Summary: In this study, a post-lithium (Li) treatment on TiO2 films was performed to enhance the optoelectronic features and power conversion efficiency (PCE) of dye-sensitized solar cells (DSSCs). The Li treatment reduced defects and improved the crystallinity of the TiO2 films. DSSCs fabricated using Li-treated TiO2 films as photoanodes showed a performance improvement of approximately 20% and a PCE of 10.5%, compared to the control DSSC with a PCE of 8.7%. The enhanced performance was attributed to improved structural properties, efficient charge transport, and suppression of recombination due to the passivation of trap states.

Summary: This work evaluates a novel metal-free donor-x-acceptor dye (AT-Pyri) for sensitizing TiO2 film photoanodes, demonstrating significant improvement in photocurrent and stability. The addition of triethanolamine (TEOA) to the electrolyte prevents degradation of AT-Pyri, and combining TEOA with methanol further enhances the photoelectrochemical water-splitting activity. The stabilization of the AT-Pyri photoanode is accompanied by a substantial increase in photocurrent and disappearance of transient spikes.

Summary: Dye-sensitized solar cells (DSSCs) have attracted attention for their low-cost processing, ability to work in diffuse light, and potential for building integrated photovoltaics (BIPV). However, their efficiency is low due to multiple issues. This study introduces a graphene/TiO2 scattering layer that enhances electron transport and light scattering. Results show that with 0.01 wt% graphene, a 33% higher photoconversion efficiency (PCE) was achieved compared to without scattering layer. However, PCE decreases at >0.01 wt% graphene due to loss of diffuse reflectance and higher optical absorption.

Summary: This study reports the impact of adding varying loadings of NZF nanoparticles into a TiO2 photoanode on the performance of DSSCs sensitized with natural and commercial dye molecules. The findings show that NZF greatly improves the photoconversion efficiency of the DSSCs, with the greatest improvement observed at an optimum loading of 50% w/w. The improved performance can be attributed to higher dye loading, improved electron transportation, and reduced electron recombination rates.

Summary: This study proposes a three-dimensional model of the interaction between charged or neutral domain walls and oxygen vacancies in hexagonal manganite YMnO3, and simulates it using Landau-Ginzburg-Devonshire theory, dynamic diffusion equation, and Maxwell's equation. The calculation shows that stiffness anisotropic factors can adjust the domain wall state and, ultimately, affect the distribution of oxygen vacancies. The electrostatic field generated by the bound charge is the key factor in changing the distribution of oxygen vacancies. Finally, the e-index law is used to fit the relationship between oxygen vacancy concentration and the polarization gradient along the z direction. Our theory provides a new way to modulate the distribution of oxygen vacancies through domain wall morphology in hexagonal YMnO3.

Summary: This study investigated the effective coercive field E-c(eff) of [001](c) poled 0.71Pb(Mg1/3Nb2/3)O-3-0.29PbTiO(3) (PMN-0.29PT) single crystals inside an ultrasonic curved array transducer as a function of frequency f from 10 kHz to 4 MHz. The results showed that Eeff c monotonically increased with f in the form of f(beta), reaching more than 6 kV/cm at 4 MHz, which is three times the conventional coercive field. The beta value changed at around 400 kHz due to a transition in domain switching. The study also revealed that the E-c(eff) of PMN-0.29PT single crystals under clamped boundary conditions was larger than that under free boundary conditions, indicating that strain confinement hinders domain switching in ferroelectric crystals. These quantitative results of E-c(eff) versus f provide valuable guidelines for designing high-frequency medical array transducers using PMN-PT single crystals.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
