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. Solar PV systems generate electricity by absorbing sunlight and using that light energy to create an electrical current.
