Summary: Dye-sensitized solar cells (DSSCs) are a promising solution for portable electronics and IoT applications due to their low-cost fabrication and high efficiency. However, the main obstacle to their large-scale exploitation is their limited long-term stability caused by liquid electrolytes. This review summarizes advances in alternative polymer electrolytes, with a focus on polysiloxane-based poly(ionic liquid)s, and evaluates their behavior in DSSCs. The assessment of printability for liquid and gel polymer electrolytes, particularly polysiloxane-based electrolytes, is also discussed.

Summary: In this study, the photovoltaic capabilities of a metal-free organic dye (CDIB) as a sensitizer and co-sensitizer for dye-sensitized solar cells (DSSCs) were investigated. The efficiency of the DSSC with CDIB sensitizer and IL-15% electrolyte reached 1.86%. Furthermore, the power conversion efficiency of DSSC with co-sensitized dye was increased by 23.29%, mainly due to an increase in short-circuit current density and open-circuit voltage.

Summary: This study synthesized gold (Au) and poly(3-hexylthiophene) (P3HT) composite nanoparticles (Au@P3HT) for modifying dye-sensitized solar cells (DSSCs). The experimental results showed that the spherical Au@P3HT nanoparticles had a mean diameter of 6 nm. The modification with Au@P3HT not only enhanced light absorption in the long wavelength region, but also improved the incident photon to current conversion efficiency and increased the recombination resistance. The DSSC achieved an energy conversion efficiency of 9.34% using this method.

Summary: Electrochemical impedance spectroscopy (EIS) was used to study the ageing mechanism of dye-sensitized solar cells (DSSCs). The findings showed that the lack of sufficient redox complexes was the main cause of decreased performance after ageing. Additionally, high-resolution fluorescence detected X-ray absorption spectroscopy (HERFD-XAS) revealed the reduction of Co(iii) to Co(ii) during ageing.

Summary: Dye-sensitized solar cells (DSCs) suffer from reduced power conversion efficiency due to electron recombination with triiodide (I-3(-)) ions at the photoanode/electrolyte interface. Organic additives and inorganic oxide nanoparticles have been explored to reduce recombination and improve efficiency. In this study, aluminum-doped zinc oxide nanoparticles (AZO NPs) were investigated as an inorganic additive with ionic adsorption properties. The addition of AZO NPs significantly decreased recombination, increased open circuit voltage (V-OC) and fill factor (FF) values, and reduced hysteresis. The presence of AZO NPs also resulted in a negative shift in the Fermi level, indicating improved electron lifetime at the TiO2/electrolyte interface. Our findings suggest that AZO NPs have potential as an effective inorganic additive for improving DSC performance.

The synergistic effects of micro-nano-adsorbent-reinforced poly(lactic acid) (PLA) composites were investigated through rheological analysis. Various tests were conducted to examine the properties of the prepared composites, including tensile and hardness tests, crystallinity tests, elemental composition, and plasticity behavior tests. In-depth investigations and comparisons were carried out to confirm the efficacy of the created composites compared to other outcomes.

Summary: Polymeric rubber and organic semiconductor H2Pc-CNT composite-based shockproof deformable infrared radiation (IR) sensors were fabricated using a rubbing-in technique. The sensors showed decreased resistance and impedance when exposed to IR irradiation, and the temperature coefficients of resistance (TCR) were 1.2 and 1.1 for the surface-type and sandwich-type sensors, respectively. The high TCR value and novel composition of the H2Pc-CNT composite make these devices attractive for bolometric applications, and their easy fabrication and low-cost materials make them commercially viable.

Summary: Hysteresis effects in ionic-electronic devices can be used to develop switching memory devices for information storage and brain-like computation. Halide perovskite devices exhibit frequent hysteresis in current-voltage curves, which can be utilized to build effective memristors. These phenomena can be described by nonlinear differential equations involving current, voltage, and internal state variables similar to the Hodgkin-Huxley model for action potentials in neurons. Furthermore, introducing a capacitive coupling in the slow relaxation variable extends the neuron-style models to explain observations in impedance spectroscopy of MAPbBr solar cells and memristors.
