How do solar cells work? Photovoltaic cells explained

A solar module comprises six components, but arguably the most important one is the photovoltaic cell, which generates electricity.The conversion of sunlight, made up of particles called photons, into electrical energy by a solar cell is called the "photovoltaic effect" - hence why we refer to solar cells as "photovoltaic", or PV for short.

How Do Solar Panels Work? Solar Power Explained

Concentrated solar power. Concentrated solar power (CSP) works in a similar way to solar hot water in that it transforms sunlight into heat—but it doesn''t stop there. CSP technology concentrates the solar thermal energy using mirrors and turns it into electricity. At a CSP installation, mirrors reflect the sun to a focal point.
