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 presents the design and fabrication of a photoanode composed of Au/SnS/TiO2 sensitized with natural dye for dye-sensitized solar cells (DSSCs). By calcination, a layer of spherical nano-TiO2 is prepared, and a layer of nano-SnS is deposited on the TiO2 photoanode using the continuous ion layer adsorption reaction (SILAR). The sensitized Au nanoparticles exhibit enhanced localized surface plasmon resonance (LSPR) effects and electron trapping ability, resulting in improved electron mobility and reduced electron recombination in the DSSC.

Summary: This study focuses on using upconversion phosphors (UCPs) to convert IR into visible light to enhance the efficiency of dye-sensitized solar cells (DSSCs). The addition of an optimal amount of UCPs significantly improves the power conversion efficiency (PCE) of DSSCs, while excess UCPs deteriorate efficiency due to rapid recombination and increased interfaces.

Summary: Fiber solar cells, woven into textiles, have shown potential in supplying electricity for wearables. However, achieving high power conversion efficiencies in real-world applications remains a challenge. A unique hybrid counter electrode was designed using metal current collector fiber, aligned carbon nanotube sheet, and porous titanium dioxide/poly(vinylidene fluoride-co-hexafluoropropylene) film. This design achieved a record power conversion efficiency of 12.52% and maintained efficiency below 10% after bending, twisting, or pressing for 1000 cycles. The integration of these fiber dye-sensitized solar cells with fiber batteries demonstrated an effective power solution for wearables.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
