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

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.
