Solar panels are an increasingly popular form of renewable energy.
A research team at Stanford University is working to solve the problem of bulky batteries and dark hours.
The atmosphere around the cell is warmed by a new heat source: Earth.

Our planet absorbs heat from the sun during the day, which is later radiated back to space.
This is a much higher energy level than other efforts to capture energy at night.
