Solar Power Unit

We have started a solar power unit. You use the kits to create objects that run on electricity that is generated by the solar cells. As you may have found out the light inside the room is not strong enough to power the cells, so you must go outside to the sunlight.
The solar cells take the sunlight and absorb it, which creates a flow of electrons inside the cells. These electrons flow out through the wires to the motor. The flowing through the wires in the motor generate a magnetic field. The magnetic field pushes the axle that runs through the motor. This is how the motor works.
I wonder if we could find a way to hook up your brains to a solar cell. That way we could have class outside and the brighter the sunlight, the brighter you would be.
