What Does Photoelectrochemistry Mean?

Photoelectrochemistry refers to a scientific field of study that evaluates the relationship between light and electrochemical systems, including the corrosion that occurs on a metallic surface that is exposed to sunlight.

The field of photoelectrochemistry plays a role in safeguarding metallic structures that are installed outdoors with periodic or regular exposure to ultraviolet (UV) sunlight emissions.

Corrosionpedia Explains Photoelectrochemistry

Empirical investigations have shown that a relationship exists between light and electrochemical cells, which in turn affects the corrosion rate. In particular, ultraviolet light accelerates the corrosion of metallic surfaces.

Metals that corrode faster due to sunlight can be stabilized to reduce corrosion by using a sacrificial anode or secondary metal.
