Photochemistry
Photochemistry is the branch of chemistry concerned with the chemical effects of light, involving the absorption of photons by molecules to initiate chemical reactions or physical changes. It studies processes like photolysis, photosynthesis, and photopolymerization, which are fundamental in fields ranging from materials science to biology. This concept underpins technologies such as solar energy conversion, photodynamic therapy, and photographic development.
Developers should learn photochemistry when working on applications involving light-sensitive materials, renewable energy systems (e.g., solar cells), or biomedical devices (e.g., light-activated drugs), as it provides the theoretical basis for designing and optimizing these technologies. It is essential for roles in chemical engineering, environmental science, or any domain where light-driven processes are critical, such as in developing advanced sensors or sustainable manufacturing methods.
