Ruthenium Oxide Hydrogen Evolution Catalysis on Composite Cuprous Oxide Water-Splitting Photocathodes

Michael Graetzel, Morgan Mertens Stefik, Stanley David Tilley, Marcel Roland Schreier

Photocathodes based on cuprous oxide (Cu2O) are promising materials for large scale and widespread solar fuel generation due to the abundance of copper, suitable bandgap, and favorable band alignments for reducing water and carbon dioxide. A protective ove ...

Wiley-Blackwell2014

Solar energy represents an abundant (1000 W·m-2) and seemingly cheap source of energy. One way to tap it is to transform light into electricity with photovoltaic devices. Single junction solar cells presently reach 32% conversion yield under 1-sun illumina ...
