Kesterite Cu 2 ZnSn(S,Se) 4 (CZTSSe) solar cells suffer from significant open-circuit voltage ( V OC ) deficits due to severe interfacial and bulk recombination, restricting their power conversion efficiency (PCE) far below the Shockley-Queisser limit. This work proposes a low-temperature annealing strategy during ITO sputtering (SA) to synergistically address these challenges. The temperature applied during ITO sputtering not only improves the crystallinity, carrier concentration, and optical transmittance of the ITO layer but also promotes the diffusion of In from ITO into both CdS and CZTSSe layers. Consequently, lattice matching at the CZTSSe/CdS interface is optimized, enabling epitaxial growth. And a favorable ITO/In:CdS/In&Cd:CZTSSe structure with optimal band alignment is obtained. As a result, a champion device with a PCE of 14.29% was achieved. The SA-treating also enabled the CZTSSe solar cells to achieve the highest V OC reported to date, exceeding 590 mV. This underscores the essential role of SA processing in optimizing interface engineering and suppressing defects, thus promoting the development of low-cost, high-performance kesterite photovoltaics.

Inkjet printing presents a promising route for the scalable, high-resolution, and low-cost fabrication of functional oxide thin films; however, the design of robust inks capable of producing uniform, stable, and high-temperature-resistant oxide films remains highly challenging. Here, a highly stable precursor-based ink system for inkjet printing of ITO/In₂O₃ thin films is developed. By precisely tuning the mixed solvent ratio (EG:2-ME) and additive (EC) concentration, the rheological properties, jetting stability, and film uniformity are synergistically optimized, effectively suppressing the coffee-ring effect and improving surface morphology and structural density. The developed ink demonstrates good long-term storage stability and reproducibility, maintaining consistent chemical composition, particle size distribution, and thin-film performance over multiple batches and prolonged storage (120 days). Flexible thermoelectric films printed with this ink show reliable stability and repeatability of thermoelectric response over a broad temperature range (−196 to 848 °C), stable operation up to 100 h and under 50 thermal cycles at 800 °C. This work provides a reliable, scalable, and broadly applicable ink strategy for digital additive manufacturing of functional oxide films, contributing to the fabrication of flexible and devices for high-temperature sensing applications.

Flexible perovskite solar cells (f-PSCs) have achieved significant success. However, high-quality tin dioxide (SnO2) electron transport layers (ETLs) fabricated via chemical bath deposition (CBD) have not been achieved on flexible PEN/ITO substrates. This limitation is primarily due to the corrosion of the poor-quality ITO layer by the strongly acidic CBD solution. Here, we analyzed the reasons for the poor corrosion resistance of ITO films on PEN substrate from multiple perspectives, such as element composition, microstructure, and crystallinity. Then, we proposed a modified CBD method for SnO2 films suitable for flexible PEN/ITO substrates. We employed SnCl2·2H2O as the tin source and regulated the pH of the CBD solution by NH3·H2O, which effectively avoided the corrosion of the ITO layer by the CBD solution and achieved high-quality SnO2 films on the ITO layers. Compared to the commercial SnO2 dispersion, the SnO2 films prepared by this method have smaller grains and higher transmittance. As a result, we achieved an unprecedented power conversion efficiency (PCE) of 20.71% for f-PSCs fabricated on PEN/ITO substrates with SnO2 ETLs by CBD method. This breakthrough facilitates the development of high-performance f-PSCs by a low-cost and large-scale chemical bath deposition of high-quality ETLs on flexible substrates.

The development of organic memory devices, regarding factors such as structure construction, principle exploration, and material design, has become a powerful supplement to traditional silicon-based information storage. The in-situ growth of materials on substrate surfaces can achieve closer bonding between materials and electrodes. Bio-inspired by mussel chemistry, polydopamine (PDA) was self-assembled on a flexible substrate as a connecting layer, and 2-bromoiso-butyryl bromide (BiBB) was utilized as an initiator for the polymerization of an iridium complex via surface-initiated atom-transfer radical polymerization (SI-ATRP). A device with the structure of Al/PDA-PPy3Ir/ITO was constructed after the deposition of aluminum. The device exhibited a nonvolatile rewritable memory characteristic with a turn-on voltage of −1.0 V and an ON/OFF current ratio of 6.3 × 103. In addition, the memory performance of the Al/PDA-PPy3Ir/ITO device remained stable at bending states due to the intrinsic flexibility of the active layer, which can be expanded into the establishment of flexible memory devices. Spectroscopy and electrochemical characterization suggested that the resistive memory properties of the device stemmed from charge transfer between PDA and iridium polymer in the active layer (PDA-PPy3Ir) under an applied voltage.Keywords:memory device;mussel chemistry;surface modification;SI-ATRP

We systematically investigated the development of film morphology and crystallinity of methyl-ammonium bismuth (III) iodide (MA 3 Bi 2 I 9 ) through onestep spin-coating on TiO 2 -deposited indium tin oxide (ITO)/glass. The precursor solution concentration and substrate structure have been demonstrated to be critically important in the active-layer evolution of the MA 3 Bi 2 I 9 -based solar cell. This work successfully improved the cell efficiency to 0.42% (average: 0.38%) with the mesoscopic architecture of ITO/compact-TiO 2 /mesoscopic-TiO 2 (meso-TiO 2 )/MA 3 Bi 2 I 9 /2,2′,7,7′-tetrakis(N,N-di-4-methoxyphenylamino)-9,9′spiro-bifluorene (spiro-MeOTAD)/MoO 3 /Ag under a precursor concentration of 0.45 M, which provided the probability of further improving the efficiency of the Bi 3+ -based lead-free organic–inorganic hybrid solar cells.

Solar water splitting as a promising way to convert solar energy into hydrogen energy has been largely limited by the low efficiency of photoanodes in photoelectrochemical water oxidation. In this work, through deliberately employing a indium tin oxide (ITO) underlayer as an electron transport layer (ETL) and a Fe 2 TiO 5 overlayer as a hole transport layer (HTL), a novel triple-layer ITO/BiVO 4 /Fe 2 TiO 5 heterojunction photoanode was prepared by solution-processed sequential deposition. Owing to the unique ETL/BiVO 4 /HTL heterojunction structure, the photocurrent density at 1.23 V RHE was significantly increased from 1.70 mA/cm 2 for the pristine BiVO 4 photoanode to 4.60 mA/cm 2 for the ITO/BiVO 4 /Fe 2 TiO 5 photoanode. After iron silicate (Fe-Sil) was deposited as a new and efficient cocatalyst, the resultant quaternary ITO/BiVO 4 /Fe 2 TiO 5 /Fe-Sil photoanode achieved an extremely high photocurrent density of 6.19 mA/cm 2 and an ABPE value as high as 2.55%, indicating an outstanding performance toward solar water oxidation. The high performance of the quaternary ITO/BiVO 4 /Fe 2 TiO 5 /Fe-Sil photoanode may be attributed to the desired ETL/BiVO 4 /HTL heterojunction structure in combination with the utilization of the Fe-Sil as an efficient oxygen evolution cocatalyst.

Fabrication of large-area devices with patternable nanostructures is important for practical applications in optical or electrical devices. In this work, we describe an easy and environment-friendly method for preparing large-area nano-dot (ND) arrays via the electrolytic reaction of a metal oxide film. NDs with various size and morphology can be obtained by adjusting the applied voltage, electrolysis time, and the film thickness of the indium tin oxide (ITO) layer. High-density NDs with size of 50–60 nm can be obtained by electrolysis of a 25-nm-thick ITO film at 150 V for 1.5 min under a water droplet medium, which have been applied for surface-enhanced Raman spectroscopy (SERS) after depositing a thin layer of silver. The SERS substrate with optimized ND structure exhibits sensitive detection of Rhodamine 6G (R6G) with detection limit down to 5 × 10 -12 M. The enhancement factors (EFs) of 1.12 × 10 6 and 6.79 × 10 5 have been achieved for characterization of 4-methylbenzenethiol (4-MBT) and R6G, respectively. With an additional photolithographic step, multiple areas of ND arrays can be created on one substrate, enabling simultaneous detection of various samples containing different molecules at once experiment. Such a method is quick, easy, patternable, and environment-friendly, being suitable for on-site quick and synchronous determination of various molecules for applications in point-of-care, environmental monitoring, and airport security fields.

A facile and highly sensitive determination of prostate-specific antigen (PSA) is of great significance for the early diagnosis, monitoring and prognosis of prostate cancer. In this work, a disposable and label-free electrochemical immunosensing platform was demonstrated based on chitosan–graphene-modified indium tin oxide (ITO) electrode, which enables sensitive amperometric determination of PSA. Chitosan (CS) modified reduced graphene oxide (rGO) nanocomposite (CS–rGO) was easily synthesized by the chemical reduction of graphene oxide (GO) using CS as a dispersant and biofunctionalizing agent. When CS–rGO was modified on the patterned ITO, CS offered high biocompatibility and reactive groups for the immobilization of recognition antibodies and rGO acted as a transduction element and enhancer to improve the electronic conductivity and stability of the CS–rGO composite film. The affinity-based biosensing interface was constructed by covalent immobilization of a specific polyclonal anti-PSA antibody (Ab) on the amino-enriched electrode surface via a facile glutaraldehyde (GA) cross-linking method, which was followed by the use of bovine serum albumin to block the non-specific sites. The immunosensor allowed the detection of PSA in a wide range from 1 to 5 ng mL−1with a low limit of detection of 0.8 pg mL−1. This sensor also exhibited high selectivity, reproducibility, and good storage stability. The application of the prepared immunosensor was successfully validated by measuring PSA in spiked human serum samples.Keywords:amperometric immunosensor;graphene composite;chitosan;disposable electrode;prostate-specific antigen

Semitransparent organic photovoltaics (ST-OPVs), owing to the merits of high power generation, thermal insulation, and aesthetic features, have become a promising candidate for intellectual building- integrated photovoltaic windows. However, the traditional optical evaluation only focuses on the transmission properties and ignores the reflection behaviors. And the lack of quantitative descriptions for array appearance hinders implementation of ST-OPV based large-area modules. To tackle with these issues, an indium tin oxide (ITO)-free optical microcavity architecture into ST-OPVs for achieving high homogeneity in transmittance with controllable reflective appearances through tunning the thickness of individual component layers is introduced. A set of parameters based on optical characteristics of sub-units to provide a quantitative description for the transmittance brightness, transmissive and reflective color purity, and versatility of optical arrays, is further proposed. The optical simulations reveal that reflection modulation from blue to red colors can be realized for devices based on various bulk-heterojunction material systems through regulating the thickness of active layers and antireflection coatings. This work offers a viable design strategy for ST-OPVs toward applications in next-generation smart photovoltaic windows.

An efficient method has been developed for visualizing latent fingerprints by spatially selective electropolymerization of luminol on the ITO electrode. The fingerprint deposited on the electrode surface functions as a mask so that polyluminol is formed on the bare electrode surface. Therefore, electrochemiluminescence is only generated between the ridges of fingerprint, eventually yielding a negative ECL image. This method is easy to operate and safe to examiners. In addition, the second- and third-level details of fingerprints can be well resolved, indicating the potential application for personal identification and forensic investigation.

Barium titanate (BaTiO 3 , BT) is an excellent electronic material with great application for multilayer ceramic capacitors (MLCCs). In this work, BaTiO 3 based- In 2 O 3 ·SnO 2 (ITO) composite ceramics were synthesized via solid-state reaction method, which optimizes the dielectric properties of the BT-based materials through the atomic scale to the micro-nano scale. The BaTiO 3 based material is composited with ITO to construct the percolation capacitor, which greatly enhances the room-temperature dielectric constant of BT-based materials. Among them, the grain sizes of BT-based material and ITO are 552–581 nm and 483–553 nm, respectively. In addition, BT-based materials are obtained after optimization of the rare earth ion doping effect and the “core-shell” effect. The substitutional defects generated by the rare earth Gd 3+ ions produce abundant positive and negative charges in the core phase BT, which also leads to the optimization of the room-temperature permittivity. Meanwhile, the “core-shell” structure produced by niobate-encapsulated BT-based material with doped Gd 3+ ions further enhances the dielectric-temperature stability of BT-based materials. Based on the synergy of rare earth ion doping effect, “core-shell” effect, and percolation effect, Ba 0.9985 Gd 0.0015 @(Ni,Mn)Nb 2 O 6 -ITO (BGT@(N,M)NO-ITO) percolation composite ceramics have a room temperature dielectric constant as high as 7184 with a dielectric low loss of 3.8 %, and the temperature stability meets X8R. In this work, the BGT@(N,M)NO-ITO percolation composite ceramics with excellent dielectric properties are expected to be used in MLCCs, which further broadens the application of BT-based materials.

In this work, a sensitive and reliable photoelectrochemical (PEC) sensor array integrated on a single electrode was developed for the spatially addressable detection of neuron-specific enolase (NSE), using Bi 2 O 3 /Bi 2 S 3 /Ag 2 S nanodendrites as the substrate electrode material. The Bi 2 O 3 /Bi 2 S 3 structure was grown in situ on an indium tin oxide (ITO) electrode to form large-area nanoarrays, whose uniform distribution helps minimize performance variations across different regions and enables light-addressable detection. Furthermore, Ag 2 S, a narrow-bandgap semiconductor with excellent photoelectric properties, was incorporated into the Bi 2 O 3 /Bi 2 S 3 system to enhance the photoelectrochemical response. The resulting Bi 2 O 3 /Bi 2 S 3 /Ag 2 S-modified ITO electrode was partitioned into five independent regions using insulating stickers, allowing addressable and continuous detection of multiple samples. Since the entire sensor array was fabricated in a single preparation step, inter-regional variability was significantly reduced, enabling the application of a self-calibration strategy to further improve sensitivity and accuracy. Under optimal conditions, the PEC sensor array detected NSE over a concentration range of 0.01–100 ng/mL, with a detection limit of 2.0 pg/mL (S/N = 3). The sensor also exhibited high selectivity, stability, and reproducibility, demonstrating its strong potential for real-sample applications.
