Arthur Nozik was a scientist who discovered something called the Quantum Theory of Solar Cells. This is an important scientific discovery that helps us understand how sunlight can be converted into electricity.
In simple terms, solar cells are like tiny energy machines. They take in energy from the sun and then turn it into electricity. This electricity can then be used to power things like our homes and businesses. By understanding how sunlight is turned into electricity, scientists like Arthur Nozik are helping the world have access to clean and renewable energy.
