The strong activity of water molecules causes a series parasitic side reactions on Zn anodes in the aqueous electrolytes. Herein, we introduce silk fibroin (SF) as multifunctional electrolyte additive for zinc-ion (Zn-ion) batteries. secondary structure transformation SF from α-helices to random coils electrolytes allows them break hydrogen bond network among free and participate Zn2+ ion solvation structure. released [Zn(H2O)4(SF)]2+ sheath appear be gradually adsorbed surface situ form...
Abstract Organolead halide perovskite is a newly emerging low-cost, solution-processable material with broadband absorption from the ultraviolet (UV) to visible (Vis) region, which has attracted great deal of interest in high-performance optoelectronic devices. However, some practicable applications need cover UV–Vis–NIR region for photoelectric conversion, task that remains significant challenge further extending toward near-infrared radiation (NIR) region. Here, best our knowledge, we...
Pentacene organic phototransistors (OPTs) modified by introducing C60 electrodes buffer layer were fabricated. Compared with conventional single-layer pentacene OPTs, the devices exhibited higher performance under illumination. Maximum photoresponsivity is 4.27 A/W at zero gate bias 0.2 mW cm−2, which six times than that of device and exceeds most OPTs reported recently in same conditions. The maximum photo/dark current ratio also 5 × 104. Meanwhile, could obtain lower threshold voltage...
Trap‐induced current multiplication has received tremendous attention in organic photodetectors because it is not required for a pre‐amplifier circuit to read weak photocurrent signals. However, plausible correlation between energy‐distin‐guishable trap states and device performance been established guiding the design, task that remains significant challenge. Here, we propose an ingenious strategy demonstrate by engineering ultrathin fullerene (C 60 ) film as hole or barrier layer, which...
In conventional photosensitive organic field-effect transistors (FETs) (OFETs) (photo-OFETs) based on p-type semiconductors, high work function metals such as Au are generally used source/drain electrodes, whose photosensitivity is low. We report the performance improvements of photo-OFETs palladium phthalocyanine (PdPc) by using Al source and drain electrodes. It concluded that dark currents photo-OFET PdPc with electrodes (denoted Al-PdPc device) about only one-thousandth Au-PdPc device)....
High-performance organic broadband photomemory transistors by photogenerated minority carrier trapping and accumulation kinetics.
For organic films, remarkably enhanced red–NIR broad spectral absorption was achieved via the incorporation of gold nanoparticles (AuNPs) using a simple and facile preparation. The relevant thermal evaporation method has produced size-controllable AuNPs in range 0–20 nm diameter. potential use localized surface plasmon resonance (LSPR) photosensitive diodes (OPDs) as sensitive broadband sensors discussed this context. Here we showed that, by combining heterojunctions with plasmonic AuNPs,...
Near-infrared Organic upconversion devices (NIR OUDs), which convert incident low-energy NIR photons to high-energy visible photons, have many advantages such as simple fabrication process, low cost, flexibility, large area fabrication, and inherent pixel-less imaging, play important roles in night vision security applications. In general, OUDs can be realized by integrating the organic photosensitive layer sensitizer with active layers of normal well inverted light-emitting diodes (OLEDs)...

Abstract Broadband photodetection is central to spectroscopy, imaging, and sensing in modern science technology. However, traditional devices suffer from a higher dark current because as‐adopted photoactive semiconductors tend be accompanied by large noise output due conductivity, resulting low sensitivity detectivity. The utilization of photon manipulation as enhancing light–matter interaction on deep subwavelength scale provides fascinating opportunity achieve photocurrent while keeping...
Weak light response of organic photodetectors has fascinating potentials in fields modern science and technology. However, their photoresponsivity is hindered by poor photocarrier excitation transport. Decorating active-layer surface with plasmonic nanometals considered a viable strategy to address this issue. Here, we demonstrate nanogold decorated phototransistor achieving remarkable enhancement photoresponsivity. Meanwhile, the photoresponsive range broadened 4 orders magnitude. The...
