So, this is a material that produces electricity when light shines on it. A solar cell does the exact same thing only this uses a chemical reaction instead of the "photoelectric effect" which is a product of quantum mechanics.
How do these two things compare in efficiency now and what are the theoretical and practical limits to this new "spinach engine"?
