Product description

Poly Solar Cells 156*156mm B Grade Low Price 3BB 4BB

A solar cell, or photovoltaic 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.[1] 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.

Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.

In contrast, a solar thermal collector supplies heat by absorbing sunlight, for the purpose of either direct heating or indirect electrical power generation from heat. A "photoelectrolytic cell" (photoelectrochemical cell), on the other hand, refers either to a type of photovoltaic cell (like that developed by Edmond Becquerel and modern dye-sensitized solar cells), or to a device that splits water directly into hydrogen and oxygen using only solar illumination.

Brief introduction of 4bb solar cell

4bb solar cells through the photoelectric effect or photochemical effect directly convert light into electrical energy, which makes use of the photoelectric conversion principle of solar radiation through the semiconductor material electrical energy transformed into a device; the photoelectric conversion process is usually called "photovoltaic hit "affect, therefore, solar cells, also known as" photovoltaic cells.

Working principle of 4bb solar cell

Foundation of working principle of 4bb solar cell is the "photovoltaic" effect semiconductor PN junction. The so-called photovoltaic effect, simply put, is that when the object is exposed to light, its charge distribution in vivo to produce an effect of EMF and current changes. In gases, liquids and solids can produce this effect, but in solid, especially in the semiconductor, solar energy is converted to electrical energy efficiency is particularly high, so the semiconductor photoelectric effect aroused special attention, the most studied, and invention of manufacturing a semiconductor solar cells.
When sun lights PN junction, the electrons in the semiconductor due to the availability of light energy and release electrons, and accordingly will produce electron - hole pairs, and the role of the barrier electric field, electrons are driven to the N-type region, holes are driven to the P-type region so that the region has a surplus of electrons N, P region has excess holes; so in the vicinity of the PN junction formed with the barrier electric field in the opposite direction of photo-generated electric field. Light green part of the field of offset barrier electric field, the rest of the P-type region is positively charged, N-type region is negatively charged; so he makes the force N region and a thin layer of P zone between the generation, namely "photovoltaic" electromotive force. When the external circuit is turned on, there will be power output.

This is the basic principle of the PN junction contact silicon 4bb solar cell power generation. If the dozens, hundreds of solar cells in series, in parallel become encapsulated solar cell module in the sunlight irradiation, the power can be obtained with a certain power output

Q:What are the advantages of monocrystalline silicon and polycrystalline silicon in solar power?
and the production process of polysilicon can be achieved by casting method and direct solidification method. Grain size of the grain size of centimeters; [4] due to nearly a decade of monocrystalline silicon technology research and development soon, in which the process is also used in the production of polycrystalline silicon cells, such as the choice of corrosion emission junction, back surface field, , Surface and body passivation, fine metal gate electrode, the use of screen printing technology can reduce the width of the gate electrode to 50 microns, the height of 15 microns or more, rapid thermal annealing technology for polysilicon production can greatly shorten the process time,
Q:The working principle of solar cells includes the three processes
The opposite of the electrical symbol of the photogenerated carriers in the solar cell pn junction built under the action of the electric field, the electron-hole pairs are separated, the electrons are concentrated on one side, the holes are concentrated on the other side, and the opposite sex charges are generated on both sides of the pn junction Of the accumulation, resulting in photogenerated electromotive force, that is, photovoltaic voltage.
Q:Is the Photovoltaic Cells cheap to buy?
Cost Of Photovoltaic Cell has dropped an amazing 99% since 1977, which is a historical statistic we can tell from the past 30 years. So I think the answer should be yes.
Q:How can I explain to my 10 year old daughter what solar cells are?
Solar cells are the cell that can collect the solar energy from nature.
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.
I am now in the process of purchasing some mono solar cells, can you send me more details of the product?
Q:How long does it take to make a solar cell?
1-2 days.
Q:The history of solar cells
Was first applied to cardiac pacemakers. As the lithium battery self-discharge rate is very low, the discharge voltage is gentle. Making the pacemaker implanted in the human body as long as possible. Lithium batteries are generally higher than the nominal voltage of 3.0 volts, more suitable for integrated circuit power. Manganese dioxide batteries, widely used in computers, calculators
Q:How about the solar cell 156mm Mono-Crystalline?
If you are getting this kind of solar cells-Mono Solar Cell measure by 156mm, the light intensity is 1000W/㎡, 25 ℃, AM1.5
Q:Is the Photovoltaic cell panel good to save the energy?
There is no doubt that the photovoltaic cell panel is very useful and efficient in saving the power in human's life, not only daily life but in other industries.
Q:Is the solar cells factory in China good and trustworthy?
5 years ago, I vistied a solar cell factory based in Inner Mongolia, and I was quite impressed by their professionalism, which gave me more confidence that they are better than we thought.
