Abstract

Hybrid photoanodes for water-splitting photoelectrochemical cells (WS-PECs) consist of a visible-light-absorbing semiconductor (VLASC) with a molecular water-oxidation catalyst (mWOC) attached and show great promise for solar fuel generation. In this Perspective, we will focus on the less emphasized but crucial subject of stability in these systems. The stability of each component, including the VLASC, the mWOC, and the connection of the two, must individually be considered, as well as how the system functions as a whole. We offer design strategies for each of these parts, as well as some characterization techniques helpful in the study of degradation. Finally, we propose some future directions for the development of hybrid WS-PEC photoanodes with long-term stability that could be suitable for practical application.
