Product description

Poly Solar Cells 156*156mm B Grade Low Price

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.

What is the solar cell

A photoelectric cell designed to convert sunlight into electrical energy,typically consisting of layers or sheets of specially prepared silicon.Electrons, displaced through the photoelectric by the Sun's radiantenergy in one layer, flow across a junction to the other layer, creating avoltage across the layers that can provide power to an external circuit.Solar cells are used as power supplies in calculators, satellites, and otherdevices, and as a primary source of electricity in remote locations. 

What is a Solar Cell

A solar cell or photovoltaic cell is a device which generates electricity directly from visible light by means of the photovoltaic effect. In order to generate useful power, it is necessary to connect a number of cells together to form a solar panel, also known as a photovoltaic module. There is more about the the different types of solar cell . The nominal output voltage of a solar panel is usually 12 Volts, and they may be used singly or wired together into an array. The number and size required is determined by the available light and the amount of energy required.

73. What is the tiny little but the most efficient solar cell

While solar power promises a lot and always free compared to other energy, it's only ever going to help satisfy our energy needs if it becomes efficient enough. Fortunately, some solar cell companies has just made the world's most efficient solar cell, which converts a staggering 44.4 percent of incident light into electricity. Fossil fuels may spend less space of our energy.

The cell uses a special lens-based concentrator system, which focuses sunlight onto the cell to help improve the efficiency. Once, the light's focussed, a stack of three photo-absorption layers convert it into electricity. Even then it's no mean feat to squeeze out an efficiency of 44.4 percent, and the process saw Sharp invest a huge amount of time in tuning the device's dimensions to focus the light properly and reduce losses between layers.

While it's impressive, you probably won't see one strapped to the roof of a house any time soon. Devices this exotic are more likely to end up on a spacecraft in the first instance, where efficiency trumps cost every time. That's not to say it won't ever make it to the domestic market—it might just take a little time.

The system of solar cell

The amount of power generated by solar cells is determined by the amount of light falling on them, which is in turn determined by the weather and time of day. In the majority of cases some form of energy storage will be necessary.

In a Grid-connected system, the solar array is connected to the mains. Any surplus power is sold to the electricity company, and power is bought back from them when it is needed.

In a Stand-alone system, however, this is not possible. In this type of system the usual choice for energy storage is the lead-acid battery. The number and type of batteries is dependent on the amount of energy storage needed. Find out more about batteries

Q:What are the short-circuit currents of solar cells affected by the factors?
Silicon cell: the life of the minority after the diffusion, silicon impurity content, silicon chip resistivity, cashmere suede, PE anti-reflective film anti-reflective effect, the front gate line printing and so on affect the short-circuit current.
Q:I would like to use a ppt to show how solar cells can work in a power generation factory, can anybody share some useful information with me?
For a ppt, I think you should start with the definition of solar cells to give a basic introduction of solar cells.
Q:The history of solar cells
With the development of microelectronics technology in the twentieth century, the increasing number of miniaturized devices has made a high demand for power supply. Lithium batteries followed by a large-scale practical stage.
Q:Can the 156x156mm high efficiency single crystal cells assembly function better compared to the traditional one?
I think so, because all the research and experiments already proved that.
Q:Where can I buy solar cells?
Why do you want to buy solar cells?
Q:How to get high voltage and high current output of solar cells?
The high current solar cells means the high voltage, if you want to achieve that goal, you need to put the circuits inside the solar cells in serial-parallel.
Q:How to get high voltage, high current output of solar cells
A reasonable series of parallel can be, and increase the number of sub-batteries
Q:Can I trust the suppliers for film solar that I found on alibaba.com?
From my own experience, I think they are pretty reliable because you can search all the information including the factory's address, product details, etc. all on the website.
Q:Where can I get the most accurate information about solar cells?
The library is always the best place to go.
Q:How many years should I spend in the solar cell industry to be a good solar cells sales person?
Since the solar cell industry and market is only developed in the last 20 years, 10 years in China probably. I have to say there might not be any solar cell sales in this industry has over 10 years sales experience.
