Stanford engineers have figured out a new way to make solar panels that use both the sun’s light and heat to generate energy. It’s a discover that could double the efficiency of solar panels.

With today’s photovoltaic panels, as the sun heats them up, they get less efficient. They can’t use the heat to generate energy, just the light. And as their temperatures reach 100 degrees Celsius, they stop working altogether.

But by coating a piece of semiconducting material with a thin layer of the metal celsium, it allows the panels to use both light and heat to gather juice.
