Solar energy doesn’t pollute the earth.
Photovoltaic cells and thermal conversion are the methods available for converting solar power to electricity. Another way to generate electric power is using sunlight to create heat. This method is known as solar thermal conversion. Photovoltaic conversion uses sheets of a specialized material that can create electricity directly from the sun.
Sunlight is necessary to solar conversion as the name implies. (solar) This also uses reflectors and mirrors to create large amounts of heat from exposure to the sun. (Thermal energy is a type of energy). If you have ever starting a magnifying glass fire, than you were using solar energy. The magnifying glass lens concentrates the suns rays to create a pinpoint of intense heat. Actual solar cells used to store heat use this method to superheat liquids that produce steam. Steam is created, which in turn moves a turbine that converts the energy into electrity.
Light converted to electricity is the definition of Photovoltaic Conversion. Photovoltatic cell comprise panels made of two layers which are not made of the same stuff. One layer becomes positively charged and the other negatively when light hits them. Electric current is produced, when a ositive end and a negative end, when a wire connects the two ends, it produces very much like a regular battery. An electric current is created when the two layers of material in a solar cell are exposed to light.
Just one solar cell will of course work better when the sun is shining. The best results come from prolonged, intense, and direct sunlight.
These days you can find many different products that are solar powered. Solar power offers many benefits including the fact that it can be portable, and that it protects the earth. As was already pointed out, anyone who ever lit a campfire by holding up a magnifying glass has already put solar energy to work for them. The devices offered today are more efficient and effective then ever before. In the future it is extremely bright and promising the use of solar power now.
