The performance of perovskite solar cells with inverted polarity (p-i-n) is still limited by recombination at their electron extraction interface, which also lowers the power conversion efficiency (PCE) p-i-n perovskite-silicon tandem cells. A MgF x interlayer thickness ~1 nanometer perovskite/C 60 interface favorably adjusts surface energy layer through thermal evaporation, facilitates efficient and displaces C from to mitigate nonradiative recombination. These effects enable a champion...
Abstract Recent achievements in amorphous/crystalline silicon heterojunction (SHJ) solar cells and perovskite/SHJ tandem place hydrogenated amorphous (a-Si:H) at the forefront of photovoltaics. Due to extremely low effective doping efficiency trivalent boron tetravalent silicon, light harvesting aforementioned devices is limited by their fill factors (FFs), a direct metric charge carrier transport. It challenging but crucial develop highly conductive doped a-Si:H with minimal FF losses. Here...
Defect passivation is crucial to enhancing the performance of perovskite solar cells (PSCs). In this study, we successfully synthesized a novel organic compound named DPPO, which consists double phosphonate group. Subsequently, incorporated DPPO into solution. The presence P═O group interacting with undercoordinated Pb2+ yielded film superior crystallinity, greater crystal orientation, and smoother surface. Additionally, addition can passivate defect states enhance upper layer energy level...
Relying on weak cross-Kerr nonlinearities, we propose a nearly deterministic generation scheme of the three-photon polarization-entangled perfect $W$ state which can be applied to teleportation an unknown single-photon and has robust entanglement against loss one photon them. Three photons entangle together by virtue bus function coherent serving as intermediate among In scheme, three processes are executed successively two kinds modules inserted into circuit, where homodyne measurement...
Shortwave infrared colloidal quantum dots (SWIR-CQDs) are semiconductors capable of harvesting across the AM1.5G solar spectrum. Today's SWIR-CQD cells rely on spin-coating; however, these films exhibit cracking once thickness exceeds ∼500 nm. We posited that a blade-coating strategy could enable thick QD films. developed ligand exchange with an additional resolvation step enabled dispersion SWIR-CQDs. then engineered quaternary ink combined high-viscosity solvents short stabilizing ligands....
Increasing the power conversion efficiency (PCE) of colloidal quantum dot (CQD) solar cells has relied on improving passivation CQD surfaces, enhancing coupling and charge transport, advancing device architecture. The presence hydroxyl groups nanoparticle surface, as well dimers-fusion between CQDs-has been found to be major source trap states, detrimental optoelectronic properties performance. Here, we introduce a reconstruction step that decreases surface dimers simultaneously. We explored...
Abstract The benchmark tin oxide (SnO 2 ) electron transporting layers (ETLs) have enabled remarkable progress in planar perovskite solar cell (PSCs). However, the energy loss is still a challenge due to lack of “hidden interface” control. We report novel ligand-tailored ultrafine SnO quantum dots (QDs) via facile rapid room temperature synthesis. Importantly, QDs ETL with multi-functional terminal groups situ refines buried interfaces both and transparent electrode enhanced interface...
Abstract The heterogeneity of perovskite film crystallization along the vertical direction leads to voids and traps at buried interfaces, hampering both efficiency stability solar cells. Here, bovine serum albumin‐functionalized Au nanoclusters (ABSA), combined with heavy gravity, high surface charge density, strong interactions electron transport layer, are designed reconstruct interfaces for not only high‐quality crystallization, but also improved carrier transfer. ABSA macromolecules...
A theoretical scheme of quantum secure communication using a class three-particle W states is proposed. In the scheme, two communicators may communicate after they test security channel. The receiver can obtain secret message determinately if channel safe. present be realized without teleportation.
With the assistance of weak cross-Kerr nonlinearities, we present a preparation scheme four-photon polarization-entangled decoherence-free states, which can be used to construct minimal optical subspaces where logical qubit is fully protected against collective decoherence. To complete task, one spatial entanglement process, two polarization processes, and detecting process are applied. The fulfillments above processes contributed by nonlinear interaction between signal photons coherent...
The near-infrared (NIR) absorbing fused-ring electron acceptor, COi8DFIC, has demonstrated very good photovoltaic performance when combined with PTB7-Th as a donor in binary organic solar cells (OSCs). In this work, the NIR acceptor was added to state-of-the-art PBDBT-2F:IT4F-based third component, leading (i) an efficiency increase of ternary devices compared presence highly crystalline COi8DFIC and (ii) much-improved photostability under 1-sun illumination. transport properties were...
Fluorination has proven effective in increasing the absorption, downshifting energy levels, and enhancing crystallinity of high‐performance fused‐ring electron acceptors (FREAs). However, an in‐depth understanding effects fluorination is still lacking, as research efforts have mainly focused on power conversion efficiency (PCE). In addition, FREAs rarely been reported all‐small‐molecule organic solar cells (ASM OSCs). Herein, systematically studied ASM OSCs using popular FREA 2,2′‐((2 Z ,2′...
