“…Figure S6 shows the top-view SEM micrographs of the bare ITO electrodes and the PCBP, PTCB, and PTPTCzSiOH films electrodeposited on the ITO surface. The surface of the ITO was smooth, with little roughness (see Figure S6a ) [ 71 ]. In general, the morphology of the polymer-modified ITO electrodes was the same as that of the bare electrode, indicating that the film was quite thin.…”

The persistence and potential toxicity of emergent pollutants pose significant threats to biodiversity and human health, emphasizing the need for sensors capable of detecting these pollutants at extremely low concentrations before treatment. This study focuses on the development of glassy carbon electrodes (GCEs) modified by films of poly-tris(4-(4-(carbazol-9-yl)phenyl)silanol (PTPTCzSiOH), poly-4,4′-Di(carbazol-9-yl)-1,1′-biphenyl (PCBP), and poly-1,3,5-tri(carbazol-9-yl)benzene (PTCB) for the detection of metronidazole (MNZ) in aqueous media. The films were characterized using electrochemical, microscopy, and spectroscopy techniques, including scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). Monomers were electropolymerized through cyclic voltammetry and chronoamperometry techniques. Computational methods at the B3LYP/def2-TZVP level were employed to investigate the structural and electrochemical properties of the monomers. The electrochemical detection of MNZ utilized the linear sweep voltammetry technique. Surface characterization through SEM and XPS confirmed the proper electrodeposition of polymer films. Notably, MPN-GCEs exhibited higher detection signals compared to bare GCEs up to 3.6 times in the case of PTPTCzSiOH-GCEs. This theoretical study provides insights into the structural, chemical, and electronic properties of the polymers. The findings suggest that polymer-modified GCEs hold promise as candidates for the development of electrochemical sensors.

“…In order to explore all the three aforementioned tandem architectures, we investigate both the direct (n-i-p) and inverted (p-i-n) planar PSC architectures that allow us to guarantee the proper connection of terminals. In all the simulations we will consider ITO-coated glass substrates as they allow the highest device transparency due to the reduction of optical losses, [19][20][21] which is shown by comparing ITO and fluorine-doped tin oxide (FTO) (see Figure S2, Supporting Information).…”

Design of Highly Efficient Semitransparent Perovskite/Organic Tandem Solar Cells

Solar cells transparent in the visible range are highly requested for integration in see-through photovoltaic (PV) applications such as building glass façades or green-house roofs. The development of advanced transparent PV can fully exploit the tandem technology where the top cell absorb the near-ultraviolet solar spectrum while the bottom the near-infrared part. In this work we consider a possible implementation of this tandem PV paradigm, namely the tandem structure composed by a high-band gap halide perovskite solar cell and a low-band gap organic solar cell. Electro-optical simulation results based on parameters calibrated on experimental data shows that efficiency of 15% can be achieved with Average Visual Transmittance above 50%. This can be obtained considering the halide perovskite with mixed Clorine and Bromine anions, a non-fullerene based bulk heterojunction, a well calibrated light management and a three terminal configuration of the tandem.

Herein, we report a solution-processable memristive device based on bismuth vanadate (BiVO 4 ) and titanium dioxide (TiO 2 ) with gallium-based eutectic gallium−indium (EGaIn) and gallium−indium-tin alloy (GaInSn) liquid metal as the top electrode. Scanning electron microscopy (SEM) shows the formation of a nonporous structure of BiVO 4 and TiO 2 for efficient resistive switching. Additionally, the gallium-based liquid metal (GLM)contacted memristors exhibit stable memristor behavior over a wide temperature range from −10 to +90 °C. Gallium atoms in the liquid metal play an important role in the conductive filament formation as well as the device's operation stability as elucidated by I−V characteristics. The synaptic behavior of the GLM-memristors was characterized, with excellent long-term potentiation (LTP) and longterm depression (LTD) linearity. Using the performance of our device in a multilayer perceptron (MLP) network, a ∼90% accuracy in the handwriting recognition of modified national institute of standards and technology database (MNIST) was achieved. Our findings pave a path for solution-processed/GLM-based memristors which can be used in neuromorphic applications on flexible substrates in a harsh environment.
