| Abstract |

Semiconductor materials hold the key for efficient photocatalytic and photoelectrochemical water splitting. In this talk, we will give a brief overview of our recent progress in designing semiconductor nanomaterials for photoelectrochemical energy conversion including solar hydrogen generation and solar cells. In more details, we have been focusing on a couple of aspects; 1) photocatalysis mechanism, light harvesting, charge separation and transfer and surface reaction engineering of low-cost oxide based semiconductors including TiO2, BiVO4 as efficient photoelectrode for photoelectrochemical hydrogen production, 2) the working mechanism and stability improvement of perovskite quantum dots for both high efficient solar cells and photocatalytic hydrogen, 3). the design of ultra-stable composites of perovskite-MOF with improved PLQY.1-8 The resultant material systems exhibited efficient photocatalytic performance and improved conversion efficiency in solar cells, which underpin sustainable development of solar-energy conversion application.
