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:Briefly explain why solar cells are made into components
The electrical performance parameters of solar cells are: voltage, current, capacity, type, charging rate and so on. The voltage parameter of the battery refers to the operating voltage of the battery, that is, the voltage that can be supplied to the device. Current, refers to the maximum discharge current of the battery. Capacity, refers to the total discharge power of the battery, with An / hour (A / H) said.
Q:Solar panel resistance is changed with what
To be sure that this question is very professional. Secondly, I have to answer this question: the internal resistance of solar energy, mainly reflected in the power generation, the inhibition of current. In the time of power generation,
Q:The difference between a fuel cell and a solar cell
At present fuel cell system fuel - power conversion efficiency of 45% to 60%, while the thermal power and nuclear power efficiency of about 30% to 40%. (2) Hazardous gases SOx, NOx and noise emissions are low CO2 emissions are greatly reduced due to high energy conversion efficiency, no mechanical vibration.
Q:Is the polymer solar cell the cheapest type among all the different kinds of solar cells?
Yes, the polymer solar cells are the cheaper type.
Q:How does the solar cell work properly?
Silicon, as one of the most important semi-conductor material, plays a vital part in how to make the solar cells work.
Q:Is solar cell technology very developed and v applied to life a lot?
Yes, solar cells are very commonly used in the commercial military, industrial, areas.
Q:What is the current situation and the recent progress space solar cells in China?
The space solar cells is uniquely designed for the power supply for the space, which is very expensive to build and maintain.
Q:Can a solar cell be used in commercial buildings?
Yes, of course, it can .
Q:How much does a solar cell cost?
If you are using a solar system at home, you may find it from your electricty bill.
