Summary: The study investigates the effect of 4-tertiary-butylpyridine (TBP) on improving the performance of dye-sensitized solar cells. The presence of TBP increases the transport number of iodide ions and the ionic conductivity of the electrolyte. The optimized DSC with TBP shows a conversion efficiency of 7.94%, a high V-OC of 0.709 V, and J(SC) of 17.22 mA cm(-2), a 35% increase in efficiency compared to when TBP is not present.

Summary: Thin films of solid-state polymer electrolytes (SSPEs) have been developed for dye-sensitized solar cells (DSCs) for the first time. Gel-electrolytes are prepared by utilizing a blend of poly(ethylene oxide) (PEO)/polyethylene glycol (PEG) and an acetonitrile-based iodide liquid electrolyte, and then cast onto a glass substrate to fabricate solvent-free SSPEs by evaporating the solvent. The SSPE films are sandwiched between photoelectrodes and counter electrodes to assemble the solid-state DSCs, and the PCE can be improved by introducing TiO2 nanofillers in the SSPEs. The high stability of the solid-state DSCs is demonstrated with a retention of 98% of their original efficiency after a 700-hour test period.

Summary: A complete printing process was developed for the fabrication of monolithic quasi-solid-state dye-sensitized solar cells (m-QS-DSSCs). The structures were constructed by printing TiO2 layers, a ZrO2 insulating layer, and a carbon counter electrode (CE) onto an FTO substrate, followed by printing a quasi-solid-state printable electrolyte (QS-PE) on top of the porous carbon CE. The optimized porous structures and characteristics of the ZrO2 and carbon layers enabled the m-QS-DSSCs to achieve an efficiency of 6.79% under 1 sun illumination.

Summary: Dye-sensitized solar cells (DSSCs) are cheaper and easier to produce than silicon-based solar cells. Carbon materials can be used as counter electrodes in DSSCs instead of platinum electrodes due to their catalytic characteristics and affordability. Copper (I) thiocyanate (CuSCN) has recently been considered a promising hole transport material for advanced solar cells. In this study, dye-sensitized solar cells were fabricated using carbon-graphite counter electrodes with solid-state CuSCN. The use of carbon-based composite with CuSCN counter electrode showed improved efficiency and stability, with a maximum conversion efficiency of 8.56% achieved under AM 1.5 solar conditions.

Summary: Self-assembled nanogratings formed by femtosecond laser writing in multicomponent alkali and alkaline earth containing alumino-borosilicate glasses were studied. The existence of nanogratings was investigated by varying laser parameters including pulse duration, energy, and polarization. Form birefringence, characteristic of nanogratings, was observed through retardance measurements. Glass composition was found to significantly impact the formation of nanogratings, with the Type II processing window decreasing as certain ratios increase. The ability to form nanogratings and its dependence on temperature were interpreted from a glass viscosity viewpoint.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
