Photovoltaic cells are made of at least two layers of semiconducting material. The first layer has a positive charge; the next layer has a negative charge. When sunlight strikes the cell, the semiconducting material absorbs photons from the light. This process frees electrons from the negative layer, which move to the positive layer. This flow of electrons constitutes an electric current, which can be captured in a circuit connecting the two layers. The electricity generated by a photovoltaic cell can be used directly, stored in batteries or sold back to a utility company.

Solar energy comes from the lowest point of the sun.

August Mouchout is credited with the creation of the first active solar motor. In 1861, he developed a steam engine fueled completely by the sun.

Solar Energy comes from Sun.

1) Individual silicon based (most commonly) cells called photovoltaics (PV) make up the modern day solar panel. These PV cell clusters perform the task of converting incoming sunlight directly into electricity. 2) Wires attached to the panels transport the converted electricity to a piece of equipment called an inverter. The job of the inverter is to convert the solar generated Direct Current (DC) electricity into the type of power your home can use, which is called Alternating Current (AC). 3) After the electricity travels through the inverter, the AC electricity is then transported via wire to your breaker panel to meet your home’s electric demands. 4) The process doesn’t end there, though. There are times when your panels will generate more power than you consume and times when you aren’t generating enough electricity (night times and periods of low light). When your panels are not generating enough solar electricity, you will continue to get power from your local utility. However, when you’re generating a surplus of solar electricity, that excess clean energy will be “net metered” to your local utility grid and you may earn a credit on your power bill for that net metered electricity.

A solar cell is any device that directly converts the energy in light into electrical energy through the process of photovoltaics. The development of solar cell technology begins with the 1839 research of French physicist Antoine-César Becquerel. Becquerel observed the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution when he saw a voltage develope when light fell upon the electrode.

Solar energy is good for the planet because it is a clean way to produce things we need every day. It doesnt cause pollution because it is nature's own energy and is a 100% renewable resource.

solar energy is environmentally safe and does not contribute to pollution, acid rain, global warming, or smog. it is very dependable and lasts as long as the sun does-a couple billion years.

Solar energy is energy that is obtain from the sun. This can be found most common in lights and high tech watches.Solar energy does not work when the sun is not shinning.
