Towards 26% efficiency in inverted perovskite solar cells via interfacial flipped band bending and suppressed deep-level trapsThe strong nonradiative recombination loss of inverted PSCs at the surface and at the perovskite/C60 interface has limited the open-circuit voltage (Voc) and fill factor (FF...
process, enabling fabrication of efficient single-junction perovskite solar cells (PVSCs) and all-perovskite tandem solar cells. As a result, the best PCEs of 21.51% and 18.58% for single-junction low-Egand wide-EgPVSCs are achieved and thus ensure the fabrication of 25.15% efficiency 4-...
Halide perovskite materials have been extensively explored for their unique electrical, optical, magnetic, and catalytic properties. Most notably, solar cells based on perovskite thin films have improved their power conversion efficiency from 3.8% to over 25% during the last 12 years. However, it is...
The voltage efficiency of the AELs was calculated assuming a Faradaic efficiency for the HER equal to 1, thereby:voltageefficiency=Erev/Ecellin which Erev (1.18 V) is the thermodynamic reversible voltage for water electrolysis, i.e., the minimum voltage required for the onset of water ...
BaBiO3 Perovskite Complex oxide Single crystals Thin films Breathing mode Topological insulator 1. Introduction The perovskite BaBiO3 was studied extensively in the last five decades, and now it is receiving renewed attention. From a simple, purely ionic picture of the unit cell formula, one would...
A robust, chemically stable and low-temperature-processed hole transporting layer (HTL) is essential for building high-efficiency Sn-Pb solar cells and perovskite tandem solar cells. Here, we explore a room-temperature-processed NiOx (L-NiOx) HTL based on nanocrystals (NCs) for Sn-Pb PSCs. ...
Thus, core impact heating could inhibit the dynamo generation during a timescale that is governed by the efficiency of the surrounding mantle to extract the impact induced core thermal anomaly (from several kyr up to 100 Myr). Numerical simulations of mantle convection may shed light on the ...
Solid-state perovskite solar cells (PSCs) were first discovered in 2012, where a power conversion efficiency (PCE) of 9.7% was demonstrated along with stability for 500 h at ambient atmosphere. Since then, the PCEs of PSCs have increased amazingly to over 26%. Moreover, perovskite/silicon ...
in the efficiencies of 2D-perovskite solar cells with PCEs of up to 18.2% being reported for inverted (p–i–n) devices8. However, with 2D-perovskite solar cells, there might ultimately be a trade-off between stability and efficiency with the latter being affected by quantum confinement of ...
In recent, the quantum yield (QY) and stability of green quantum dots (QDs) have been significantly improved. However, most of the progresses were achieved by using alloyed QDs, and the control of green emission QDs still remains challenging. Herein, we report a novel method for synthesizing ...
