3. HOW IS SOLAR ENERGY CONVERTED INTO USABLE ELECTRICITY?

Solar energy conversion into electricity primarily occurs through the photovoltaic (PV) effect in solar panels. When sunlight strikes the solar cells, it excites electrons within the material, creating an electric current. This process occurs inside silicon-based solar cells, the most commonly used type in modern solar panels.

The basic structure of a solar cell includes two layers of silicon; one layer is doped with phosphorus (n-type) to create an abundance of free electrons, while the other layer is doped with boron (p-type) to create “holes” with a positive charge. When light hits the cells, electrons move through the cell, generating direct current (DC). An inverter then converts this DC into alternating current (AC), the form of electricity usable in homes and businesses.

The energy produced by solar panels can subsequently feed into the grid, charge battery storage systems, or power various electrical appliances directly. Continuous advancements in photovoltaic technologies may improve efficiencies further and expand the capabilities of solar energy as a sustainable energy source.
