what is sollar cell?

Answer 1

it is a cell which convert sollar energy into electrical energy

Answer 2

Dear Friend,
As it seems the answers are being copied and pasted from sites like wikipedia, i would advice u to visit the site, www.wikipedia.com.
As far as the answer to u r question goes, A simple Solar Cell is a not much different than a normal pencil cell u use. A normal AA size cell converts the chemical energy stored in them into Electric current when ever required. The same is the case with the solar cell, whenever there is an incident solar radiation on the solar cell, due to photoemmisivity(emission of electrons by some materials when light is incident on them) electric current flows in a closed circuit.
The voltage rating of a sigle cell would be about 0.7V-3V.

Answer 3

A cell (battery) made to produce energy from sunlight. There are windmills that works with wind force rotating the fans. Like this, Solar Cells draw the sunlight and produce energy - electricity and stores them for future use. Normally, we can use this electricity for the night-lightign of home.

Answer 4

RAM could be powered by a solar cell, but, no, it could not produce a solar cell. The first answerer had a very good suggestion - one that plagues laptop computers much more than desktops - simply how to keep the CPU from collapsing under its own heat.

Answer 5

A solar cell produces voltage when the sun shines on it, the voltage is used to charge a ni-cad battery. Common use is an array of them to power a telephone in remote areas ! also heaps and heaps of other things including motor cars !!!

Answer 6

it is a cell which is carried easily by sun light

Answer 7

A solar cell (or a "photovoltaic" cell) is a device that converts photons from the sun (solar light) into electricity. In general, a solar cell that includes the capacity to capture both solar and nonsolar sources of light (such as photons from incandescent bulbs) is termed a photovoltaic cell. Fundamentally, the device needs to fulfill only two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics.

Solar cells have many applications. Historically solar cells have been used in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth orbiting satellites or space probes , consumer systems, e.g. handheld calculators or wrist watches, remote radiotelephones and water pumping applications. Recently solar cells are particularly used in assemblies of solar modules (photovoltaic arrays) connected to the electricity grid through an inverter, often in combination with a net metering arrangement.
The term "photovoltaic" comes from the Greek φώς:phos meaning "light", and the name of the Italian physicist Volta, after whom the volt (and consequently voltage) are named. It means literally of light and electricity.

The photovoltaic effect was first recognised in 1839 by French physicist Alexandre-Edmond Becquerel. However, it was not until 1883 that the first solar cell was built, by Charles Fritts, who coated the semiconductor selenium with an extremely thin layer of gold to form the junctions. The device was only around 1% efficient. Russell Ohl patented the modern solar cell in 1946 (US2402662, "Light sensitive device"). Sven Ason Berglund had a prior patent concerning methods of increasing the capacity of photosensitive cells. The modern age of solar power technology arrived in 1954 when Bell Laboratories, experimenting with semiconductors, accidentally found that silicon doped with certain impurities was very sensitive to light.

This resulted in the production of the first practical solar cells with a sunlight energy conversion efficiency of around 6 percent. This milestone created interest in producing and launching a geostationary communications satellite by providing a viable power supply. Russia launched the first artificial satellite in 1957, and the United States' first artificial satellite was launched in 1958. Russian Sputnik 3 ("Satellite-3"), launched on 15 May 1957, was the first satellite to use solar arrays. This was a crucial development which diverted funding from several governments into research for improved solar cells.

Simple explanation

1. Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon.
2. Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. The complementary positive charges that are also created (like bubbles) are called holes and flow in the direction opposite of the electrons in a silicon solar panel.
3. An array of solar panels converts solar energy into a usable amount of direct current (DC) electricity.

Optionally:

1. The DC current enters an inverter.
2. The inverter turns DC electricity into 120 or 240-volt AC (alternating current) electricity needed for home appliances.
3. The AC power enters the utility panel in the house.
4. The electricity is then distributed to appliances or lights in the house.
5. The electricity that is not used will be recycled and reused in other facilities.
