Summary: Gellan gum/poly(3-hexylthiophene)/lithium chloride gels with different ratios of LiCl were synthesized and used as gel electrolytes in dye sensitized solar cells (DSSCs). The presence of 6 M LiCl prevented shrinkage of gels and increased surface energy values, resulting in good adhesive property. The flexible nature of LiCl-contained gels at low temperatures makes them suitable for various conditions and cell architecture. By using these gel electrolytes, higher open circuit potentials and improved solar conversion efficiency were achieved, making them a promising alternative to address the leakage and evaporation issues of liquid electrolytes in DSSCs.

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: 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 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.

By adding ligand-capped CsPbI3 quantum dot solution as an antisolvent, lattice-matching CsPbI3 QDs act as heterogeneous nucleation centers and ligands regulate the crystallization kinetics, reducing residual strain. This strategy improves the film's performance by increasing grain size, decreasing defects, reducing nonradiative recombination, and improving charge transfer efficiency.

Summary: In this study, CsPbI2Br quantum dots were synthesized by the hot injection method, and the effect of the purification process on their amplified spontaneous emission (ASE) properties was investigated. The results showed that the volume ratio of n-hexane vs EtOAc had a significant impact on the optical performance. When the volume ratio was 1:5, the quantum dots had a larger size, which increased light scattering and absorption cross-section, achieving the lowest ASE threshold of 0.301 mJ/cm2. This work not only provides a facile strategy to obtain low-threshold CsPbI2Br quantum dots but also enriches the application prospects of perovskite lasers.

Summary: To solve the toxicity issues related to lead-based halide perovskite solar cells, a lead-free double halide perovskite Cs2AgBiBr6 is proposed. However, the reduced rate of charge transfer affects the optoelectronic performance of double perovskites. By using interface engineering, a series of pyridine-based small molecules with different arms attached to the pyridine core are designed as hole-selective materials. The solar cells fabricated using Cs2AgBiBr6 as a light harvester and the designed hole-selective layer showed an unprecedented 2.9% power conversion efficiency. Our findings provide guidance for designing small molecules for electro-optical applications and developing lead-free perovskite materials for solar applications.

Summary: We report an easy and universal anion modification strategy by incorporating a series of guanidinium salts with different anions (guanidinium bromide, guanidinium thiocyanate, and guanidinium acetate) to inhibit the absorption of methanol on the surface of perovskite quantum dots (QDs) and improve the photovoltaic performance of perovskite QD solar cells. All anions have a positive effect on inhibiting methanol absorption, enhancing charge transfer, and passivating defects. The devices based on guanidinium acetate achieve a power conversion efficiency (PCE) of 7.04%, which is the highest among inorganic CsPbBr3 QD solar cells. Moreover, these CsPbBr3 QD solar cells exhibit high transparency in the entire visible spectrum region, showing promising applications in solar windows.
