Abstract Tuning the properties of non‐fullerene acceptors (NFAs) through halogenation, including fluorination and chlorination, represents one most promising strategies to boost performance organic solar cells (OSCs). However, it remains unclear how F Cl choice influences molecular packing between small‐molecule polymeric acceptors. Here, a series with different amounts types halogenation is synthesized, effects chlorination are investigated. It found that chlorinated lead longer exciton...
An energy-efficient nonvolatile intelligent processor (NIP) is proposed for battery-less energy harvesting system. This NIP employs RRAM-based logics (NVL) with self-write-termination (SWT) scheme and low-power processing-in-memory (PIM) to achieve computing against frequent power-off situations. test chip was fabricated in 150nm CMOS process using HfO RRAM. achieves 462GOPs/J efficiency at 20MHz clock frequency, showing 13× performance improvement over state-of-the-arts. work presents the...
The emergence of Y-series non-fullerene acceptors (NFAs) has inspired the development various materials for high-performance organic solar cells (OSCs). In this work, a novel asymmetric NFA named Y6-1OBO bearing branched alkyl and alkoxy side chains was designed synthesized. When diiodomethane selected as solvent additive, Y6-1OBO-based devices achieved an efficiency 18.02% with open-circuit voltage 0.93 V fill factor 77.1%, which is much higher than that Y6-1O-based (16.81%). effects...

Herein, 1,4‐Dibromobenzene (DBB) and 1,4‐Difluoro‐2,5‐dibromobenzene (DFBB) are introduced into OSCs. Theoretical calculations indicate that DFBB a higher electrostatic potential extremum stronger σ‐holes interaction compared to DBB, enabling more...
Nonvolatile flip-flops (nvFFs) enable frequent-off processors to achieve fast power-off and wake-up time while maintaining critical local computing states through parallel data movement between volatile FFs nonvolatile memory (NVM) devices. However, current nvFFs face challenges in large store energy ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\text{E}_{\mathrm {S}}$ </tex-math></inline-formula> )...

Fluorination of polymer donors has demonstrated considerable potential for boosting the performance organic solar cells (OSCs). However, achieving optimal requires careful management fluorine levels, as excessive fluorination may adversely affect device efficiency. In this study, we introduce a controlled number atoms into alkyl side chains to optimize their temperature-dependent aggregation and intermolecular interactions. Four polymers (PTF0, PTF1, PTF2, PTF3) with reduced synthetic...
With an ever-increasing demand for energy efficiency, processors with instant-on and zero leakage features are highly appreciated in harvesting as well "normally off" applications. Recently, zero-standby power fast switching nonvolatile (NVPs) have been proposed based on emerging memories (NVMs), such ferroelectric RAM or spin-transfer-torque magnetic RAM. However, previous NVPs store all data to NVM upon every interruption, resulting high-energy consumption degraded endurance. This paper...
ReRAM-based processing-in-memory (PIM) architecture is a promising solution for deep neural networks (NN), due to its high energy efficiency and small footprint. However, traditional PIM has use separate crossbar array store either positive or negative (P/N) weights, which limits both area efficiency.

Physical adversarial patches printed on clothing can easily allow individuals to evade person detectors. However, most existing patch generation methods prioritize attack effectiveness over stealthiness, resulting in that are aesthetically unpleasing. Although using generative networks or diffusion models produce more natural-looking patches, they often struggle balance stealthiness with and lack flexibility for user customization. To address these challenges, we propose a novel...

This paper presents a compare-and-select (CaS) error tolerant scheme for nonvolatile processors (NVPs). Nonvolatile flip-flops (NVFFs), used in NVPs suffer from the faults caused by devices. Conventional methods are designed centralized memory macros and inefficient distributed NVFFs. In our CaS scheme, we use read-write-read-compare strategy to get map of NVFFs find out NVFF bits with faults. Then fully functional selected store data discarded.
