Basic theory of Photovoltaic cells

Photovoltaics is the direct conversion of light into electricity at the atomic level. Some materials exhibit a property known as the photoelectric effect that causes them to absorb photons of light and release electrons. When these free electrons are captured, an electric current results that can be used as electricity.

The diagram above illustrates the operation of a basic photovoltaic cell, also called a solar cell. Solar cells are made of the same kinds of semiconductor materials, such as silicon, used in the microelectronics industry. For solar cells, a thin semiconductor wafer is specially treated to form an electric field, positive on one side and negative on the other. When light energy strikes the solar cell, electrons are knocked loose from the atoms in the semiconductor material. If electrical conductors are attached to the positive and negative sides, forming an electrical circuit, the electrons can be captured in the form of an electric current -- that is, electricity. This electricity can then be used to power a load, such as a light or a tool.

A number of solar cells electrically connected to each other and mounted in a support structure or frame is called a photovoltaic module. Modules are designed to supply electricity at a certain voltage, such as a common 12 volts system. The current produced is directly dependent on how much light strikes the module.

Multiple modules can be wired together to form an array. In general, the larger the area of a module or array, the more electricity that will be produced. Photovoltaic modules and arrays produce direct-current (dc) electricity. They can be connected in both series and parallel electrical arrangements to produce any required voltage and current combination.

Photovoltaic cells how they work

 

Today's most common PV devices use a single junction, or interface, to create an electric field within a semiconductor such as a PV cell. In a single-junction PV cell, only photons whose energy is equal to or greater than the band gap of the cell material can free an electron for an electric circuit. In other words, the photovoltaic response of single-junction cells is limited to the portion of the sun's spectrum whose energy is above the band gap of the absorbing material, and lower-energy photons are not used.

One way to get around this limitation is to use two (or more) different cells, with more than one band gap and more than one junction, to generate a voltage. These are referred to as "multijunction" cells. Multijunction devices can achieve a higher total conversion efficiency because they can convert more of the energy spectrum of light to electricity.

As shown below, a multijunction device is a stack of individual single-junction cells in descending order of band gap (Eg). The top cell captures the high-energy photons and passes the rest of the photons on to be absorbed by lower-band-gap cells.

Much of today's research in multijunction cells focuses on gallium arsenide as one (or all) of the component cells. Such cells have reached efficiencies of around 35% under concentrated sunlight. Other materials studied for multijunction devices have been amorphous silicon and copper indium diselenide.

As an example, the multijunction device below uses a top cell of gallium indium phosphide, "a tunnel junction," to aid the flow of electrons between the cells, and a bottom cell of gallium arsenide.

Q:How does the solar panel produce it yourself?
 Step 5: Assemble the battery Place the titled titanium dioxide film face up on the table, drop one or two drops of electrolyte containing iodine and iodide ions on the membrane, and then press the conductive surface of the counter electrode down on the titanium dioxide film The The two pieces of glass were slightly staggered so as to use the exposed portions as the electrodes for testing. Use two clips to hold the battery, so that your solar cell is made
Q:What is the internal structure of solar panels
EVA used to bond fixed glass and power generation body (such as battery), transparent EVA material directly affect the quality of the component life, exposure to air in the EVA easy to aging yellow, thus affecting the component's light transmittance, thus
Q:What is Solar Cell Technology?
A technology which converts the sun power into the electricity.
Q:Which Solar Panel Type is best? Polycrystalline panel or PV Module Monocrystalline Solar cell panel, or thin film?
PV Module Monocrystalline Solar cell panels is most efficient since they are made from the highest-grade silicon.
Q:Can anybody tell me the power supply of the home solar cell?
l can give you an example as following: 40W * 4H=160Wh=0.16 degree power In accordance with the summer sunny weather one day 5 standard sun, consider 70% system efficiency 160 / 5 / 70%=45.7W, so 50 Watt Solar cell is enough.
Q:What information can I get from the Internet about the solar cell modules? Such as what it is? How it is made?
Solar cell module is an assembly of photovoltaic cells. It can be used as a component of a larger photovoltaic system in order to generate electricity. A photovoltaic system usually includes an array of solar panels and an inverter. It may also sometimes contain a battery or solar tracker as well as interconnection wiring.
Q:Is solar cell technology very developed and v applied to life a lot?
Ever since scientists discovered the solar cell, it has been very much a part of our life.
Q:Do you believe you can make a solar cell by using kitchenware?
You must be joking.
Q:How is the solar panel and the battery connected?
In the case of solar power to charge the battery at the same time, the battery power supply is completely feasible, in this case, the load will use the power of electricity directly to the use of solar cells, the remaining charge to the battery; the contrary, if the solar battery power is not enough , Will also take electricity from the battery at the same time.
Q:Is silicon-based solar cells and silicon-based thin-film solar cells the same?
Silicon-based solar cells include silicon-based thin-film solar cells, including monocrystalline silicon solar cells and polycrystalline silicon solar cells. Silicon-based thin-film solar cells can only be in the form of thin-film silicon-based solar cells.
