Abstract

Mimicking natural photosynthesis, semiconductor photoelectrocatalysis (PEC) is a promising approach to directly convert and store renewable solar energy in the form of chemical bonds. Solar water splitting to produce hydrogen fuel is one of the most-studied examples for PEC. This chapter covers the fundamentals of three key steps of PEC: light absorption, charge separation and chemical catalysis, with an emphasis on the selection criteria of favorable material properties for semiconductor light-absorbers and electrocatalysts. Judicious integration of semiconductor and catalyst with desired energetics is key to optimizing both energy efficiency and operational stability obtained at solid/liquid interface. Prospects of integrated PEC devices for practical applications are also discussed based on recent developments.
