Photochemistry is a branch of chemistry that studies the chemical effects of light. It is used to describe a chemical reaction that occurs when a substance's molecules absorb light energy. This reaction causes the molecules to experience a temporary excited state, which alters their physical and chemical properties. 
Some examples of photochemical reactions include: Photodissociation, Photosynthesis, Photosensitized reactions. 
Photochemistry is also important for the development of sustainable energy sources. Photochemical systems that use sunlight to generate electricity or drive chemical reactions are being studied. 
Some types of photochemistry include: Isomerization, Phosphorescence.
