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 working principle of a solar cell?
A solar cell is a solid-state electrical device (p-n junction) that converts the energy of light directly into electricity (DC) using the photovoltaic effect.
Q:Solar water heater plate can be directly converted into electrical energy?
Inverter: In many cases, need to provide 220VAC, 110VAC AC power supply. As the direct output of solar energy are generally 12VDC, 24VDC, 48VDC. To 220VAC electrical appliances to provide electricity, the need for solar power systems DC-AC inverters are used, and DC-AC inverters are used in some applications where DC-DC inverters are used, such as 24VDC Into 5VDC of electricity (note that not a simple buck)
Q:Why and what is the low efficiency solar cell?
The first thing we need to think about when the solar cells is becoming low efficient is to measured the reflectivity of the solar cells.
Q:The working principle of solar cells includes the three processes
In the solar cell pn junction on both sides of the lead-out electrode, and connected to the load, then in the external circuit that is generated by the photogenerated current to obtain power output, so that solar cells put solar (or other light) directly into electrical energy
Q:Is that true that the price of solar cells will be reduced in the coming year?
It is very possibile that that solar cells' price will go down this year because there were many orders last year, either from European or China market. The solar cells are actually very sustainable. Once you buy it, you can use it for years. With the falling demand the price of course will go down.
Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
The process of solar cells' conversion first requires a material which absorbs the solar energy (photon), and then raises an electron to a higher energy state, and then the flow of this high-energy electron to an external circuit. Silicon is one such material that uses such process.
Q:How to get high voltage, high current output of solar cells
Series can increase the output voltage, parallel can provide output current. Using a series parallel method to achieve, for example: need 220 volts 10 amps.
Q:How long does it take to make a solar cell?
1-2 days.
Q:What is the current situation and the recent progress space solar cells in China?
In China, the space solar cells technology is considered to be very important at the current situation, and it has already developed very dramatically after China gave financial support to the space solar cells projects.
Q:How to get high voltage and high current output of solar cells?
If you want to get the high voltage and high current output of the solar cells, you can put them in serial and serial-parallel approaches.
