How efficient are our best solar panels compared to the leaves of plants at converting solar energy?
gpt
Plants usually have an efficiency around a few percent while the best laboratory devices have an efficiency of over 40%. A commercial solar cell will probably be closer to 10%. So in conclusion even a "bad" solar cell will usually be better at extracting useful energy from sunlight than plants.
