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…
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…
Wavelength Dependent Photocurrent of Hematite Photoanodes: Reassessing the Hole Collection Length
Asaf Kay, Daniel A Grave, Kirtiman D Malviya +3
The photoelectrochemical behavior of a planar 1 cm2 thick Ti-doped hematite film deposited on F:SnO2 coated glass was studied with both front and back illumination. Despite low qua…
Implementing strong interference in ultrathin film top absorbers for tandem solar cells
Yifat Piekner, Hen Dotan, Anton Tsyganok +4
Strong interference in ultrathin film semiconductor absorbers on metallic back reflectors has been shown to enhance the light harvesting efficiency of solar cell materials. However…
Magnetic states at the surface of alpha-Fe2O3 thin films doped with Ti, Zn or Sn
David S. Ellis, Eugen Weschke, Asaf Kay +6
The spin states at the surface of epitaxial thin films of hematite, both undoped and doped with 1% Ti, Sn or Zn, respectively, were probed with x-ray magnetic linear dichroism (XML…
