Summary: Inverted perovskite solar cells (PSCs) have gained attention due to their low-temperature fabrication process. However, the limited availability of electron transport materials, particularly the commonly used PCBM, compromises the efficiency and stability of the cells. In this study, a new electron transport material called EPF03 was synthesized and tested in inverted PSCs, showing a significant improvement in efficiency compared to PCBM. The results also suggest that EPF03 can enhance the stability and photostability of perovskite solar cells.

Organic binary charge-transfer compounds of 2,2′: 6′,2′′: 6′′,6-trioxotriphenylamine and a pyrene-annulated azaacene as donors

Rajorshi Das, Michael Linseis, Stefan M. M. Schupp, Franciska S. S. Gogesch, Lukas Schmidt-Mende, Rainer F. F. Winter

Summary: Three binary charge-transfer (CT) compounds formed by the donor 2,2':6',2'':6'',6-trioxotriphenylamine (TOTA) and the acceptors F(4)TCNQ and F(4)BQ, as well as a CT compound formed by a pyrene-annulated azaacene (PAA) and the acceptor F(4)TCNQ, were reported. The identities of these compounds were confirmed by various spectroscopic techniques and single-crystal X-ray diffraction. The crystal structures revealed different stoichiometries for each compound, and the spectroscopic data indicated varying degrees of charge transfer. The compounds exhibited intricate packing motifs in the crystal lattice and showed CT transitions in the solid-state UV-vis-NIR spectra. The electrical conductivity of the compounds varied, with the CT compounds containing F(4)TCNQ being insulators and (TOTA)(2)·F(4)BQ showing weak conductivity.

Stabilizing lattice oxygen and interface chemistry of Ni-rich and Co-poor cathodes for high-energy lithium-ion batteries

Wu Wei, Zhihong Wang, Liyun Yao, Hao Jiang, Chunzhong Li

Summary: In this study, CeO2-x-coated LiNi0.9Co0.045Mn0.045Al0.01O2 was used to stabilize the lattice oxygen of Ni-rich and Co-poor cathodes, resulting in a reversible oxygen-storage protective layer and improved crystal and interface structure. The obtained cathode exhibited a high specific capacity of 223 mA h g(-1) at 0.1C and 140 mA h g(-1) even at 10C, with 96.7% capacity retention at 1C after 100 cycles in a coin-type half-cell. About 90.1% capacity retention could still be obtained at 1C after 300 cycles in a pouch-type full-cell. This work provides a viable method for stabilizing the lattice oxygen of Ni-rich and Co-poor cathodes.

Boosting Hydrogen Peroxide Electrosynthesis via Modulating the Interfacial Hydrogen-Bond Environment

Yushuang Fang, Yu Fan, Kunchi Xie, Wangxin Ge, Yihua Zhu, Zhiwen Qi, Zhen Song, Hongliang Jiang, Chunzhong Li

Summary: Designing an efficient electrode-electrolyte interface for H2O2 electrosynthesis is challenging. However, adding dimethyl sulfoxide (DMSO) to the electrolyte can improve the selectivity and activity of H2O2 production. The formation of hydrogen bonds between DMSO and water at the electrode-electrolyte interface reduces water dissociation, leading to improved selectivity of H2O2 synthesis. This work highlights the importance of regulating the interfacial hydrogen-bond environment for enhancing electrochemical performance.

Uncovering solvent-engineering mechanisms in Y6:PM6 solar cells

Timo Raab, Tobias Seewald, Stefan Kraner, Lukas Schmidt-Mende

Summary: This study investigates the influence of 1-chloronaphtalene (CN) on the spin coating of Y6:PM6 solar cells dissolved in chloroform. The film formation of Y6:PM6 can be divided into two parts in the presence of CN, with one part related to the evaporation of chloroform and the other part related to the evaporation of CN. Even at low CN concentration, the film formation is not completed for several minutes after the spin coating process. The removal of CN can be achieved by spin coating the electron transport layer PDINN from methanol, resulting in comparable performance to solar cells with more common CN concentrations.

Ethylenediamine Vapors-Assisted Surface Passivation of Perovskite Films for Efficient Inverted Solar Cells

Muhammad Irfan Haider, Hao Hu, Tobias Seewald, Safeer Ahmed, Muhammad Sultan, Lukas Schmidt-Mende, Azhar Fakharuddin

Summary: Defects in halide perovskites limit charge transfer, induce nonradiative recombination, and accelerate degradation in perovskite solar cells (PSCs). Passivating these defects using ethylenediamine (EDA) through vapor annealing enhances photovoltaic performance, increasing open-circuit voltage by over 100 mV and improving power conversion efficiency by approximately 22%. This improvement is attributed to upward shift in Fermi energy level, reduced lattice strain and Urbach energy, and reduced nonradiative recombination upon EDA passivation. The EDA-modified PSCs also demonstrate improved shelf-life, retaining 87% of initial efficiency after 850 hours.

Zhihong Wang, Wu Wei, Qiang Han, Huawei Zhu, Ling Chen, Yanjie Hu, Hao Jiang, Chunzhong Li

Summary: A microstructure engineering strategy is used to synthesize elongated primary particles radially aligned Ni-rich cathodes through regulation of precipitation rates and flow field distributions. The resulting cathode exhibits enlarged lattice distance and highly exposed (003) plane, showing significant advantages such as high-rate, long-cycle life, and thermal stability. After modification, an exceptionally long life is achieved with a capacity retention of 90.1% at 1C and 84.3% at 5C after 1500 cycles within 3.0-4.3 V in a 1.5-Ah pouch cell. This work offers a universal strategy to enhance the durability of Ni-rich cathodes by achieving isotropic strain distribution.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
