Film flip and transfer process to enhance light harvesting in ultrathin absorber films on specular back-reflectors
Asaf Kay, Barbara Scherrer, Yifat Piekner +4
Optical interference is used to enhance light-matter interaction and harvest broadband light in ultrathin semiconductor absorber films on specular back-reflectors. However, the hig…
Defect segregation and its effect on the photoelectrochemical properties of Ti-doped hematite photoanodes for solar water splitting
Barbara Scherrer, Tong Li, Anton Tsyganok +11
Optimising the photoelectrochemical performance of hematite photoanodes for solar water splitting requires better understanding of the relationships between dopant distribution, st…
The rust challenge -- On the correlations between electronic structure, excited state dynamics and photoelectrochemical performance of hematite photoanodes for solar water splitting
Daniel A. Grave, Natav Yatom, David S. Ellis +2
In recent years, hematite potential as a photoanode material for solar hydrogen production has ignited a renewed interest in its physical and interfacial properties, which continue…
Different roles of Fe1-xNixOOH co-catalyst on hematite (α-Fe2O3) photoanodes with different dopants
Anton Tsyganok, Dino Klotz, Kirtiman Deo Malviya +2
Transparent Fe1-xNixOOH overlayers (~2 nm thick) were deposited photoelectrochemically on (001) oriented heteroepitaxial Sn- and Zn-doped hematite (Fe2O3) thin film photoanodes. In…
Empirical Analysis of the Photoelectrochemical Impedance Response of Hematite Photoanodes for Water Photo-Oxidation
Dino Klotz, Daniel A. Grave, Hen Dotan +1
Photoelectrochemical impedance spectroscopy (PEIS) is a useful tool for the characterization of photoelectrodes for solar water splitting. However, the analysis of PEIS spectra oft…
The spatial collection efficiency of photogenerated charge carriers in photovoltaic and photoelectrochemical devices
Gideon Segev, Hen Dotan, David S. Ellis +7
The spatial collection efficiency portrays the driving forces and loss mechanisms in photovoltaic and photoelectrochemical devices. It is defined as the fraction of photogenerated…
