OUR AFFILIATIONS
How does Solar Panels generate Power
The physical basis for solar cells is the photoelectric effect. Experiments had been done in which both light frequency and light intensity were varied. If the frequency was below a certain characteristic value (a different frequency for each material), nothing was observed to happen no matter how intense the light was made. For frequencies above that critical value, electrons were observed near the surface of the material. If the intensity of the light was increased, many more electrons came away from the material. If the frequency was increased, the electrons moved away from the material with greater kinetic energy.
In the solar cell, the photoelectric effect can act in a similar way to generate electrons,with the proviso that the electrons do not leave the surface of the material. Of course, in most materials, recombination of the electron with the ion is almost immediate. Only materials or devices in which it is possible to prevent recombination are candidates for solar cell building materials. Materials called semiconductors are used to make solar cells. To prevent recombination, two different types of doped semiconductor are grown together to make the solar cell. Pure silicon is grown in a furnace in the presence of silicon vapor. The silicon vapor is doped with acceptors or donors (p-type and n-type semiconductors) to deposit layers of p-type or n-type material.
Why solar cells are known as photovoltaic, or PV, cells
The word photovoltaic is made up of pieces, with photo- indicating light, and voltaic implying that a potential difference (measured in volts) is set up by the action of the light.The light directly liberates electrons, and the diode action insures that the current of electrons flows only one way.So, as long as light is incident on the solar cell, charges will be produced by the photoelectric effect and the current will flow. When there is no light, there is not a current.
Solar cells work to make light into electricity directly. When light shines, electrons are liberated in the p-type region and holes produced in the n-type region; this lowers the potential energy barrier at the junction. A current flows and establishes an external potential difference. Solar cells act in a way similar to the diode, so that current can flow in only one direction when the cell is exposed to light
The cells are single wafers of semiconductor. Each wafer can put out a small amount of power at the potential difference (voltage) determined by its band gap physics. To use the cells, they must be assembled into larger structures, and then into even larger structures.
Material used in solar cells
The most popular choice for solar cells is silicon (Si),production cell efficiencies of about 12%,(110-113) and a maximum efficiency of about 15%, and gallium arsenide and a maximum efficiency of about 22%The maximum theoretical efficiency for a single cell is 33%. For multiple cells, the theoretical maximum is 68%.(104) Both of these materials must be grown as single crystals under very precisely controlled conditions to minimize imperfections, which can cause recombination. The large crystals are then sawn to make thin slabs of solar cell and equipped with electrodes.
Types of Solar Cells
- Crystalline silicon cells
Crystalline silicon cells are manufactured very carefully. In the original setup, a starter was dipped into a vat of molten silicon (~ 1400 °C), and a single crystal slowly formed as the crystal was drawn out over a long period of time. It was essential to the process that uniformity be maintained. Nowadays, the process is more automated and requires less care. The cells need to be at least 100 mm thick because of problems with absorption; the thickness helps allow the light to be absorbed
- Polycrystalline thin films
Polycrystalline wafers are made by a casting process in which molten silicon is poured into a mold and allowed to set directly into ingots in layers (a layer at a time) rather than grown as a single crystal. it is of poorer quality but cheaper and has less environmental impact. Sheets of silicon have also been grown by two methods: the edge-defined,film fed, growth ribbon process, in which the silicon rises by capillary action between two graphite plates; and the dendritic web process, pulling a thin film of silicon between two spacers from a molten surface that grows.
One advantage of polycrystalline thin films is that there is no light-induced degradation of performance. Thin films (1 mm to 10 mm thick, absorbing 90% of light) are made of gallium arsenide (GaAs) or cadmium telluride (CdTe); these are more efficient than silicon in multi-stack orientation because of their larger band gaps.Both crystalline and polycrystalline semiconductors of silicon can be bonded to a plastic or glass material, which allows light through and provides structural integrity. It also provides protection from the elements and leads to various applications where maintenance is difficult to do, since none is needed except an occasional cleaning. Efficiencies as high as 32.6% have been demonstrated in the lab for such multijunction cells.
An additional advantage of polycrystalline silicon is the ease with which large structures can be made. Single crystal cells must be carefully interconnected electrically, whereas the polycrystalline silicon can be made essentially as large as desired
- Single and multijunction cells
Most current photovoltaic materials are made of a single layer of light absorber. However, given the differences among solar cells in terms of the energy they absorb, it can be advantageous to “stage” or layer them. Cells of different bandgaps stacked atop one another are known as multijunction cells.
- Amorphous cells
Materials that have no crystal structure are classed as amorphous, from the Greek, meaning “lack of structure.” Amorphous silicon has no crystal structure, and its atoms are ordered over only a very short distance; small pieces of silicon crystal abut one another at random orientations in such a way that no long-distance structure exists. Amorphous silicon solar cells in thin films exhibit better absorption than pure silicon (40 times as efficiently as crystalline silicon), but because of the many structural defects, they are only about 11% efficient at maximum, and most cells are about 4% to 8% efficient.Amorphous silicon cells can degrade on exposure to sunlight.
Amorphous silicon is much easier to make than grown silicon crystals, and by using several layers, each set for a different band gap “tuned” to a different part of the spectrum, a greater part of the visible spectrum can be used.Semiconductors copper indium diselenide (CuInSe2) and cadmium telluride (CdTe) are also used to manufacture solar cells. NREL researchers were able to attain an efficiency of copper indium diselenide with added gallium (sometimes known as “CIGS”) devices of between 18.1% and 18.8%.(120) Cadmium telluride cells operate at about 10% efficiency.
- Plastic solar cells
The work using dye-sensitive coatings was a step in the direction of cheaper solar cells. If the cells could be made entirely from plastic, there is hope that they will become a lot cheaper. One step in that direction was made by a group at Berkeley, which developed solar receptive materials of plastic nanotubes.It could even be possible to paint the surface of a roof with the plastic rods or have them attached to plastic sheets that could be attached to the roof surface and have the roof become a gigantic cell.
In its first incarnation, the efficiency is low, in the neighborhood of 1%, but the promise of cheap solar cells is enticing.
- Organic solar cells
The investigation of thin film organic photovoltaic materials has shown some promise.These materials are attractive to manufacturers, because they (presumably) could be sprayed onto their substrates similar to other films. This could allow increased manufacturing throughput. In addition, organic materials can take on a variety of colors easily. Some theoretical progress has been made, but many open questions remain.The efficiency of current thin organic films is mostly around 1%, but several examples of 2% efficiency were found.
