I will use a photoelectric sensor if I want to turn something on or off (when there is light around).
Say, if I want a street lamp to go on at night.
one is replacing a battery and the other is replacing a switch.
a plant leaf is the biological version of a solar cell, it gets lots energy from the sun and lets all the living creatures on earth use it in the form of food.
Your eye is similar to a photoelectric sensor ( but much more complicated )
as it basically conveys data rather than large amounts of energy.
