Journal Article Prasad, Umesh ; Young, James L. ; Johnson, Justin C. ; ... - Journal of Materials Chemistry. A

Photoanodes containing a WO ₃ /BiVO ₄ heterojunction have demonstrated promising photoelectrochemical water splitting performance, but the ability to effectively passivate the WO ₃ /BiVO ₄ interface has limited charge transport and collection.

100-Fold Enhancement of Charge Transport in Uniaxially Oriented Mesoporous Anatase TiO₂ Films

Journal Article Li, Ke ; Liu, Jie ; Sheng, Xia ; ... - Chemistry - A European Journal

Mesoporous semiconductor films are of considerable interest for applications in photoelectrochemical devices, however, despite intensive research till now, their charge transport properties remain significantly lower than their single-crystal counterparts. Herein, we report a novel low-temperature template-free technique for growing high surface area mesoporous anatase TiO2 films with a preferred [001] crystalline-orientation on FTO-coated glass substrate. Compared to mesoporous films that comprised of randomly oriented crystallites, the uniaxial orientation enables a 100-fold increase in the rate of electron transport. The uniaxially oriented mesoporous anatase TiO2 films exhibit should greatly facilitate the development and application of photoelectrochemical and electrochemical devices.

Enhanced separation efficiency of photoinduced charges for antimony-doped tin oxide (Sb-SnO{sub 2})/TiO{sub 2} heterojunction semiconductors with varied Sb doping concentration

Journal Article Zhang, Zhen-Long ; Ma, Wen-Hai ; Mao, Yan-Li ; ... - Journal of Applied Physics

In this paper, antimony-doped tin oxide (Sb-SnO{sub 2}) nanoparticles were synthesized with varied Sb doping concentration, and the Sb-SnO{sub 2}/TiO{sub 2} heterojunction semiconductors were prepared with Sb-SnO{sub 2} and TiO{sub 2}. The separation efficiency of photoinduced charges was characterized with surface photovoltage (SPV) technique. Compared with Sb-SnO{sub 2} and TiO{sub 2}, Sb-SnO{sub 2}/TiO{sub 2} presents an enhanced separation efficiency of photoinduced charges, and the SPV enhancements were estimated to be 1.40, 1.43, and 1.99 for Sb-SnO{sub 2}/TiO{sub 2} composed of Sb-SnO{sub 2} with the Sb doping concentration of 5%, 10%, and 15%, respectively.

Low temperature perovskite solar cells with an evaporated TiO₂ compact layer for perovskite silicon tandem solar cells

Journal Article Bett, Alexander J. ; Schulze, Patricia S. C. ; Winkler, Kristina ; ... - Energy Procedia (Online)

Silicon-based tandem solar cells can overcome the efficiency limit of single junction silicon solar cells. Perovskite solar cells are particularly promising as a top cell in monolithic tandem devices due to their rapid development towards high efficiencies, a tunable band gap with a sharp optical absorption edge and a simple production process. In monolithic tandem devices, the perovskite solar cell is deposited directly on the silicon cell, requiring low-temperature processes (< 200 °C) to maintain functionality of under-lying layers of the silicon cell in case of highly efficient silicon hetero-junction (SHJ) bottom solar cell. In this work, we present amore »« less

The role of nanoscale seed layers on the enhanced performance of niobium doped TiO₂ thin films on glass

Journal Article Nikodemski, Stefan ; Dameron, Arrelaine A. ; Perkins, John D. ; ... - Scientific Reports

Transparent conducting oxide (TCO) coatings with decreased cost and greater process or performance versatility are needed for a variety of optoelectronic applications. Among potential new TCO candidates, doped titanium dioxide is receiving particular interest. In this study, niobium-doped titania bilayer structures consisting of a nanoscale seed layer (deposited by atomic layer deposition or RF magnetron sputtering) followed by a thick bulk-like layer were grown directly on glass in order to examine the effects of the seed layer processing on the subsequent crystallization and electrical properties of these heterostructures. Observations from Raman spectroscopy suggest that higher oxygen content in the seedmore »« less
