This work provides effective small molecule regulatory strategy by using 2,6-pyridinedicarboxamide (PC) to regulate the crystallization kinetics of CsPbI2.75Br0.25 inorganic perovskite, prolong the annealing time in air, passivate uncoordinated Pb2+. Eventually, a record PCE of 22.07% with high V OC 1.342 V is achieved based on n–i–p inorganic perovskite...

In this work, the aggregation-related photophysical properties of bulk and interfacial states are disentangled through the construction of bilayer organic solar cells. Machine learning is used to enable the assignment of specific structural motifs to elementary device photophysics. The results highlight those different aspects of structural features...

Through a dual cascade synthesis strategy mediated by the paired-electrolysis based on a novel microenvironment-inbuilt metalized covalent organic framework (MCOF) heterojunction, the simultaneous production of high value-added dimethyl carbonate and iodoform has been achieved in an energy-saving and economical manner, showcasing a new paradigm for...

The development of perovskite solar modules is of essence to commercialization of perovskite photovoltaics regarded as one of the next-generation sustainable energy conversion technologies. Electron-transport layer acts as the key factor determining performance and reliability. This work demonstrates surface engineering by pH modulation in SnO2 colloidal...

In this work, heptafluorobutyramide (HFT) and LiNO3 additives are introduced in Li metal batteries with carbonate-based electrolyte. The HFT can promote dissolution of LiNO3 and inhibit generation of destructive HF. The additives will be preferentially reduced to LiF and Li3N on Li metal, prompting the full cell matched with LiFePO4 to maintain high...

A new perspective of previously ignored anion tuning is proposed to improve the hydrogen storage performance of 2LiBH4−MgH2 (Li-RHC). The anion, S2- bridges the reversible conversion between Li2S and MgS, eventually promoting the cycling stability of Li-RHC to an unprecedented number of laps. The results highlight the important role of anion in enhancing...
