Solar batteries are very convenient things. They are great sources of power when electricity is not available. For this reason hikers and trekkers often use solar batteries and chargers to charge their torches and other appliances. There are available batteries for even charging dead car batteries. Though it takes a lot of time to charge a car battery using a solar charger this is an invaluable option in remote places where it is difficult to find resources and even other cars to jump the batteries.
Here is some information on solar batteries. Solar batteries work on the basic principle that when electromagnetic rays from the sun hit certain substances thy emit ions which are used as sources of electricity. These substances are usually silicon semiconductors which absorb some of the radiation from the sun. While doing this they release some electrons and this flow of electrons is an electric current. A photovoltaic cell which is another name for a solar battery does not carry pure silicon though but also boron and phosphorous put in on purpose to increase the output of electricity.
Solar batteries take a lot of time to charge and do not get charged unless there is some sun. But still they are useful in saving electricity bills. They are also one of the best green appliances invented as by saving electricity they help to save the earth’s resources and cut down on pollution.
Solar batteries can be used on a lot of electrical device like cell phones, mp3 players and laptops. Solar batteries are also used to power garden lights and street lights.
