Changing Solar Energy Become Electrical Energy

Solar energy is a source of enormous energy in the world. Solar energy has the potential to provide the world's energy needs for a long time if it is used as much as possible. Direct utilization of solar energy can be used to heat up or refrigerate.

One of the utilization of solar energy is solar thermal power plants. The mechanism used is the large glass that is used to concentrate sunlight into a single line or point. Heat is captured, harnessed to produce steam. High pressure steam is used to run turbines to produce electricity.

In addition to the vapor pressure of the heat, sunlight can be utilized as a source of electricity using photovoltaics. The principle involves photovoltaic electricity generation of light, the use of semi-conductor materials that can be adapted to release electrons (negatively charged particles) that create electricity.

Semi-conductor materials most commonly used is silicon. Photovoltaic cells have at least two layers of semi-conductors, the first layer is Positively charged and negatively charged layer of a second. When light shines on the semi-conductor, an electrical charge across a Connection Between the two layers Causes electricity to flow, generating DC current.

Moreover to utilizing the heat to generate electricity, a research team from MIT is developing the different energy storage technologies. Utilization and molten salt batteries are still used today as an energy storage medium. Utilization and molten salt batteries are still used today as an energy storage medium.

The team was utilizing nano technology which is a key technology of energy storage media. Azobenzena are the names of the carbon tube that will make the technology as a solar battery. This battery has a different principle with regular batteries. Regular battery converts chemical energy into electrical energy, but batteries store solar heat in the battery container and turn heat to chemical energy stored in the which the container is sealed from the outside and the water temperature.At the time needed, the stored thermal energy can be recovered.

Azobenzena in solar battery capable of producing the equivalent energy density of lithium ion. In fact, the batteries are being developed that can be constantly refilled and used in a long time.
