What is a Solar Cell?
A solar cell is a device that converts light energy – typically from the sun – into electricity through the photovoltaic effect. Solar cells are made from semiconductor materials, primarily silicon, which absorb sunlight and release electrons that generate a direct electric current. These cells are the fundamental building blocks of solar panels, which are widely deployed in solar power systems across the world.
The primary production method spans silicon extraction, purification, wafer cutting, cell formation, module assembly, and testing. Solar cells are assembled into modules and deployed across a wide range of applications including home rooftop solar panels, large-scale solar power plants, solar-powered vehicles, energy storage systems, and portable solar devices. The product serves end-use industries including residential power generation, commercial and industrial energy supply, off-grid energy solutions, electric vehicles (EVs), and agriculture.
