Product Description:

 

The operation of a photovoltaic (PV) cell requires 3 basic attributes:

 

The absorption of light, generating either electron-hole pairs or excitons.

The separation of charge carriers of opposite types.

The separate extraction of those carriers to an external circuit.

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.Characteristic of Mono 156X156MM2 Solar Cells

You are gaining energy independence - add battery backup power for even greater energy security

The cost of electricity is only going to rise – insure against that rising cost

Adaptive cells change their absorption/reflection characteristics depending to respond to environmental conditions. An adaptive material responds to the intensity and angle of incident light. At the part of the cell where the light is most intense, the cell surface changes from reflective to adaptive, allowing the light to penetrate the cell. The other parts of the cell remain reflective increasing the retention of the absorbed light within the cell.[67]

 

In 2014 a system that combined an adaptive surface with a glass substrate that redirect the absorbed to a light absorber on the edges of the sheet. The system also included an array of fixed lenses/mirrors to concentrate light onto the adaptive surface. As the day continues, the concentrated light moves along the surface of the cell. That surface switches from reflective to adaptive when the light is most concentrated and back to reflective after the light moves along

Poly solar cell 156mm manufacturing process
Cell sorting - Single Welding - string jointing - splicing (the string is welded battery slice positioning, stitching together) - intermediate test (intermediate test points: Infrared testing and visual inspection) - laminated - cutting edge - layer after appearance - after layer infrared - mounted box (usually aluminum frame) - mounted terminal box - cleaning - tests (this link also points infrared testing and visual inspection of the component level determination.) - Packaging.
(1) poly solar cell 156mm test
Because of the randomness of the solar cell manufacturing conditions, produced by the battery performance is different, so in order to effectively identical or similar battery together, it should be classified according to its performance parameters; battery test through the test cell output parameters (current and voltage) of the size of its classification. In order to improve the utilization of the battery, a battery pack made of acceptable quality.
(2) poly solar cell 156mm welding positive
Main gate line, convergence with soldered to the battery positive (negative), the convergence zone for the tinned copper strip, we use a welding machine can weld with a multi-point spot welding in the form of the main gate line. Welding heat source is an infrared lamp (using infrared thermal effect). The length of the ribbon is about 2 times the battery side length. More welding belt behind the back of the welding electrode is connected to the back of the back of the battery slice.
(3) poly solar cell 156mm in series
On the back of the battery is soldered together in series to form a module string, we are currently used process is manual, locate the battery depends mainly on a membrane with plate placement battery film grooves, groove size and battery size phase corresponding to the location of tank has been designed well, different specifications of the components use a different template, the operator use a soldering iron and solder wire will "in front of the battery," the positive electrode (anode) is welded to the "behind the battery" on the back electrode (cathode) this in turn connected in series with the positive and negative components in a string of welding wire.

Q:What is the solar cell?
The structure of solar cells is diverse. Now, PN-type solar cells composed of P-type semiconductors and N-type semiconductors are used. They are mainly composed of P-type and N-type semiconductors, electrodes, and antireflection films.
Q:How is the solar cells factories working in China? Do they follow certain quality standards?
The solar cells factories in China is actually working very well. Because of the low cost and good quality, they are exporting a lot of solar cell product to overseas.
Q:How to generate solar cells, the principle of PN junction
The production of solar cells is mainly based on semiconductor materials, its working principle is the use of photoelectric materials to absorb light energy after the photoelectricity in the conversion reaction, according to the different materials used, solar cells can be divided into: 1, silicon solar cells;
Q:What is the solar cells market in China?
Solar cells, is the "ideal" energy of human being's life, solar energy has changed the traditional way of obtaining energy by battery technology. But this technology is limited due to what solar cells needs to work- the weather factors, the solar energy battery can not work properly under rainy or cloudy weather. Therefore, solar cells market is not very well developed in some part of China where there are not much sun.
Q:What are the advantages of monocrystalline silicon and polycrystalline silicon in solar power?
polysilicon, ribbon silicon, thin film materials (including microcrystalline silicon-based film, compound-based film and dye film). From the industrial development point of view, the focus from the single crystal to the direction of the development of polysilicon and film, the main reason: [1] solar head can supply more and less head and tail; [2] for solar cells, (3 hours) The production process of polysilicon is progressing continuously. The automatic casting furnace can produce more than 200 kilograms of ingot per production cycle (50 hours),
Q:How's the feedback of using 260 watt photovoltaic solar panel? Anybody ever used that?
The one I am using is up to 19% efficiency. It can be used for 24V home power generation system or grid connected.
Q:Can I buy solar cells easily online?
Yes, you can.
Q:Where can I find more information about the work process of solar cells
From wikipedia, where you can find almost everything you need.
Q:Is the Photovoltaic Cells cheap to buy?
It used to be very expensive around 35 years ago because of all the labor cost and R&D expense, but now it is not as expensive as before.
Q:Is the solar cells factory in China good and trustworthy?
We are a foreign company selling the solar cells all over the world, we actually set up our solar cell factory in China 5 years ago, and it turns out to be very good.
