Photoelectrolysis

Photoelectrolysis is a big word that means using light to split water into two different chemicals called hydrogen and oxygen. Imagine you have a glass of water with a straw in it. Now imagine you shine a flashlight on the water. The light from the flashlight carries something called energy. This energy can be used to break apart the water molecules into tiny pieces. When we do this with the water in the glass, the energy in the light makes the water turn into tiny bubbles of oxygen and hydrogen. These bubbles float up and out of the glass. This is what photoelectrolysis does too, except it uses special materials that are good at turning light into energy. This helps us make hydrogen fuel that's clean and can be used to power things like cars and even buildings. So, photoelectrolysis uses light to split water into two important chemicals that can help us make fuel.
