Summary: The charge carriers in single-junction solar cells can be easily extracted and collected, resulting in low charge carrier accumulation and energy loss. However, obtaining a balance between the densities of the extracted holes and electrons in tandem solar cells is challenging. This research proposes a charge-carrier-dynamic management strategy for inorganic perovskite/organic tandem solar cells, which improves the hole density and hole transport ability, leading to a balanced charge carrier recombination and reduced energy loss.

Summary: This study develops a dual-interface engineering approach to improve the performance of all-inorganic wide-bandgap CsPbI2Br-based front sub-cells in perovskite/organic tandem solar cells (POTSCs). By mitigating the defects and carrier recombination induced by interface defects and perovskite grain boundaries, the CsPbI2Br-based front sub-cells achieve a high power conversion efficiency (PCE) of 17.0% and open-circuit voltage (V-OC) of 1.347 V. Furthermore, by integrating these dual-interface engineered front sub-cells with narrow-bandgap PM6:CH1007-based rear sub-cells, a record PCE of 23.21% is obtained for the POTSCs.

Summary: Perovskite solar cells (PSCs) with over 25% power conversion efficiency have been achieved through efficient surface passivation. However, current post-treatment strategies can only repair the defects at the top interface. In this study, an ion-diffusion management strategy is proposed to simultaneously modulate the top interfaces, buried interfaces, and bulk interfaces of the perovskite film, achieving passivation of all interface defects. By using double interactive salts of octylammonium iodide (OAI) and guanidinium chloride (GACl) on the 3D perovskite surface, the diffusion of ions can be controlled, resulting in a dimensionally broadened 2D capping layer. This approach leads to the formation of n-inter-i-inter-p five-layer structured PSCs with a champion PCE of 25.43% (certified 24.4%), and improved operational stability of perovskite solar cells.

Summary: In this study, simple Ag@Pt bimetallic nanocubes were used to explore the mechanism of hot electrons from excitation and transmission within a plasmonic metal heterostructure and their contribution to the electrochemical hydrogen evolution reaction (HER). Experimental and theoretical results confirmed that the introduction of thin Pt shells resulted in hot electrons becoming the dominant plasmon decay pathway, and HER could be significantly enhanced through a cascaded manner. This work provides an important reference for the design and application of plasmonic metal heterostructure catalysts.

Summary: By designing and preparing SnS2/SnS hetero-junction nanosheets with full-band response, efficient photoreduction of Cr(VI) was achieved. The SnS2/SnS heterojunction with tight interfacial links facilitated inter-electron hole transport, leading to high photocatalytic efficiency. Moreover, the presence of SnS improved optical absorption capacity and enhanced photo-thermal conversion efficiency, accelerating the separation ability of photogenerated carriers. Our work provides a promising concept for continuous Cr(VI) removal under all-weather conditions, including weak light irradiation.
