Abstract Due to the limited interface contact and weak interfacial interaction, planar heterojunction perovskite solar cells (PSCs) have space for further improvement. Herein, a structural chemical crosslinking is proposed constructed by introducing an extra layer, which blends tin dioxide (SnO 2 ) nanoparticles with chloride salts. Since incorporated materials can be dissolved during fabrication of perovskite, quality films improved, leading larger grain size reduced trap‐state density....
This study demonstrates the transformative impact of incorporating poly(vinylidene fluoride-co-trifluoroethylene) P(VDF-TRFE) as an additive in hole transport layer (HTL) 2,2′,7,7′-Tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene (Spiro-OMeTAD). The forms resilient coordination bonds with 4-tert-butylpyridine (TBP) and lithium bis(trifluoromethanesulfonyl)imide additives, which mitigates TBP evaporation improves Spiro-OMeTAD film quality. In addition, we observed improvements...
So far, one of the fundamental limitations silver nanowires (Ag NWs) is high contact resistance among their junctions. Moreover, a rough surface due to its random arrangement inevitable electrical short when nanowire-based electronics driving. To improve resistance, we suggest that particle shape nanocrystals are intentionally reduced at junctions by localized joule-heat reduction approach from ions. Via reductions, nanoparticles effectively weld junction's areas, resulting in 19% decrease...
A controlled amount of excess lead iodide (PbI2) in the perovskite precursor has been widely used solar cells (PSCs) to enhance device's performance by passivating defects. However,...
Hybrid organic-inorganic perovskite solar cells (PSCs) offer a highly promising solution for achieving low-cost, high-performance photovoltaics. However, to accelerate the development of PSC technology, it is critical quantify local performance losses and identify problematic regions across device. Obtaining spatially resolved information essential not only device fabrication but also material optimization, particularly when scaling up technology. In this work, we propose an imaging-based...
Perovskite solar cell (PSC) technology is a promising candidate for space applications because of its high power‐to‐weight ratio, low‐cost fabrication process, and good tolerance to high‐energy particle radiation. In this work, perovskite films resultant high‐efficiency PSCs are assessed under 10 MeV proton radiation at fluences in the range 1e12–1e14 p cm −2 , which equivalent 1 100 years geostationary orbit (GEO) without any shielding or cover. For first time, void formation material...
We develop a facile route to the scalable fabrication of flexible reattachable ionomer nanopatterns (RAINs) by continuous nanoinscribing and low-temperature roll imprinting, which are repeatedly attachable detachable from arbitrarily shaped surfaces. First, sequentially performing over polymer substrate along multiple directions, we readily create multidimensional nanopattern, otherwise demands complex nanofabrication. After its transfer an elastomer pad for use as soft nanoimprinting stamp,...
Abstract Luminescent coupling (LC) is a key phenomenon in monolithic tandem solar cells. This study presents nondestructive technique to quantitatively evaluate the LC effect, addressing gap existing predictions made by optical modeling. The method involves measuring ratio of photons emitted from high bandgap top cell that escape through rear, contributing additional current bottom cell, and those escaping front side cell. findings indicate analyzed perovskite/silicon cells, more than 85%...
Perovskite solar cells (PSCs) are studied in low-intensity low-temperature (LILT) conditions before and after low energy proton irradiation to characterize device performance at deep space mission-relevant light intensities temperatures.
Perovskite solar cell technology offers a promising power option for space applications due to its potential properties of high power‐to‐weight ratios and space‐radiation tolerance. Herein, new simulation‐based method is introduced predict the degradation perovskite cells under proton radiation. The approach uses ion scattering simulations generate depth‐dependent defect profiles as function energy fluence, which are then incorporated into optoelectronic degradation. study impact...
The bottom perovskite with the hole transport layer (HTL) in inverted solar cells (PSCs) interface has received little attention due to challenges like interlayer dissolution during deposition. And voids at perovskite/HTL can degrade cell performance. This work introduces a two‐dimensional (2D) between and poly (N, N′‐bis‐4‐butylphenyl‐N, N′‐bisphenyl) benzidine (Poly‐TPD) HTL using mixed solution of 4‐methylphenethylammonium chloride (4M‐PEA‐Cl), methylammonium iodide (MA‐I),...
