Perspectives of Group III-Nitride Material for Photoelectrocatalysis

The potential and the physical properties of group III-nitride compound semiconductors will be discussed in the context of photoelectrocatalytic solar fuel structures. The band alignments in the ternary InGaN alloy system with respect to potential catalysts HOMO and LUMO states are assessed regarding the efficient charge transfer in photoelectrochemical cell structures. The presentation will also present the current status in group III-nitride materials fabrication and ternary alloy formation, their stabilization and integration into envisioned materials structures, together with challenges that have to be addressed to enable the full potential of group III-nitrides to contribute to high-efficient energy conversion.
