An Article on Solar cell

A solar cell, also known as a photovoltaic cell, is any apparatus that directly transforms light energy into electrical energy using the photovoltaic effect. The vast majority of solar cells are made of silicon, which can be found in amorphous (non crystalline), polycrystalline, and crystalline (single-crystal) forms, with varying degrees of efficiency and cost. Solar cells do not use chemical reactions or require fuel to generate electricity, making them unlike batteries or fuel cells. They also do not have any moving parts, making them unlike electric generators.

Large clusters of solar cells known as arrays can be created. These arrays, which are made up of thousands of individual cells, can serve as central electric power plants by using solar radiation to produce electricity that can then be distributed to customers in the industrial, commercial, and residential sectors. On their rooftops, homeowners have installed solar cells in much smaller designs, often known as solar cell panels or just solar panels, to supplement or replace their traditional energy supply. Solar cell panels are also employed to produce electricity in numerous distant terrestrial regions where conventional electric power sources are either unavailable or excessively expensive to build.

Most space facilities, from communications and weather satellites to space stations, are powered by solar cells since they don't have any moving parts that might need maintenance or fuels that?need to be refilled. However, due to the spread of radiant energy with increasing distance from the Sun, solar power is insufficient for space probes deployed to the outer planets of the solar system or into interstellar space. Consumer devices including electrical toys, pocket calculators, and portable radios have all utilized solar cells. Such gadgets' solar cells may use natural and artificial light from the sun, such as incandescent and fluorescent lamps.
