Abstract:

Semiconductor nanomaterials hold the keys for efficient solar energy harvesting and conversion processes like photocatalysis and photoelectrochemical reactions. In this talk, we will give a brief overview on our recent progress in designing semiconductor nanomaterials for photoelectrochemical energy conversion including solar hydrogen generation and low-cost solar cells. In more details, we have been focusing on a few aspects; 1) artificial photosynthesis reaction mechanism, light harvesting, charge transfer and surface reaction engineering of low-cost semiconductors for solar driven hydrogen and valuable chemical production; 2) the working mechanism and stability improvement of perovskite quantum dots and lead-free tin-based perovskite solar cells; 3). The design of ultra-stable perovskite-MOF composites with improved light emitting performance and photocatalysis. The resultant material systems exhibited efficient photocatalytic performance for value-added chemical production and improved power conversion efficiency in solar cells, which underpin sustainable development of solar energy conversion technologies towards carbon neuralization.
