Summary: Conductive polymer blend gel electrolytes improve the stability of dyesensitized solar cells by reducing leakage and enhancing electrode adhesion. In this study, polyvinylpyrrolidone (PVP) and polyaniline (PANI) blends were synthesized through in-situ polymerization and characterized using various methods. The optimal composition of the electrolyte solution was selected, and the conductivity was found to be influenced by salt concentration. Solid-state dye-sensitized solar cells with gel electrolytes exhibited better long-term stability compared to conventional cells.

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 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.
