Abstract Perovskite solar cells (PSCs) have rapidly developed and achieved power conversion efficiencies of over 20% with diverse technical routes. Particularly, planar‐structured PSCs can be fabricated low‐temperature (≤150 °C) solution‐based processes, which is energy efficient compatible flexible substrates. Here, the efficiency stability planar are enhanced by improving interface contact between SnO 2 electron‐transport layer (ETL) perovskite layer. A biological polymer (heparin...
Traps in the photoactive layer or interface can critically influence photovoltaic device characteristics and stabilities. Here, traps passivation retardation on degradation for methylammonium lead trihalide (MAPbI3 ) perovskite solar cells enabled by a biopolymer heparin sodium (HS) interfacial is investigated. The incorporated HS boosts power conversion efficiency from 17.2 to 20.1% with suppressed hysteresis Shockley-Read-Hall recombination, which originates primarily of near between...
Abstract Perovskite solar cells have reached a power conversion efficiency over 25%, and the engineering of interface between perovskite hole transport layer (HTL) has been crucial to achieve high performance. Here we design bifunctional molecule CBz-PAI with carbazole-triphenylamine phenylammonium iodide units passivate defects at perovskite/HTL interface. Owing favourable energy level alignment perovskite, acts as shuttle HTL. This minimizes difference quasi-Fermi splitting or ‘internal’ V...
High-quality perovskite light harvesters and robust organic hole extraction layers are essential for achieving high-performing solar cells (PSCs). We introduce a phosphonic acid-functionalized fullerene derivative in mixed-cation perovskites as grain boundary modulator to consolidate the crystal structure, which enhances tolerance of film against illumination, heat, moisture. also developed redox-active radical polymer, poly(oxoammonium salt), that can effectively p-dope hole-transporting...
Mechanical failure and chemical degradation of device heterointerfaces can strongly influence the long-term stability perovskite solar cells (PSCs) under thermal cycling damp heat conditions. We report chirality-mediated interfaces based on
Abstract The self‐assembled hole transporting molecules (SAHTMs) bearing anchoring groups have been established as the layers (HTLs) for highly efficient p–i–n perovskite solar cells (PSCs), yet their stability and engineering at molecular level remain challenging. A topological design of anisotropic aligned SAHTM‐based HTLs operationally stable PSCs that exhibit exceptional solar‐to‐electric power conversion efficiencies (PCEs) is demonstrated. judiciously designed multifunctional comprise...
Carbazole-based self-assembled monolayers (SAMs) at the interface between metal-halide perovskite (MHP) and transparent conducting oxide (TCO) serve function of hole-transport layers in p-i-n "inverted" solar cells (PSCs). Here we show that use an iodine-terminated carbazole-based SAM increases interfacial mechanical adhesion dramatically (2.6-fold) this is responsible for substantial improvements morphology, photocarrier transport, operational stability. While improved morphology...
The adoption of perovskite solar cells (PSCs) requires improved resistance to high temperatures and temperature variations. Hole-selective self-assembled monolayers (SAMs) have enabled progress in the performance inverted PSCs, yet they may compromise stability owing desorption weak interfacial contact. Here we developed a bilayer by covalently interconnecting phosphonic acid SAM with triphenylamine upper layer. This polymerized network, formed through Friedel–Crafts alkylation, resisted...
Bacillus subtilis var. natto N21 (Bac; for greater proteolytic capacity) and Saccharomyces cerevisiae Y10 (Sac; acidic were applied to produce a 2-stage combined fermentation feed. This study investigated whether the enhancement of Bac+Sac fermented feed on broiler growth performance was due probiotics per se or process. Trial 1 included 1-d-old chicks (n =144) randomly assigned control, water added (same as in feed, 23%), (FBac+Sac) treatments with 4 replicates. 2 21-d-old chickens = 12)...
Meteorus pulchricornis is a preponderant parasitic wasp of various lepidopteran pests. The extensive application broad-spectrum insecticides usually causes serious threats to the olfactory recognition nontarget insects such as parasitoid wasps. However, binding mechanism odorant-binding proteins (OBPs) in wasps remains unknown. Herein, we find that MpulOBP6 protein had strong affinity three (phoxim, chlorpyrifos, and chlorfenapyr). Results computational simulations revealed hydrophobic...
Mechanical residual stresses within multilayer thin-film device stacks become problematic during thermal changes because of differing expansion and contraction the various layers. Thin-film photovoltaic (PV) devices are a prime example where this is concern temperature fluctuations that occur over long deployment lifetimes. Here, we show control stress halide perovskite by use an alkyl-ammonium additive. This additive approach reduces strain to near-zero at room prevents cracking...
A multifunctional interface modulator GO/(CsPbBr 3 QD) composite decreases resistive losses of perovskite solar modules by enhanced charge transport and decreased carrier recombination, as well inhibiting ion/molecule diffusion.
For fabricating high-performance perovskite solar cells (PSCs) and modules, it is crucial to obtain high-quality (PVSK) films efficient interfacial charge transport. Here, we introduce a synergistic strategy combining [6,6]-4-fluorophenyl-C61-butyric acid (FPAC60) self-assembled monolayer (SAM) bis-adduct 2,5-(dimethyl ester) C60 fulleropyrrolidine (bis-DMEC60) additive an device. The FPAC60 SAM can not only promote transport passivate defects at the SnO2/PVSK buried interface but also serve...
To enhance n-i-p perovskite solar cell (PSC) performance, we optimized the hole transport material (HTM) by using a cost-effective N,N′-bicarbazole-based molecule, BCzSPA, with 3D conjugated extended "L"-type configuration, to fix molecular packing model and charge hopping channel. By implementing mesoscale tailoring strategies order stacking of have significantly realized dense mosaic self-assembly intermolecular coupling multichannel properties. The proper incorporation heteroatom-promoted...
Based on control of the perovskite film thickness, we investigate temperature-dependent charge carrier transport, recombination, traps, and solar cell behavior based methylammonium lead triiodide films.
Based an additive process, we demonstrate control over the crystallographic growth kinetics in polycrystalline perovskites with achieving high efficiency and stable perovskite solar cells.
Although the power conversion efficiency (PCE) of organometal halide perovskite solar cells (PSCs) has reached 25.2%, control crystallization process and its impact on film quality is still one main challenges.
