...he silicon surface. When photons from the sun's rays hit the silicon surface of a solar cell, they are absorbed by the electron of the silicon atom. The supercharged electron now has enough kinetic energy to leave the host atom. The solar cell collects the stream of liberated electrons on its surface, ...Advances in plasma physics at Annual APS Meeting

Today the skin-ageing effects of ultraviolet (UV) rays are well known, but the harmful consequences of air pollution on our skin are less easily quantified outside of laboratories.
