Solar Photovoltaic Cell Basics

harnessing sunlight for power

At the heart of every solar photovoltaic system lies the solar photovoltaic cell, a remarkable device that harnesses the power of light to generate electricity through the photovoltaic effect.

These cells are made from silicon, a semiconductor material that converts sunlight into electricity. When sunlight hits the cell, it knocks electrons loose, creating an electric current. The free electrons flow towards the positive side, generating electricity.

The output voltage of a solar cell is measured by its maximum voltage (VM) in volts. The power output depends on the sunlight received and the cell's angle to the light source.

Understanding the basics of solar photovoltaic cells is essential in designing and optimizing solar photovoltaic systems for efficient energy generation.
