One of the paramount challenges for a sustainable society is the conversion of solar energy into a vector suitable for storage and transport. Solar energy can be stored with battery technology by converting it into electricity via photovoltaic (PV) cells; however, producing H2 fuel via photoelectrochemical (PEC) water splitting is a more efficient solution for long-term storage. In this talk, I will present an overview on solar to hydrogen conversion technologies including PEC and photocatalytic water splitting, as well as PV + electrolysis by comparing the strengths and weaknesses of each technology. Particularly, more details in fundamentals, research trends and future perspectives in PEC water splitting will be discussed. One major research stream in the field of PEC water splitting is to search cost-effective light absorbing semiconductors having promising properties. Other research areas, such as fabrication of high-performance devices and some advanced characterization methods for PEC water splitting devices will also be covered. |
