Summary: The degradation behaviors of inverted PM6:IT-4F solar cells with different ZnO layers were systematically investigated, revealing that photochemical reactions at the IT-4F/ZnO interface play a key role in the decomposition of IT-4F. Hydroxyl radicals generated by the photo-oxidation of dangling hydroxide by ZnO are confirmed as the main reason causing the decomposition. Treatment of ZnO with hydroxide and/or hydroxyl radical scavenger is found to improve the stability of the PSCs, supporting the proposed degradation mechanism.

Summary: Organic-inorganic halide perovskites have a unique self-healing ability, where high-energy defects created by external stimuli can be healed by removing the perovskite from the degradation source. This property has been showcased in devices, extending their lifetime and mechanical durability. However, the mechanistic details and theory behind this trait are still limited. Understanding the intrinsic self-healing property can lead to the design of perovskite solar cells with extended lifetimes and durability.

Summary: Delayed fluorescent (DF) materials, with high internal quantum efficiency and improved luminescent lifetime, have drawn extensive attention due to their advantages of low toxicity, environmental friendliness, stable luminescence, easy preparation, and low cost, compared to traditional afterglow materials. Most DF materials based on carbon dots (CDs) are achieved by embedding CDs in a matrix with covalent bonds, hydrogen bonds, or other supramolecular interactions. Recently, matrix-free self-protective CDs-based DF materials have emerged. This review provides a systematic summary of the DF mechanism and structural regulation strategies of CDs-based DF materials, and introduces their applications in anti-counterfeiting, information encryption, temperature sensing, and other fields. Finally, the existing problems and future potentials of CDs-based DF materials are proposed and discussed.

Summary: Improving the thermal stability of polymer solar cells (PSC) is crucial for their industrialization. This paper systematically investigates the effect of high-temperature thermal annealing on the device performance of state-of-the-art polymer:non-fullerene (PM6:Y6) solar cells with an inverted structure. The results reveal that the overall performance decay is mainly attributed to the decrease in open-circuit voltage and fill factor, while the short circuit current remains relatively stable. Pre-annealing on specific films results in different performance decays, indicating that the degradation at the interface is the main reason for the overall performance decay. Further analysis confirms the increased interfacial charge recombination after thermal annealing.

Summary: Stable interface adhesion and bending durability are basic requirements for flexible organic solar cells (FOSCs) in wearable electronics. The weak interface adhesion between MoO3 hole transporting layer (HTL) and the organic photoactive layer was found to be the main reason for poor bending durability. By inserting an interface bonding layer with a thermoplastic elastomer, the interface adhesion force of MoO3 HTL and the active layer was effectively improved, ensuring more than 90% of the initial efficiency remaining after 10000 bending. Meanwhile, the FOSCs achieved high efficiencies of 14.18% and 16.15% for the PM6:Y6 and PM6:L8-BO devices, respectively.
