Photosynthetic efficiency is bounded not by genetics alone but by fundamental thermodynamics: sunlight spans wavelengths unusable by chlorophyll and carries entropy that cannot be fully converted to chemical work.
Only photons between 400–700 nm (PAR) drive electron transport; infrared photons lack energy to excite electrons, while UV photons waste excess energy as heat.
