Abstract Migration of ions can lead to photoinduced phase separation, degradation, and current–voltage hysteresis in perovskite solar cells (PSCs), has become a serious drawback for the organic–inorganic hybrid materials (OIPs). Here, inhibition ion migration is realized by supramolecular cation–π interaction between aromatic rubrene organic cations OIPs. The energy found be as strong 1.5 eV, which enough immobilize OIPs; this will thus obvious reduction defects films outstanding stability...
Abstract High nickel content layered cathodes, represented by NCM (LiNi x Co y Mn z O 2 , + = 1), are now widely employed in the market of electric vehicles, owing to their high energy density. With gradual increase and capacity, issues on cycling life safety become more serious. In this review, various strategies for improving performance summarized aspects surface coating, ionic doping, single‐crystal NCM. The coating strategy was separately described according physical property species,...
All-perovskite tandem solar cells (TSCs) hold great promise in terms of ultrahigh efficiency, low manufacturing cost, and flexibility, stepping forward to the next-generation photovoltaics. However, their further development is hampered by relatively performance low-bandgap (LBG) tin (Sn)-lead (Pb) perovskite (PSCs). Improving carrier management, including suppressing trap-assisted non-radiative recombination promoting transfer, significance enhance Sn-Pb PSCs. Herein, a management strategy...
Synergistic effects of lead chloride and phenethylammonium suppress the phase segregation non-radiative recombination in 1.73 eV wide- E g perovskite solar cells (PSCs), leading to a significantly reduced V OC -deficit 0.418 V.

Abstract Metal‐halide perovskite solar cells (PSCs) have emerged as a promising photovoltaic technology. Fabricating PSCs in ambient air can accelerate their low‐cost commercialization, since it remove the reliance on atmosphere‐controlled equipment. However, power conversion efficiency (PCE) of air‐fabricated still lags behind those fabricated glovebox. Here, based technology to fabricate high‐quality film air, compatible optimization is performed electron transport layer (ETL) further...

Bandgap-tunable mixed-halide perovskites offer exciting opportunities to construct efficient multijunction tandem solar cells. However, the ion migration always causes halide segregation, which inevitably creates detrimental defects and deteriorates photovoltaic performances. Here, we report a universal caging strategy suppress segregation by in situ formation of conjugated covalent organic frameworks (COFs) catalyzed PbX2 (X = Br I) during perovskite. Through theoretical calculation...
