Activity.... Do - Think
We can use the energy from the sun to make electricity. Solar cells are used to convert the solar energy from the sun into electricity.
Move the arm on the exhibit and press to connect up to the solar cell.
When does the solar cell work best?
Do solar cells work at night?
What other ways can you make electricity on this exhibit?
 
The Science Bit
A solar cell is also known as a photovoltaic cell. In the cell electrons flow when light hits the surface of a semiconductor material. This flow of electrons produces an electric current.
Even on cloudy days electricity is produced. On sunny days any spare energy can be stored in a special type of battery to be used when needed.
