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
perovskites shine a bright light on achieving high-efficiency and low-cost tandem solar cells (TSCs)1,2. All-perovskite TSCs, including mechanically stacked four-terminal (4-T) tandem and monolithic two-terminal (2-T) tandem configurations, could surpass the Shockley–Queisser...
The efficiency of all-perovskite tandem solar cells has surpassed that of single-junction perovskite solar cells, yet they still suffer from interfacial non-radiative recombination losses. Charge-selective materials that can reduce such losses as well as fabrication cost “applicable” to both subcells...
The improvements are attributed to increased built-in potential, reduced surface recombination, and enhanced photon absorption. These results demonstrate the potential of WSe2-enhanced Cu3VSe4 PV cells for next-generation high-efficiency thin-film solar technologies....
Radiative cooling (RC) technologies channel excess heat into outer space or cooler environments, potentially mitigating high temperatures in the built environment. However, despite progress in research, the transition from laboratory breakthroughs to widespread practical deployment remains challenging. In this...
To obtain high efficiency in PSC, organic-inorganic hybrid perovskite is sandwiched in a typical device configuration (either regular or inverted PSC configuration) by charge transporting materials and corresponding electrodes as depicted in Fig. 1, where ETM, HTM represent electron transporting material...
( arkani-hamed 2012 ; arkani-hamed and olson 2010 ; roberts and arkani-hamed 2014 ). 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 ...
P‐9.1: Bifacial Passivation towards Efficient FAPbBr3‐based Inverted Perovskite Light‐emitting DiodesPerovskite light-emitting diode (PeLEDs) is a promising technology in the application of display, due to its tunable emission wavelength, wide color gamut, and high photo-luminescence quantum yield ...
The main bottlenecks limiting the photovoltaic performance and stability of inverted perovskite solar cells (PSCs) are trap-assisted non-radiative recombination losses and photochemical degradation at the interface between perovskite and charge-transport
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...
