Solar cell

A photo voltaic cell (solar cell) is a device which converts light energy into electric energy.when light is made to fall on this cell ,the voltage across its terminals increases.The value of voltage increases with the increase of intensity of incident light.The photo-voltaic cell is basically a junction device.The cells are made of semi-conductor materials.It is generally made from either silicon or selenium.
