Write the Fundamental Principle of a Photo - Voltaic Energy Conversion Process.
These materials, called semiconductors, have special properties that allow them to generate electric current when exposed to light. When sunlight hits the surface of a photovoltaic cell made of these semiconductors, it excites electrons in the material, causing them to move and create an electric current.
This current can then be captured and used as electrical energy. This process, known as the photovoltaic effect, forms the basis of solar panels and enables the conversion of sunlight into usable electricity without the need for mechanical or chemical reactions.
