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…
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…
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…
Photoelectrochemical water splitting in separate oxygen and hydrogen cells
Avigail Landman, Hen Dotan, Gennady E. Shter +5
Solar water splitting provides a promising path for sustainable hydrogen production and solar energy storage. One of the greatest challenges towards large-scale utilization of this…
