dynasty transfer power (that is, the solar cell) was actually a pit. But the Nobel laureate is still hopeful to open an organic photovoltaic company to give the Clinton administration's strong support; the result has been wiped out in order get the 2008 financial crisis. The battery has just broken the world record 10% of it. The third line is to make dye-sensitized cells found in the Japanese organic-inorganic hybrid material which can replace the perovskite structure of the dye, the efficiency of 3%. Europeans found that the material itself is a good photovoltaic semiconductor material, is now the world record by the Korean remained at 20%, last month issued a science. These three lines of batteries are the order of the temperature at room temperature with a chemical solution can be synthesized, lower cost than silicon cells, the question is not high enough efficiency lifetime is not long enough, but due to the relatively low barriers to entry (chemical laboratory on the line) Therefore worldwide research group particularly impact factor in the field have gone.
Now what solar cells suppliers are researching? Simply put, that is efficient and cost. Close to the production of research and development, the first is the original laboratory can efficiently process into mass production process, such as PERC, HIT, IBC, etc; more front-end development, is looking for more efficient and lower cost of battery cells materials, such as laminated battery, battery perovsk

Q:The history of solar cells
The earliest lithium battery came from the great inventor Edison. As the chemical properties of lithium metal is very lively, making lithium metal processing, preservation, use, the environment is very high. Therefore, lithium batteries have not been applied for a long time.
Q:The difference between a fuel cell and a solar cell
Fuel cell is very complex, involving chemical thermodynamics, electrochemistry, electrocatalysis, materials science, power systems and automatic control and other disciplines of the theory, with high power generation efficiency, less environmental pollution and so on.
Q:Can the 156x156mm high efficiency single crystal cells assembly function better compared to the traditional one?
Yes, according to our research and development, we have statistics to show that the 156x156mm high efficiency single crystal cells assembly does function better compared to the traditional one.
Q:Is the polymer solar cell the cheapest type among all the different kinds of solar cells?
I am not sure about that.
Q:Does the solar cell generate electricity in the absence of the sun, only in the case of strong lights or lasers? If you can achieve how much, and the same day?
Sunlight is a composite light, in which only the frequency is greater than the solar cell threshold photons can effectively stimulate the solar cell power generation.
Q:What information can I get from the Internet about the solar cell modules? Such as what it is? How it is made?
A solar cell module has a chamber and includes a solar cell device, a gel /fluid, and a light-focusing unit. The solar cell modules are basically a group of solar cells used a specific function.
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:My solar cells are broken, can I just buy one and replace it?
Of course you can.
Q:How much does a solar cell cost?
Figuring out exactly the cost of the solar system you have can take a little detective work.
Q:Silicon solar cell power generation principle
The expected efficiency of the theory is 24% .As the semiconductor PN junction device in the sun under the photoelectric conversion efficiency of the highest, so these photovoltaic devices are usually referred to as solar cells, also known as photovoltaic cells or solar cells.
