Abstract
Three-terminal (3T) photoelectrodes with cathodic protection capability are described. The 3T photoelectrodes utilize the third (i.e., the 'extra') electrode to bypass the diode in a semiconductor circuit and pass current with significant reductions in corrosions or reverse bias. The 3T photoelectrodes may be operated in diode mode when exposed to illumination and switched to an ohmic mode when light is significantly reduced (i.e., in the dark) to enable cathodic protection. The 3T photocathodes may maintain photoelectrochemical (PEC) activity in methyl viologen electrolyte under light/dark cycling. The 3T photoelectrodes may enable PEC in conditions where variable illumination is a regular occurrence.
