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.

Q:Why are the poly Solar cell specifications is different from each other, they seem to have the different size of 125mm, 156mm, 152mm, is the 152mm's battery technology is higher than the other?
To make is simple first, the numbers you saw such as 125mm, 156mm, 152mm, refers to the diameter of the silicon wafer.
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:I bought a new poly solar cells, and the test result of the conversion efficiency is 16.8%, is it lower than usual?
The PV solar cells should be around 18%, any solar cells under that rate is not very efficient.
Q:Are bulk solar cells better than the normal solar cells?
Yes, the bulk solar cells are better than normal solar cells because its power supply is bigger than the normal solar cells.
Q:Monocrystalline silicon and polycrystalline silicon cell in the appearance of what is the difference?
For the user, monocrystalline silicon cells and polysilicon batteries are not much different. Monocrystalline silicon and polycrystalline silicon cell life and stability are very good.
Q:Is the Solar Power Photovoltaic Cells the same as PV cells modules?
According to the application needs, solar cells after a certain combination, to achieve a certain rated output power and output voltage of a group of photovoltaic cells, called PV modules
Q:Why and what is the low efficiency solar cell?
The technical problems will cause the low efficienct of the solar cells, including solar and thermal energy, solar cells are now either absorb light energy, or absorb heat, there is little light and heat absorbed together.
Q:How many types of solar cells are now being used in real life?
3 kinds of solar cells, Silicon-based, organic, chemical.
Q:How many years should I spend in the solar cell industry to be a good solar cells sales person?
Personally, I think 4 years will be good enough to be a really good solar cells sales, and you can accumulate a lot of client based and resources.
Q:What is the most commonly used material for solar cells?
It is mainly the crystalline silicon materials (including polysilicon and monocrystalline silicon), its market share in more than 90% and in the future for a long period of time will still be the main material of solar cells.
