Summary: After the rapid development of single-junction perovskite solar cells and organic solar cells, improving their power conversion efficiencies has become increasingly difficult. Tandem solar cells are gaining more attention due to their higher theoretical efficiency compared to single-junction solar cells. While good device performance has been achieved for perovskite/silicon and perovskite/perovskite tandem solar cells, very few studies have been done on 4-terminal inorganic perovskite/organic tandem solar cells. This work successfully fabricates 4-terminal inorganic perovskite/organic tandem solar cells using semi-transparent inorganic perovskite solar cells and organic solar cells, achieving higher efficiency than reported 2-terminal and 4-terminal inorganic perovskite/organic tandem solar cells.

Summary: This work presents the use of Sn-Pb binary metal inorganic perovskites as narrow-bandgap absorbers for integrated 4-terminal all-inorganic perovskite tandem solar cells. Through tuning the Sn-Pb and I-Br contents, a series of Sn-Pb binary metal CsPb1-xSnxI3-yBry inorganic perovskites with tunable bandgaps ranging from 1.28 to 1.45 eV were synthesized. The resulting tandem solar cell achieved a remarkable power conversion efficiency over 18% and a high open-circuit voltage of 2.13 V, demonstrating the potential for solar fuel production.

Summary: In this work, dicyandiamide (DCD) is used as an antioxidative additive to address the pin-hole morphology and device instability issues in Sn-Pb mixed perovskite solar cells (PSCs). Through the addition of DCD, the crystallization and passivation of all-inorganic CsPb1-xSnxI2Br film is effectively regulated, resulting in improved efficiencies and stability in the inverted PSCs. Furthermore, by combining semitransparent PSCs and bottom PSCs, high efficiency 4-terminal tandem PSCs are demonstrated. This research paves the way for efficient all-inorganic perovskite tandem solar cells.

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).

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: In this study, different active sites of MoS2 were found to exhibit different catalytic selectivity for nitrogen reduction and hydrogen evolution reactions through DFT calculations. A new synergistic mechanism was proposed and a self-sacrificial strategy using g-C3N4 as templates was developed to synthesize 1T-MoS2 with an ultrahigh 1T content. This work provides a promising new direction for synchronizing selectivity and activity in multistep catalytic reactions.

Summary: This study investigates the effect of carbon-based conductive agents (CAs) on the performance of sulfide-based all-solid-state batteries (ASSBs). The results show that under low mass loading, CAs can deteriorate the performance of the cell due to side reactions with solid electrolytes. However, under high mass loading, CAs can promote charge transfer. The gradient design strategy is applied to minimize the adverse effects of CAs and optimize the electrode performance.

Summary: PbI2 films are crucial for the quality of PVK films in a two-step sequential deposition process. Microcrystal powder of PbI2 (P-PbI2) in micrometer size can produce higher-quality PbI2 films under low humidity conditions, while millimeter-sized PbI2 crystals (C-PbI2) allow the growth of denser films under heavy humidity conditions. PVK solar cells fabricated with P-PbI2 achieve the best power conversion efficiency (PCE) of 23.30% under low humidity of 30 +/- 5%, while C-PbI2 results in an impressive PCE of 21.09% under humidity conditions of 50 +/- 5%. This work offers insights for selecting lead iodide for PSC fabrication under air conditions.
