Conductive nanofiber(NF)-network in nano scale is expected to act as a collector of excited carriers in a medium with short diffusion length of carriers.
For the effective usage of conductive NF-network in mesoporous media, we tried to actualize the composite structure of electrospun NF-network of Nb-doped TiO$_2$ (TNO) in a mesoporous TiO$_2$ layer keeping the network and its direct connection to conductive substrate.
The effects of inserted NF-network with different mesh size were examined for the performance of dye-sensitized solar cells (DSSCs).
By the insertion of NF-network, the power conversion efficiency $¥eta$ was increased by 29.3 ¥% resulting from the increase of the short circuit current density $J_{¥rm sc}$ by 31.3 ¥%.
From the time-resolved spectra of photovoltage and photocurrent, and electrochemical impedance spectra (EIS), it was found that photoelectrodes with NF-network had long lifetime of the electrons $¥tau_{¥rm e}$, small recombination rate of electrons $k_{¥rm eff}$, and large steady state electron density $n_{¥rm s}$.
The enhancement of photocurrent and the external quantum efficiency (EQE) also shows that TNO NF-network acts as a good carrier collector with the low leakage rate of photoexcited carriers.

Muhammad Zobayer Bin Mukhlish, Yuji Horie, Teruaki Nomiyama . Flexible Alumina-silica Nanofibrous Membrane and Its High Adaptability in Reactive Red-120 Dye Removal from Water .

Flexible and selfstanding membrane composed of ultrafine alumina-silica nanofibers (NFs) has been successfully fabricated by the electrospinning method, and further used as an adsorbent for the adsorptive decolorization of Reactive Red-120 (RR-120) dye from an aqueous system. Effects of pH, adsorbent dosage and contact time on adsorption have been studied. The adsorption of RR-120 on the NFs was found to be highly pH dependant and the optimum pH was found to be 3. The adsorption equilibrium data was explained well with the Langmuir isotherm model, and the maximum sorption capacity was found to be 884.95 mg/g, which was several folds higher than the adsorption capacity of a number of recently studied potential adsorbents. After adsorption, the NFs mat could be separated from the liquid phase conveniently and reused. The sorption kinetics was found to follow an intraparticle diffusion model. The high adsorption performance, excellent flexibility, easy recovery and reuse characteristic of the alumina-silica NFs membrane all favor its practical application in environmental remediation.

Mukhlish M. . Self-standing conductive ITO-silica nanofiber mats for use in flexible electronics and their application in dye-sensitized solar cells . Ceramics International43 ( 11 ) 8146 - 8152 2017.8Invited Reviewed

Language：English Publishing type：Research paper (scientific journal) Publisher：Ceramics International

For the realization of flexible electronics, we proposed a nonwoven mat of inorganic electrospun nanofibers (NFs) of amorphous silica that is flexible and heat-resistive as a candidate to replace a glass or plastic substrate. We attempted to add electrical conductivity using indium tin oxide (ITO) to create self-standing, nonwoven flexible mats completely composed of inorganic ceramic materials. Two methods were tested to make the ITO-silica NF mats: electrospun silica-NF mats drop coated by ITO and hybrid mats composed of ITO NFs and silica NFs fabricated by the dual-spinneret electrospinning technique. Our produced ITO-silica NF mats exhibited both mechanical flexibility and thermal stability, even after heat treatment at 450-650 ○C. The sheet resistance was 15-113 Ω/sq. We attempted to apply the obtained nonwoven conductive mats to the flexible photoanode of dye-sensitized solar cells (DSSCs) and highlighted the problems in the existing application.

Yuji Horie, Kazuhiro Daizaka, Hiroki Mukae, Shirong Guo, Teruaki Nomiyama . Enhancement of photocurrent by columnar Nb-doped TiO2 compact layer in dye sensitized solar cells with low temperature process of dc sputtering . Electrochimica Acta187 348 - 357 2016.1Enhancement of photocurrent by columnar Nb-doped TiO2 compact layer in dye sensitized solar cells with low temperature process of dc sputteringReviewed

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

The compact layer of niobium doped TiO2 (TNO) with columnar structure was prepared by a low temperature process of dc magnetron sputtering with high growth rate, and its effect on the carrier transport properties in dye sensitized solar cells (DSSCs) was examined by comparing with granular TNO compact layer prepared by a sol-gel method followed by a heat treatment at high temperatures. With a reactive dc magnetron sputtering using Nb-Ti alloy target and Ar-O mixed gas, columnar structure with preferred orientation along [220] was obtained when non-heated FTO/glass substrate was located closely to the high density plasma covering the target. The short circuit photocurrent density Jsc of columnar layer showed an increase even at thick region of > 200 nm in contrast to that of granular one. The en- hancement of Jsc was mainly explained by longer electron life time τe than granular one which may be originated from the dense structure of columnar layer covering FTO, as well as the small series resistance of columnar layer due to the reduction of inter grain resistance and the small electron mass along a-axis. However, the leak current from the surface of columnar grains was found to increase with the strong preferred orientation because of the dense surface trapping sites which might be caused by the low temperature crystal growth activated by adjacent plasma. For thinner region of 200 nm, the difference between columnar and granular layer was small, and the effect commonly obtained for compact layer was confirmed. Thus, even with the thickness of ∼ 100 nm being commonly used for compact layer, columnar layer made in this study has an advantage from the viewpoint of low temperature process and high growth rate.
