What is the working principle of a solar cell?
Working Principle: The solar cell working principle involves converting light energy into electrical energy by separating light-induced charge carriers within a semiconductor. Role of Semiconductors: Semiconductors like silicon are crucial because their properties can be modified to create free electrons or holes that carry electric current.
Why do solar cells use semiconductors?
They use semiconductors as light absorbers. When the sunlight is absorbed, the energy of some electrons in the semiconductor increases. A combination of p-doped and n-doped semiconductors is typically used to drive these high-energy electrons out of the solar cell, where they can deliver electrical work before reentering the cell with less energy.
How does a photovoltaic cell work?
Photovoltaic Cell Defined: A photovoltaic cell, also known as a solar cell, is defined as a device that converts light into electricity using the photovoltaic effect. Working Principle: The solar cell working principle involves converting light energy into electrical energy by separating light-induced charge carriers within a semiconductor.
