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.
Photovoltaic effect in various semiconductor junctions and interface. The PV effect is a key to solar energy conversion, where electricity is generated from light energy. Owing to quantum theory, light is regarded as packets of energetic particles called photons, whose energy depends only on light frequency.
Solar Cell Definition: A solar cell (also known as a photovoltaic cell) is an electrical device that transforms light energy directly into electrical energy 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. Role of Semiconductors: Semiconductors like silicon are crucial because their properties can be modified to create free electrons or holes that carry electric current.
Working Principle: The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.
The solar cell is an example of a photovoltaic cell. This type of cell is often referred to as a PV cell, which is an abbreviation for “photovoltaic cell.” A solar cell is composed of its most fundamental component, a diode with a p-n junction.
