Summary: Latent heat thermal energy storage (LHTES) using phase change materials (PCMs) is effective in addressing energy supply-demand mismatch, but faces challenges of low thermal conductivity and leakage. Integrating porous supports and PCMs to fabricate shape-stabilized phase change materials (ss-PCMs) is one solution, with research on phase change heat transfer in porous ss-PCMs being crucial for system performance evaluation. Research gaps exist between phase change heat transfer and material preparation, and future studies should focus on numerical advancements and experimental investigations in this area.

Summary: This study investigates the photo-brightening effect of quasi-2D perovskites/PEO films under ambient storage, showing an increase of the photoluminescence quantum yield from 55% to 74% after 100 days. The presence of physically adsorbed water molecules and the passivation of surface Br vacancies contribute to the increasing radiative recombination rate, leading to this counterintuitive phenomenon. Stable light-emitting diodes (LEDs) using quasi-2D perovskites/PEO color filters are fabricated, achieving high stability of around 400 h@10 mA under operating ambient conditions, which is 20 times higher than 3D perovskite LEDs.
