How Solar Cells Work

PV solar panels work with one or more electric fields that force electrons freed by light absorption to flow in a certain direction. This flow of electrons is a current, and by placing metal contacts on the top and bottom of the PV cell, we can draw that current off for external use. This current, together with the cell''s voltage (which is a

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.
