means The biological mechanisms organisms use to shield themselves from damaging light, especially UV radiation and excess sunlight that can wreck cells and molecules.

from A straightforward scientific compound: 'photo-' from Greek 'phos/photos' meaning light, joined to 'protection' from Latin 'protegere' — to cover in front, to shield. The term emerged in biology and chemistry writing as scientists needed a precise label for pigments, enzymes, and behaviors (like melanin production or leaf orientation) that guard living tissue from light-induced harm — no single coiner, just science naming what nature had already invented.
