Summary: By designing a hierarchical Li3VO4/NC sponge structure, ultrasmall LVO nanoparticles were adhered to N-doped carbon sponge, resulting in a shortened charge transport path, increased effective contact between electrolyte and host material, and improved reaction kinetics. The HLVO/NC SS anode exhibited outstanding lithium storage performance, with high reversible specific capacity (710 mAh g-1 at 0.2 A g-1), excellent high-rate property (303 mAh g-1 at 8 A g-1 after 7 periodic rate performance), and superior cycling stability (266 mAh g-1 at the discharge current of 8 A g-1 after 4000 cycles). The improved electrochemical performance of H-LVO/NC SS suggests that this structure design strategy could be applied to new-generation electrode structures and provide insights for the design of other batteries.

Summary: Optimizing the molecular packing and orientation of dopant-free hole-transport materials (HTMs) is an effective strategy for achieving high-performance perovskite solar cells (PSCs). By regulating the donor building blocks and using a large core unit, we successfully demonstrated tunable molecular packing and orientation of polymers. The developed PC-DPP conjugated polymer with a preferred face-on orientation showed enlarged hole mobility and improved efficiency in PSCs compared to the control PBDT-DPP polymer with a preferred edge-on orientation. This work opens up possibilities for developing dopant-free HTMs.

Summary: There is a significant efficiency gap between organic solar cells (OSCs) and inorganic solar cells. This is primarily due to the larger nonradiative energy losses in OSCs, which can be attributed to the characteristics of organic light-harvesting molecules. Rational design of light-harvesting molecules at the molecular and aggregation levels is crucial for improving the efficiency of OSCs.

Summary: Three non-fullerene acceptors BTP-OC4, BTP-OC6, and BTP-OC8 with different 4-alkyloxyphenyl side-chains were synthesized via a new route without organotin reagent. The length of the alkyloxy group did not affect the energy levels and absorption of the acceptors, but it modulated the crystallinity and morphology of the active layer. The PM6:BTP-OC6 system showed the lowest energy loss of 0.513 eV, the highest power conversion efficiency of 17.59%, and excellent stability. Furthermore, when Y6 was introduced, the PCE increased to over 18%. Our study demonstrates a feasible strategy to develop high-performance acceptors by fine-tuning the aromatic side chain.
