How does solar power make electricity?

Question

Dont tell me the suns rays hit the solar panels and it makes electricity.

i need to know each step that happens when the rays hit the solar panel.

pls put in bullets

Answer 1

1.The solar gets the sun's rays
2.Heat is produced,inside the house there are pipe lines where the water is
3.Due to theheat coming from the sun it also heats up and creates steam(Steam is ahot wind)
4.The steam rotates the generator's turbines giving electricity

.357: Sunlight travels through space and reaches Earth in about 8 hours (if I remember that right from school) and strikes the panel.

.40 S&W: Then a photovoltaic (PV) or solar cell, there are two layers of silicon. Both are doped, or lightly mixed, with a certain element. Typically, one side is doped with boron and the other with arsenic.

9mm: Because of the way each element bonds to the silicon, the layer containing boron, called the n-type layer, has a surplus of free electrons.

10mm: The other side, the p-type layer, has a deficit of electrons. These deficits are called holes. The p-type layer and n-type layer are pressed closely against each other and linked by a wire connected to an external load. This creates a circuit in the solar cell.

.454 Casull: When sunlight of the right energy level hits the n-type layer, which is on top of the solar cell, it excites some of the free electrons, which break loose from their natural state -- pairs -- and flow across the boundary between the layers to create a current.

.45 Auto: This only works if the two layers of the solar cell are pressed directly into each other. This is usually accomplished by fabricating both sides as part of the same process.

.380: The current flows through the p-layer into the wire, which goes to the load, generally used to store electricity. The current is DC. If an AC current for household appliances is desired, the DC current is put through an alternator.

.308: After flowing through the load, the current continues back into the n-layer, which is lacking in electrons in some areas due to the current. The process continues. A current is generated without any mechanical input. This is the magic of the solar cell. Unfortunately, a solar cell can be quite expensive.

.30-30: For protection, the top layer of the solar cell is covered with a glass plate affixed with transparent resin. The entire setup is called a p-n junction diode. More sophisticated solar cells use a series of p-n junction diodes.

.45-70: The first solar cells were only 1% efficient. Today, commercial solar panels are between 5% and 15% efficient. There are currently millions of dollars going into research on improving these percentages.

Unfortunately, I couldn't use real bullets. But I hope this helps!

Answer 3

A summery of what i was told in my construction class. The light from the sun (solar) come down and hits the solar panel enters though a panel that is a blueish tent which acts as a filter. then when the beam enters into the panel there is something inside of the panel that separates the electrons in the beam and cause they are a heavy material they fall down then go though a hole at the bottom causing a charge to occur and then release and that is a summary of how a solar panel produces power.

Answer 4

The photons cause the electrons in the top layer of the cells to become excited and eventually move throught the gap between the two layers.

Or, the sun heats water or some other coolant type substance and this is used in a heat exchanger to produce energy.

Answer 5

Photons from the sun, if of sufficient energy can elevate an electron in a semiconducting material such as silicon from the normal ground state to a higher level, from which a direct drop back to the ground state (with emission of radiation) is forbidden by the laws of quantum mechanics. These electrons are collected by conductive strips, passed through an external circuit to do work, and returned to the material which they re-enter in the ground state. And that's the physics.

Answer 7

The 2 methods are photovoltaics and steam generation.
Silicon produces a voltage when sunlight falls on it. solar panels take a bunch of silicon cells together, adding their voltages,giving useful voltages.
Sunlight is focussed by mirrors onto a pipe containing water.it boils to produce steam,which is used to spin a turbine to produce electricity..

Answer 8

Solar cells, also referred to as photovoltaic cells, are devices or banks of devices that use the photovoltaic effect of semiconductors to generate electricity directly from sunlight. Until recently, their use has been limited because of high manufacturing costs. One cost effective use has been in very low-power devices such as calculators with LCDs. Another use has been in remote applications such as roadside emergency telephones, remote sensing, cathodic protection of pipe lines, and limited "off grid" home power applications. A third use has been in powering orbiting satellites and other spacecraft.

Answer 9

photograph voltaic is extra suitable because of fact it makes use of the sunlight rather of fossil fuels to offer electricity. It has many disadvantages, although. that's no longer very solid like skill from the electrical powered grid because of fact in many factors that have loads of cloudy days it does not artwork nicely, and of direction does not artwork at night. It additionally takes an somewhat super floor element of panels to offer lots skill because of fact the capability from the sunlight is somewhat little for each sq. foot of floor. The disadvantages stress the cost of photograph voltaic skill installations up so severe that maximum folk can't cope with to pay for it because of fact prevalent skill is so low-value whilst in comparison with it.

Answer 10

Sun is the source of energy.Most energy sources are ultimately derived from solar energy. Most governments offer several incentives to producers and users of alternative energy sources. Pleasevisit http://altenergy.in/
