Interfacial Layer/Overlayer Effects in Photoelectrochemical Water Splitting
Rohit Shrivastav, Gurpreet Kaur, Divya, Vibha R Satsangi and Sahab Dass
Aiming to gain increments in conversion efficiency, several new and innovative thoughts have been embedded in recent years to the ongoing research on photoelectrochemical splitting of water. In this context, photoelectrodes with nanoheterostructred configurations, evolved through overlayer/interfacial layer of different semiconductors, hold high promise. The approach facilitates simultaneous use of more than one low-cost and earth-abundant material in the photoelectrode design. It has emerged as an effective strategy not only to widen wavelength-range for light-absorption but also to reduce recombination losses by faster separation and swift migration of photogenerated electrons/holes. This chapter presents this specific aspect of hydrogen generation by photoelectrochemical water splitting.
