(Invited) Computational and Experimental Studies of Solar Water Splitting Technologies

Abstract

Solar water splitting technologies are attractive in that intermittent solar energy is directly converted to hydrogen as economically scalable energy storage. In this presentation, we will overview various types of solar water splitting such as III-V, chalcopyrite, and nano particle based z-scheme where trade offs unique to each technologies will be discussed. While remedies will be also unique to the technology, there are some common factors in the approaches. These differences and commonality will discussed based on our own experiences in the past 12 years. Part of this work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
