Summary: The efficiency of CIGS solar cells has been improving due to the application of Alkali-PDT technology in recent years. However, there are still some controversies regarding the influence of postdeposition treatment on the electronic structure of the absorber surface. The valence band of the absorber surface moves downward after postdeposition treatment, but there are two different situations for the position of the conduction band.

Summary: In this study, the impact of replacing the conventional CdS layer with In2S3 layer in CIGS-based solar cells was investigated. The efficiency of the solar cells was found to be influenced by the concentrations of Ga in the CIGS absorber, the band gap of the In2S3 buffer layer, and the band gap of the NayCu1-yIn5S8 interfacial layer. The results showed that the substitution of CdS with In2S3 improved the efficiency of the solar cells under certain conditions.

Summary: Chemical bath methods for growing thin film semiconductors produce a lot of waste solvent and chemicals. This study successfully replaced the toxic chemical bath deposited CdS buffer layer with a benign inkjet-printed and annealed Zn(O,S) layer, greatly reducing solvent and chemical usage. The wetting and final performance of the Zn(O,S) layer on CIGS can be controlled by various factors, with the best device efficiency reaching 13.5% through optimization.

Summary: Pure sulfide kesterite is a promising photovoltaic technology due to its excellent properties, but current efficiencies are limited due to several issues, including defects and nonoptimal band alignment. Experimental procedures combining TiO2 with kesterite have shown modest performance, but in this study, we report promising results using ALD-TiO2 as a buffer layer, achieving efficiencies comparable to reference devices.

Summary: The formation of a MoSe2 intermediate layer at the Mo/Cu(In,Ga)Se-2 (CIGS) interface can effectively reduce the back-contact barrier and improve hole transport in CIGS solar cells. This study demonstrates a method of depositing a room-temperature amorphous CIGS intermediate layer on the Mo substrate, which reacts with the Mo substrate to form a thin MoSe2 layer at high temperatures. This approach enables high-efficiency CIGS solar cells without the need for a selenium atmosphere during the sputtering process.

Summary: Blending metakaolin with slag in alkali-activated materials can achieve both acceptable engineering properties and durability. NMR spectroscopy is used to investigate the structure of alkali-activation products, but there is no consensus on the analysis of NMR spectra for identifying the phases formed in binary slag-metakaolin mixtures. This study characterizes the phase composition and reaction degree of alkali-activated metakaolin-slag blends, and shows that the incorporation of slag results in higher reactivity and compressive strength of metakaolin.

Summary: This study used X-ray absorption spectroscopy to determine the local atomic environment of iodine in different forms in aluminoborosilicate glasses. The results revealed that iodide ions (I-) were surrounded by Na+ or Ca2+, while iodate ions (I5+) were surrounded by three oxygen atoms. The I-O distance in iodate ions in glasses was comparable to the distance in crystalline compounds.

Summary: This study found that increasing the H2O/Na2O ratio in metakaolin-based geopolymers resulted in decreased compressive strength. However, it did not affect the geopolymer structure but impacted the reactivity of the precursor and porosity evolution. The reaction degree, as deduced from NMR spectral analysis, correlated with the cumulated released heat determined by isothermal calorimetry. The maximum loss tangent from dynamic rheology was linearly related to strength development.

Summary: This study investigates the adsorption of phosphated species on the TiO2 anatase surface using a multi-scale and multi-technique approach. The structure of complexes formed upon adsorption of phosphates on anatase under different pH conditions is identified for the first time by progressively ethyl-substituting the phosphates. The adsorbed amount of these molecules on TiO2 is quantified by recording adsorption isotherms as a function of pH. Zeta potential measurements and spectroscopic analysis are used to study the changes in surface charge and the structure of surface complexes, respectively. The results show that the amount of adsorbed species increases with decreasing pH, reaching a maximum at pH 2. Orthophosphate and monoethyl-phosphate exhibit similar adsorption amounts, while di- and tri-ethyl substitutions lead to a sharp decrease in adsorption.

Summary: This study proposes a simple and versatile method for preparing Zn(II)-poly(carboxylates) reticulated binders, which significantly improve the electrochemical performance of silicon-based negative electrodes. The formation of carboxylate-Zn(II) coordination bonds is investigated, and mechanical characterizations reveal better cohesion, adhesion, hardness, and elastic modulus of the coordinated binder. Operando dilatometry experiments show reduced electrode expansion and improved capacity retention of over 30% after 60 cycles for the coordinatively reticulated electrodes.

Summary: The functionalization of MXenes, a class of 2D materials, can significantly modify their physicochemical properties. Through experiments and theoretical calculations, we found that the carbon NMR signal in MXenes is highly sensitive to functionalization, even though carbon atoms are not directly bonded to the surface groups. We developed a theoretical model to quantitatively relate the 13C NMR shift to different surface compositions and the number of surface chemistry variants induced by different etching agents.

Summary: Silicon is a promising alternative to graphite for lithium-ion battery negative electrodes due to its high capacities. Coating silicon particles with metal-organic frameworks (MOFs) has shown improved electrochemical performance. However, a 20 nm thick layer of MOF on the surface of silicon particles did not result in significant modifications of the electrochemical performance in practical electrode loading conditions.

Summary: This study proposes a simple and versatile method for preparing Zn(II)-poly(carboxylates) reticulated binders by adding Zn(II) precursors into a preoptimized poly(carboxylic acids) binder solution. These binders significantly improve the electrochemical performance of silicon-based negative electrodes. The formation of carboxylate-Zn(II) coordination bonds is investigated using rheology and spectroscopic techniques. Mechanical characterizations show that the coordinated binder offers better electrode coating cohesion and adhesion, as well as higher hardness and elastic modulus, even in the presence of a carbonate solvent. Operando dilatometry experiments demonstrate that the electrode expansion during lithiation is reduced, mitigating electrode mechanical failure. These coordinatively reticulated electrodes outperform their uncoordinated counterparts with an improved capacity retention of over 30% after 60 cycles.

Summary: Recently, metal-organic frameworks (MOFs) that combine organic and inorganic redox-active moieties have attracted attention in electrochemical energy storage. In this study, we focused on MIL-53(M) (M = Al, Fe) analogues based on 2,5-dioxo-1,4-benzenedicarboxylate, as this ligand has shown interesting electrochemical activity in the solid state. We attempted to chemically lithiate the title solids through various synthetic paths and characterized the resulting solids using several techniques. We found that the lithiation process differed significantly for M = Al and Fe, and evaluated the electrochemical extraction/uptake of Li+ in the lithiated derivatives. Although their storage capacities were moderate, the presence of a minor amount of M3+ cations improved the long term capacity retention.
