Perovskites
In article number 2307960, Xiao Wang, Longbin Qiu, and co‐workers developed an ultrahigh humidity treatment strategy to facilitate the effective diffusion of formamidinium iodide from the top surface to the buried bottom interface on the sequential vapor‐deposited bilayer structure. High‐efficiency and stable perovskite solar cells deposited by a sequential vapor deposition process with...
The quality of two‐step processed perovskites is significantly influenced by the distribution of organic amine salts. Especially, modulating the distribution of organic amine salts remains a grand challenge for sequential vapor‐deposited perovskites due to the blocking effect of bottom compact PbI2. Herein, an ultrahigh humidity treatment strategy is developed to facilitate the diffusion of formamidinium...
The Li‐CO2 battery has great potential for both CO2 utilization and energy storage, but its practical application is limited by low energy efficiency and short cycle life. Efficient cathode catalysts are needed to address this issue. Herein, this work reports on molecularly dispersed electrocatalysts (MDEs) of nickel phthalocyanine (NiPc) anchored on carbon nanotubes (CNTs) as the cathode catalyst...
Efficient Perovskite Solar Modules
In article number 2301110, Sisi He, Longbin Qiu, and co‐workers design a controllable release and deposition of Ni2+ by adding amino‐alcohol ligands, which enhance the anti‐sedimentation of the precursor solution during chemical bath deposition and the uniformity of the deposited hole transport layer with large area. The authors fabricate highly reproducible and...
A scalable and low‐cost deposition of high‐quality charge transport layers and photoactive perovskite layers are the grand challenges for large‐area and efficient perovskite solar modules and tandem cells. An inverted structure with an inorganic hole transport layer is expected for long‐term stability. Among various hole transport materials, nickel oxide has been investigated for highly efficient...
Nanozyme‐based chemodynamic therapy (CDT) for fighting bacterial infections faces several major obstacles including low hydrogen peroxide (H2O2) level, over‐expressed glutathione (GSH) in infected sites, and inevitable damage to healthy tissue with abundant nonlocalized nanozymes. Herein, a smart ultrasmall Fe3O4‐decorated polydopamine (PDA/Fe3O4) hybrid nanozyme is demonstrated that continuously...
Volumetric performance is of great importance in today's energy storage devices, and is used to evaluate their competitiveness in the markets of miniaturized electronic devices and space‐constrained electric vehicles. Supercapacitors suffer from a low volumetric energy density in spite of their high power and long cycle life because of their use of porous but low‐density carbons. This review considers...
Molybdenum phosphide (MoP) is regarded as one of the most promising alternatives to noble‐metal based electrocatalysts for efficient hydrogen evolution reaction (HER) due to its similar d‐band electronic structure to noble metals and tunable features associated with phase and composition. However, it still remains a great challenge to construct MoP electrocatalysts with abundant active sites that...
Heterostructured Electrocatalysts
In article number 2102413, Baocang Liu, Rui Gao, Jun Zhang, Bin Liu, and co‐workers report the construction of a novel heterostructured electrocatalyst of CePO4/MoP/carbon cloth (CC) constituting MoP nanobelts with surface‐decorated CePO4 nanoparticles on CC for hydrogen evolution reaction (HER). The CePO4/MoP/CC electrocatalyst exhibits a low overpotential of 48...
