“…The TC sample based on an Ag layer 9.0 nm thick was also annealed at 200, 300, and 400 • C for 30 min, and the results are shown in Figure 5c,d. There was little change in the transmittance spectra of the sample after annealing at 200 and 300 • C, but a dramatic drop for the sample annealed at 400 • C, demonstrating the high-temperature application potential up to 300 • C. The sheet resistance of the sample decreased with an annealing temperature up to 300 • C. Nevertheless, after heat treatment at 400 • C for 30 min, the sheet resistance of the sample showed an obvious increase from 5.9 to 25.7 Ω.sq −1 , which may be due to the oxidation of and damage to the continuity of the Ag layer caused by the TiO 2 layer's crystallization [13,43,44]. To verify the flexibility, the samples, on polymetric PET substrate, were subjected to a bending test using a homemade one-dimensional motorized translation stage.…”

Transparent conductors (TC) have been widely applied in a wide range of optoelectronic devices. Nevertheless, different transparent spectral bands are always needed for particular applications. In this work, indium tin oxide (ITO)-free TCs with tunable transparent bands based on the film structure of TiO2/Ag/AZO (Al-doped ZnO) were designed by the transfer matrix method and deposited by magnetron sputtering. The transparent spectra and figure-of-merit (FOM) were effectively adjusted by precisely controlling the Ag layer’s thickness. The fabricated as-deposited samples exhibited an average optical transmittance larger than 88.3% (400–700 nm), a sheet resistance lower than 7.7 Ω.sq−1, a low surface roughness of about 1.4 nm, and mechanical stability upon 1000 bending cycles. Moreover, the samples were able to hold optical and electrical properties after annealing at 300 °C for 60 min, but failed at 400 °C even for 30 min.

Thermal, electrical, and chemical instabilities affect the efficient integration of silver nanowire (AgNW) networks as transparent electrodes for energy and wearable electronics. By coupling experimental data and a simple physical model, we deduce the electrical areal power density ranges that AgNW networks can withstand, to observe either reversible modifications (i.e., electron− phonon interaction) or irreversible modifications (i.e., electrical sintering or degradation). This approach also allows us to predict the associated Joule heating temperature in the reversible domain for any applied voltage and initial resistance. It constitutes an efficient guide to design any device incorporating AgNW networks in which electrical current is applied. To improve AgNW stability, tin oxide (SnO 2 ) coating has been deposited by atmospheric-pressure spatial atomic layer deposition at 200 °C. For a similar initial resistance, the observed maximum areal power density increases from 1.6 to 3.3 W cm −2 for bare AgNWs and 40 nm-SnO 2 /AgNW networks, respectively, and their associated Joule heating temperatures are 220 and 410 °C, respectively. In addition to the high electrical stability of SnO 2 /AgNW nanocomposites, we demonstrate their enhanced stability when exposed to either thermal stress up to 400 °C, or environmental stress with 80% of relative humidity at 70 °C for 2 weeks.

“…Additionally, SnO 2 /BiVO 4 /rGO construction yielded a photocurrent of 2.05 mA/cm 2 at 1.23 V RHE , (about four times of the BiVO 4 alone) and IPCE of ~2.5 times that of BiVO 4 at 400 nm [ 15 ]. Wang et al [ 16 ] fabricated SnO 2 /Ag/SnO 2 tri-layers on float substrate by magnetron sputtering. The film showed a sheet resistance of 5.92 Ω/sq and transmittance of 87.0% which is useful for use in CdTe solar cells.…”

Obtaining H2 energy from H2O using the most abundant solar radiation is an outstanding approach to zero pollution. This work focuses on studying the effect of Co doping and calcination on the structure, morphology, and optical properties of spin-coated SnO2 films as well as their photoelectrochemical (PEC) efficiency. The structures and morphologies of the films were investigated by XRD, AFM, and Raman spectra. The results confirmed the preparation of SnO2 of the rutile phase, with crystallite sizes in the range of 18.4–29.2 nm. AFM showed the granular structure and smooth surfaces having limited roughness. UV-Vis spectroscopy showed that the absorption spectra depend on the calcination temperature and the Co content, and the films have optical bandgap (Eg) in the range of 3.67–3.93 eV. The prepared samples were applied for the PEC hydrogen generation after optimizing the sample doping ratio, using electrolyte (HCl, Na2SO4, NaOH), electrode reusability, applied temperature, and monochromatic illumination. Additionally, the electrode stability, thermodynamic parameters, conversion efficiency, number of hydrogen moles, and PEC impedance were evaluated and discussed, while the SnO2 films were used as working electrodes and platinum sheet as an auxiliary or counter electrode (2-electrode system) and both were dipped in the electrolyte. The highest photocurrent (21.25 mA/cm2), number of hydrogen moles (20.4 mmol/h.cm2), incident photon-to-current change efficiency (6.892%@307 nm and +1 V), and the absorbed photon-to-current conversion efficiency (4.61% at ~500 nm and +1 V) were recorded for the 2.5% Co-doped SnO2 photoanode that annealed at 673 K.
