Our current research aims at developing high-efficiency, robust and scalable solar water splitting technology based on photoelectrochemical cells in tandem with photovoltaic cells. Toward this end, we study Earth abundant materials such as iron oxide (hematite, α-Fe2O3) and use thin film deposition techniques that are widely employed in the microelectronics and optoelectronics industries. In order to solve fundamental material challenges such as slow mobility and fast charge recombination we undertake a multidisciplinary and interdisciplinary research program that goes all the way from trying to understand the basic physics and chemistry of semiconductor photoelectrode / liquid electrolyte junctions to innovative device architectures for high efficiency tandem cells. We investigate how material structure, composition and defects influence charge transport properties and charge transfer dynamics using state-of-the-art facilities (see FACILITIES page). We develop innovative device architectures designed for optimal optical and electrical coupling of our photoelectrodes with photovoltaic cells for co-generation of electrical power and hydrogen fuel. We collaborate with leading researchers from the Technion and other universities in Israel, Europe, the USA and South Korea.
