The rapid growth of Location-based Social Networks (LBSNs) provides a vast amount check-in data, which facilitates the study point-of-interest (POI) recommendation. majority existing POI recommendation methods focus on four aspects, i.e., temporal patterns, geographical influence, social correlations and textual content indications. For example, user's visits to locations have patterns users are likely visit POIs near them. In real-world LBSNs such as Instagram, can upload photos associating...
Organic solar cells (OSCs) are promising candidates for next-generation photovoltaic technologies, with their power conversion efficiencies (PCEs) reaching 19%. However, the typically used spin-coating method, toxic halogenated processing solvents, and conventional bulk-heterojunction (BHJ), which causes excessive charge recombination, hamper commercialization further efficiency promotion of OSCs. Here, a simple but effective dual-slot-die sequential (DSDS) strategy is proposed to address...
Efficient exciton diffusion and charge transport play a vital role in advancing the power conversion efficiency (PCE) of organic solar cells (OSCs). Here, facile strategy is presented to simultaneously enhance exciton/charge widely studied PM6:Y6-based OSCs by employing highly emissive trans-bis(dimesitylboron)stilbene (BBS) as solid additive. BBS transforms sites from more H-type aggregate into J-type aggregate, which benefits resonance energy transfer for PM6 Y6. Transient gated...
Abstract Sequential deposition of the active layer in organic solar cells (OSCs) is favorable to circumvent existing drawbacks associated with controlling microstructure bulk‐heterojunction (BHJ) device fabrication. However, how processing solvents impact on morphology during sequential processes still poorly understood. Herein, high‐efficiency OSCs are fabricated by a blade coating (SBC) through optimization evolution process induced solvents. It demonstrated that performance highly...
Abstract Power-conversion-efficiencies (PCEs) of organic solar cells (OSCs) in laboratory, normally processed by spin-coating technology with toxic halogenated solvents, have reached over 19%. However, there is usually a marked PCE drop when the blade-coating and/or green-solvents toward large-scale printing are used instead, which hampers practical development OSCs. Here, new series N -alkyl-tailored small molecule acceptors named YR-SeNF same molecular main backbone developed combining...

Abstract Sequential deposition has great potential to achieve high performance in organic solar cells due the resulting well‐controlled vertical phase separation. In this work, double bulk heterojunction are fabricated by sequential‐blade cast ambient conditions. Probed situ grazing incidence X‐ray diffraction and UV–vis absorption measurements, seq‐blade system exhibits a different tendency from each of binary films during film formation process.

An assumption widely used in recent neural style transfer methods is that image styles can be described by global statics of deep features like Gram or covariance matrices. Alternative approaches have represented decomposing them into local pixel patches. Despite the progress, most existing treat semantic patterns uniformly, resulting unpleasing results on complex styles. In this paper, we introduce a more flexible and general universal technique: multimodal (MST). MST explicitly considers...
Abstract As a predominant fabrication method of organic solar cells (OSCs), casting bulk heterojunction (BHJ) structure presents overwhelming advantages for achieving higher power conversion efficiency (PCE). However, long‐term stability and mechanical strength are significantly crucial to realize large‐area flexible devices. Here, controlling blend film morphology is considered as an effective way toward co‐optimizing device performance, stability, properties. A PCE 12.27% P‐i‐N‐structured...
Image harmonization aims to improve the quality of image compositing by matching "appearance" (e.g., color tone, brightness and contrast) between foreground background images. However, collecting large-scale annotated datasets for this task requires complex professional retouching. Instead, we propose a novel Self-Supervised Harmonization framework (SSH) that can be trained using just "free" natural images without being edited. We reformulate problem from representation fusion perspective,...

The colorless, transparent, highly homogeneous, show significantly improved stability than...
Conventional organic solar cell (OSC) systems have significant energy offsets between the donor and acceptor both at highest occupied molecular orbital (HOMO) lowest unoccupied (LUMO) levels. Because of this, in a bulk heterojunction (BHJ) system, electrons typically transport acceptors, whereas holes donors. It is not favorable for to hop back forth because hopping energetically disfavored. In such conventional OSC systems, addition polymer films should reduce electron mobility. this study,...
In contrast to classical bulk heterojunction (BHJ) in organic solar cells (OSCs), the quasi-homojunction (QHJ) with extremely low donor content (≤10 wt.%) is unusual and generally yields much lower device efficiency. Here, representative polymer donors nonfullerene acceptors are selected fabricate QHJ OSCs, a complete picture for operation mechanisms of high-efficiency devices illustrated. PTB7-Th:Y6 at donor:acceptor (D:A) ratios 1:8 or 1:20 can achieve 95% 64% efficiency obtained from its...
