Photoelectrochemical solar fuel generation on hybrid photoelectrodes

We employ hybrid materials in photoelectrochemical cells to generate fuels. Our focus is on the reduction of CO2, thus we develop photocathode for this purpose, as well as photoanodes for the conjugate reaction (water oxidation). We aim to understand how the functions of individual components can be integrated into hybrid photoelectrodes, in a way so that the synergy can be fully harnessed.
