The GaAs/GaInP2 PV/PEC tandem cell has shown to be a high-efficiency water splitting system, but this material system has not shown the necessary long-term stability and interfacial catalysis and energetics are still an issue. Stabilizing the system using surface treatments or solution additives has improved the stability but band-edge energetics and surface catalysis are still important challenges.This report will discuss our recent results in modifying the band-edge energetics and attaching homogenous catalysts for hydrogen evolution.
