Here's my stupid idea: It's my understanding that plants only respond to a fairly narrow band of light, somewhere between 400 nm and 700 nm wavelengths. All the other solar energy is more or less wasted on them. Could we have a solar panel that collected energy from a wide range of light wavelengths, and then used that energy to create light that is concentrated mostly in the 400-700nm range, thereby possibly giving a > 100% efficiency from the perspective of plant growth.
