What is Photovoltaic Effect?

Photovoltaic Effect Definition

The photovoltaic effect is the direct conversion of light energy to electrical energy using semiconductor materials.

Semiconductor Role

Semiconductors like silicon are crucial as they facilitate the movement and interaction of electron-hole pairs necessary for electricity generation.

Charge Carrier Dynamics

The movement of electrons and holes across the semiconductor junction is essential for establishing an electric field that aids in electricity generation.

Impact of Sunlight

Exposure to sunlight energizes electrons in silicon, leading to the creation of electron-hole pairs and subsequent electrical current.

Efficiency Factors

Solar cell design aims to maximize the separation of electron-hole pairs to increase the efficiency of electricity generation.
