Fluorine-doped tin oxide (FTO) films were prepared by pulsed DC magnetron sputtering with a metal Sn target. Two different modes were applied to deposit the FTO films, and their respective optical and electrical properties were evaluated. In the transition mode, the minimum resistivity of the FTO film was 1.63×10(-3) Ω cm with average transmittance of 80.0% in the visible region. Furthermore, FTO films deposited in the oxide mode and mixed simultaneously with H2 could achieve even lower resistivity to 8.42×10(-4) Ω cm and higher average transmittance up to 81.1% in the visible region.

In this study, TiO-P25 films on FTO substrates were synthesized using the sol-gel process and studied using Variable Angle Spectroscopy Ellipsometry (VASE) to determine their optical constants and thickness. The measurements were carried out at room temperature in the wavelength range of (300-900) nm at incident angles varying from 55° to 70°. The resulting thicknesses were found to be around 1000 nm.

Hydrogen-substituted graphdiyne (HsGDY) is a two-dimensional material with an sp-sp carbon skeleton featuring a band gap and a porous structure that enhances ion diffusion. In previous reports, HsGDY growth was limited to metal substrates such as Cu, which then required transfer. Here, we developed a sandwich method that allows HsGDY to be grown directly on the target substrate.

The utilization of single crystals is exponentially growing in optoelectronic devices due to their exceptional benefits, including high phase purity and the absence of grain boundaries. However, achieving single crystals with a porous structure poses significant challenges. In this study, we present a method for fabricating porous single crystals (porous-SC) of CsAgBiBr and related halide double perovskites using an infrared-assisted spin coating technique.

Rationalizing the role of chemical interactions in the precursor solutions on the structure, morphology, and performance of thin-film CuZnSn(S,Se) (CZTSSe) is key for the development of bifacial and other photovoltaic (PV) device architectures designed by scalable solution-based methods. In this study, we uncover the impact of dimethylformamide (DMF) and isopropanol (IPA) solvent mixtures on cation complexation and rheology of the precursor solution, as well as the corresponding morphology, composition, and PV performance of CZTSSe thin-film grown on fluorine-doped tin oxide (FTO). We find that increasing the proportion of IPA leads to a nonlinear increase in dynamic viscosity due to the strong repulsion between DMF and IPA, which is characterized by an interaction cohesion parameter of 3.

Cuprous oxide (CuO) as an intrinsic p-type semiconductor is promising for solar energy conversion. The major challenge in fabricating CuO lies in achieving both high transparency and high performance in a tandem device. The CuO photocathodes often employ gold as the back contact layer.
