Summary: Researchers have developed a simple and rapid voltage-assisted SILAR technique (VASILAR) to more efficiently load CdS/CdSe QDs into TiO2 mesoporous films. The electric field generated by imposing the voltage promotes the preferential deposition of CdS in the deep region of the films, achieving a uniform distribution. Sufficient space and channels are created for the loading of CdSe, and the growth and distribution of CdSe are well regulated with the help of electric field forces. The resulting CdS/CdSe co-sensitized QDSSCs exhibit an outstanding efficiency of 5.7% and remarkable stability.

Summary: Third-generation solar cells, such as dye-sensitized solar cells and quantum dot-sensitized solar cells, require counter electrodes (CEs) for their functionality. Platinum-based CEs are dominant but expensive, thus alternative materials like transition metal chalcogenides (TMCs) and transition metal dichalcogenides (TMDs) have been explored. This study provides a comprehensive review of the major components and working principles of these solar cells, and evaluates the performance efficiencies resulting from TMS-based CEs compared to Pt-based CEs.

Summary: Lead halide perovskite films with excellent optoelectronic properties are prepared using a residual strain regulation strategy. 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: 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.

In recent years, it has been transformed into a landmark complex integrating commerce, culture, and tourism, in line with regional development requirements. Detailed historical research and value evaluation are necessary to preserve the value of early modern reinforced concrete buildings as heritage sites and confirm their contemporary value as a space resource that meets political and economic requirements.
