Advanced Energy Materials, Год журнала: 2022, Номер 12(47)

Опубликована: Окт. 26, 2022

Abstract Li–O 2 batteries (LOBs) exhibit ultrahigh theoretical energy density, but sluggish reaction kinetics and adverse parasitic reactions seriously hinder their further development. It is thus urgent to exploit cost‐effective durable electrocatalysts perfect LOBs performance promote practical application. In this work, lattice‐matching composites are synthesized based on homologous heterostructure (HHS) with hollow nanocage‐like architecture. As expected, the unique architecture built‐in electric fields of NiS /NiSe HHS enables rapid transfer electron/ions, favorable electrolyte permeation cathode surfaces, provides sufficient active sites for oxygen evolution reduction reaction. Moreover, constructs can evidently catalyze formation dispersed platelet‐shape fluffy film‐like Li O discharge products via surface/solution routes due greatly reduced adsorption LiO intermediates fields, while NiSe counterparts induce films by surface path, limiting its electrocatalytic activities. These results suggest that engineering catalysts be an effective approach tuning formation, which holds attractive great application prospects in development high‐performance LOBs.

Bipolar Pseudohalide Ammonium Salts Bridged Perovskite Buried Interface toward Efficient Indoor Photovoltaics

Advanced Energy Materials, Год журнала: 2024, Номер unknown

Опубликована: Июнь 4, 2024

Abstract Due to the higher photon energy under indoor photovoltaic conditions, using perovskite materials with wider bandgaps has become a consensus. However, updating absorbers requires additional adaptations involving at least two layers of transport and interfaces, increasing development complexity. This study acknowledges that buried interface is primary location for generation photoinduced carriers, achieving efficient carrier separation this will solve most open circuit voltage ( V OC ) loss issues encountered in transitioning from solar photovoltaics photovoltaics. Therefore, class bipolar pseudohalide ammonium salts proposed use as bridging agents effectively resolve lattice misalignment insufficient driving force when broadening bandgap, thereby reducing The optimized device exhibits an excellent photoelectric conversion efficiency (PCE) 41.04%, record‐high 1.08 V. It also demonstrates impressive long‐term operational stability T 80 lifetime 1000 h. Substituting various non‐buried different categories wide‐bandgap does not alter effectiveness, proving its universality.

Abstract Hole transporting layers (HTLs), strategically positioned between electrode and light absorber, play a pivotal role in shaping charge extraction transport organic solar cells (OSCs). However, the commonly used poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) HTL, with its hygroscopic acidic nature, undermines operational durability of OSC devices. Herein, an environmentally friendly approach is developed utilizing nickel acetate tetrahydrate (NiAc·4H 2 O) [2‐(9H‐carbazol‐9‐yl)ethyl] phosphonic acid (2PACz) as NiAc·4H O/2PACz aiming at overcoming limitations posed by conventional PEDOT:PSS one. Encouragingly, remarkable power conversion efficiency (PCE) 19.12% obtained for OSCs employing surpassing that devices HTL (17.59%), which ranked among highest ones OSCs. This improvement attributed to appropriate work function, enhanced hole mobility, facilitated exciton dissociation efficiency, lower recombination loss O/2PACz‐based Furthermore, exhibit superior stability compared their PEDOT:PSS‐based counterparts. Of significant note, demonstrates broad generality, boosting PCE PM6:PY‐IT PM6:Y6‐based from 16.47% 16.79% (with analogs HTLs) 17.36% 17.57%, respectively. These findings underscore substantial potential advancing OSCs, offering improved performance stability, thereby opening avenue highly efficient reliable energy harvesting technologies.
