Electrical, Photoelectrochemical, and Photoelectron Spectroscopic Investigation of the Interfacial Transport and Energetics of Amorphous TiO₂/Si Heterojunctions

Journal Article Hu, Shu ; Richter, Matthias H. ; Lichterman, Michael F. ; ... - Journal of Physical Chemistry. C

Solid-state electrical, photoelectrochemical, and photoelectron spectroscopic techniques have been used to characterize the behavior and electronic structure of interfaces between n-Si, n⁺-Si, or p⁺-Si surfaces and amorphous coatings of TiO₂ formed using atomic-layer deposition. Photoelectrochemical measurements of n-Si/TiO₂/Ni interfaces in contact with a series of one-electron, electrochemically reversible redox systems indicated that the n-Si/TiO₂/Ni structure acted as a buried junction whose photovoltage was independent of the formal potential of the contacting electrolyte. Solid-state current–voltage analysis indicated that the built-in voltage of the n-Si/TiO₂ heterojunction was ~0.7 V, with an effective Richardson constant ~1/100th of the value of typical Si/metal Schottkymore »« less

Photoelectrochemical energy conversion obtained with ultrathin organo-metallic-chemical-vapor-deposition layer of FeS[sub 2] (pyrite) on TiO[sub 2]

Journal Article Ennaoui, A ; Fiechter, S ; Tributsch, H ; ... - Journal of the Electrochemical Society; (United States)

Ultrathin (10 to 20 nm thick), polycrystalline films of FeS[sub 2] (pyrite) were grown on TiO[sub 2] (anatase) by chemical vapor deposition. The FeS[sub 2] films were characterized using optical absorption and high-resolution electron microscopy. Photoelectrochemical solar cells, using TiO[sub 2] (anatase) coated with FeS[sub 2] ultrathin films, generated high open-circuit photo-voltages, of up to 600 mV, compared with a single crystal of pyrite electrode (200 mV). The photoelectrochemical behavior shows a strong dependence of photovoltage and photocurrent on the pH of the solution. This paper reports that it is explained by electron injection from the conduction band of FeS[submore »« less

Failure modes of protection layers produced by atomic layer deposition of amorphous TiO₂ on GaAs anodes

Journal Article Buabthong, Pakpoom ; Ifkovits, Zachary P. ; Kempler, Paul A. ; ... - Energy & Environmental Science

Amorphous titanium dioxide (a-TiO₂) films formed by atomic layer deposition can serve as protective coatings for semiconducting photoanodes in water-splitting cells using strongly alkaline aqueous electrolytes. Herein, we experimentally examine the mechanisms of failure for p⁺-GaAs anodes coated with a-TiO₂ films (GaAs/a-TiO₂). Galvanic displacement of exposed GaAs by Au allowed imaging of pinholes in the a-TiO₂ coatings, and enabled collection of quantitative and statistical data associated with pinhole defects. A combination of imaging, electrochemical measurements, and quantitative analyses of corrosion products indicated that extrinsic pinholes were present in the a-TiO₂ films before electrochemical operation. During electrochemical operation these pinholes ledmore »« less

Photoelectrochemical water splitting and simultaneous photoelectrocatalytic degradation of organic pollutant on highly smooth and ordered TiO{sub 2} nanotube arrays

Journal Article Hongjun, Wu ; Institute of Basic Energy Science and Technology, George Washington University, VA 20147 ; Zhang Zhonghai, E-mail: zhonghaizhangwill@gmail.com ; ... - Journal of Solid State Chemistry

The photoelectrochemical water splitting and simultaneous photoelectrocatalytic degradation of organic pollutant were achieved on TiO{sub 2} nanotube electrodes with double purposes of environmental protection and renewable energy production under illumination of simulated solar light. The TiO{sub 2} nanotube arrays (TiO{sub 2} NTs) were fabricated by a two-step anodization method. The TiO{sub 2} NTs prepared in two-step anodization process (2-step TiO{sub 2} NTs) showed much better surface smoothness and tube orderliness than TiO{sub 2} NTs prepared in one-step anodization process (1-step TiO{sub 2} NTs). In the photoelectrochemical water splitting and simultaneous photoelectrocatalytic decomposition process, the 2-step TiO{sub 2} NTs electrode showedmore »« less
All-vanadium photoelectrochemical storage cells using dye sensitized geometry-enhanced TiO{sub 2} nanobelts

Journal Article Shen, Yi ; Wei, Zi ; Liu, Dong ; ... - Materials Research Bulletin

Highlights: • Dye-sensitized photoelectrode using nanostructured anatase TiO{sub 2} nanobelts was studied in photoelectrochemical storage cells. • An intricate balance between a series of charge-transfer processes related to the dye sensitizer, redox species, and photoelectrode was discovered. • Under AM1.5 illumination rapid charge transfer in the 1D nanobelts enhances photocurrent. • Large specific surface area of the photoelectrode dominates the performance under visible light. - Abstract: Photoelectrochemical (PEC) devices, which use solar energy to drive charge transfer, have been considered as a low cost and effective approach to harvest energy from the sun. Dye sensitization designs are promising alternative tomore »« less
