PbS QD sensitized Ln-up-conversion improving water splitting performance of WO3/Si heterostructure under solar light
Project goal: This project optimizes photocatalytic water splitting by enhancing solar energy absorption. It improves Si photoelectrode stability, develops PbS QD-sensitized UCNPs to convert 1200-1500nm photons to visible light, and integrates them with Si heterostructure for better PEC efficiency and stability.
Project description: The project builds a device using PdS QD-UCNPs to shift NIR (1100-1500 nm) to visible light and a Si photoelectrode to convert visible photons (300-1100 nm) to hydrogen.
