Article Abstract
Interfacial energy loss is a critical challenge in achieving high-efficiency organic solar cells (OSCs), primarily due to mismatched energy levels and inefficient charge collection. Herein, a bifunctional interface engineering strategy is proposed, employing an ethanol/o-difluorobenzene (EtOH/o-DFB) dual-solvent system for phosphotungstic acid (HPWO) processing. During film formation, o-DFB regulates HPWO crystallization by suppressing excessive aggregation, while enabling in situ ITO fluorination through the adsorbed o-DFB. This synergistic approach simultaneously mitigates the trap-assisted nonradiative recombination at the hole transport layer while enhancing the electrode work function, resulting in better ohmic contact, minimized trap-state densities, and improved energy level alignment at the electrode/active layer interface. The effectiveness of this strategy is demonstrated across multiple active layer systems. Remarkable power conversion efficiencies of 19.55%, 20.07%, and 20.57% are achieved for PM6/L8-BO, D18/L8-BO, and D18/BTP-eC9-based OSCs, respectively. Notably, the 20.57% PCE represents one of the highest efficiencies reported to date for OSCs, highlighting the potential of this bifunctional interface engineering strategy in advancing high-performance organic photovoltaics.

The sliding motion of aqueous droplets on hydrophobic surfaces leads to charge separation at the trailing edge, with implications from triple-line friction to hydrovoltaic energy generation. Charges deposited on the solid surface have been attributed to ions or electrons ripped off from the liquid drop. However, the dynamics and exact physicochemical nature of these surface-trapped charges remains poorly explored.

Understanding the intricate relationship between land use/land cover (LULC) transformations and land surface temperature (LST) is critical for sustainable urban planning. This study investigates the spatiotemporal dynamics of LULC and LST across Delhi, India, using thermal data from Landsat 7 (2001), Landsat 5 (2011) and Landsat 8 (2021) resampled to 30-m spatial resolution, during the peak summer month of May. The study aims to target three significant aspects: (i) to analyse and present LULC-LST dynamics across Delhi, (ii) to evaluate the implications of LST effects at the district level and (iii) to predict seasonal LST trends in 2041 for North Delhi district using the seasonal auto-regressive integrated moving average (SARIMA) time series model.

Wearable sensors integrated with deep learning techniques have the potential to revolutionize seamless human-machine interfaces for real-time health monitoring, clinical diagnosis, and robotic applications. Nevertheless, it remains a critical challenge to simultaneously achieve desirable mechanical and electrical performance along with biocompatibility, adhesion, self-healing, and environmental robustness with excellent sensing metrics. Herein, we report a multifunctional, anti-freezing, self-adhesive, and self-healable organogel pressure sensor composed of cobalt nanoparticle encapsulated nitrogen-doped carbon nanotubes (CoN CNT) embedded in a polyvinyl alcohol-gelatin (PVA/GLE) matrix.

Slippery liquid-infused porous surfaces (or "SLIPS") can prevent bacterial surface fouling, but they do not inherently possess the means to kill bacteria or reduce cell loads in surrounding media. Past reports show that the infused liquids in these materials can be leveraged to load and release antimicrobial agents, but these approaches are generally limited to the use of hydrophobic agents that are soluble in the infused oily phases. Here, we report the design of so-called "proto-SLIPS" that address this limitation and permit the release of highly water-soluble (or oil-insoluble) agents.

Photomultiplication-type organic photodetectors (PM-type OPDs) have recently attracted attention. However, the development of polymer donors specifically tailored for this architecture has rarely been reported. In this study, we synthesized benzobisoxazole-based polymer donors incorporating alkylated π-spacers that simultaneously enhance photocurrent density () and suppress dark current density (), leading to high responsivity () and specific detectivity (*).
