Summary: Chemical bath methods for growing thin film semiconductors produce a lot of waste solvent and chemicals. This study successfully replaced the toxic chemical bath deposited CdS buffer layer with a benign inkjet-printed and annealed Zn(O,S) layer, greatly reducing solvent and chemical usage. The wetting and final performance of the Zn(O,S) layer on CIGS can be controlled by various factors, with the best device efficiency reaching 13.5% through optimization.

Summary: Hydrothermal deposition is considered a promising method for antimony-based solar cells, with TiO2 evaluated as a potential Cd-free buffer layer, and Zn(O,S) effectively addressing the issue of inhomogeneous Sb2S3 coverage. The Zn(O,S)/Sb2S3 junction exhibits more stable structure and enhances the efficiency of the device compared to TiO2/Sb2S3.

Summary: This paper reports the band alignment dependence of the CZTSSe/Zn(O,S) interface with different oxygen concentrations, which allows high controllability of the energy levels of the buffer layers and leads to higher solar cell efficiencies. The study also demonstrates a novel process, high vapor transport deposition, for depositing Zn(O,S) thin-film layers.

Summary: This study effectively suppressed the light soaking effect in Zn(O,S)/CIGS solar cells by carefully regulating the surface components of the submicron CIGS absorption layer. It increased the conversion efficiency of the solar cells, especially the fill factor. By combining appropriate surface regulation and an anti-reflection layer of MgF2, a 17.6% Cd-free submicron CIGS solar cell with significantly lower light soaking effect was achieved, representing the highest value in submicron CIGS solar devices. This research paves the way for suppressing the metastable effect in CIGS absorber layer.

Summary: Copper indium gallium sulfur (CIGS) solar cells exhibit good efficiency, but the efficiency is greatly influenced by the buffer/absorber and absorber/back contact interfaces. This study investigates CIGS-based solar cells using two different buffer layers, ZnO1-xSx and SnS2, as non-toxic alternatives to CdS. Results show that a ZnO1-xSx buffer layer with a sulfur composition ratio of 0.85 leads to improved performance of CIGS solar cells up to 23.94%. Additionally, the use of SnS2 as a buffer layer slightly affects the efficiency and results in an efficiency of 23.44%.

Summary: The room temperature growth of zinc-doped iron oxide films (Zn:FeOx) on different sapphire substrates was investigated using the pulsed-laser deposition method. Characterization techniques including Rutherford backscattering spectrometry, X-ray diffraction analysis, pole figure measurements, and transmission electron microscopy were employed to determine the nature of the oxide phases, their texture, and the in-plane epitaxial relationships. The results showed variations in oxide phases and textures on different sapphire substrates.

Summary: We developed a novel process for fabricating oxygen-rich Zn(O,S) buffer layers suitable for industrial production. By precisely controlling the composition of Zn(O,S), we investigated its effects on film quality, p-n junction properties, and CIGSSe solar cell performance. We observed that the appropriate content of ZnSO4 and ZnSO3 secondary phases improved the band alignment of oxygen-rich Zn(O,S). By establishing a crucial correlation between device performance and interfacial properties, we found that the band alignment matching at the heterojunction plays a primary role in CIGSSe device performance. An excellent oxygen-rich Zn(O,S) buffer can be obtained with 10% Zn(O,S) deposition oxygen partial pressure.

Summary: The chemical and electronic structure of the interface between a sputter-deposited Zn(O,S) buffer layer and an industrial Cu(In,Ga)(S,Se)(2) (CIGSSe) absorber for thin-film solar cells was investigated using various spectroscopic techniques. It was found that the CIGSSe absorber surface band gap significantly increased compared to bulk-sensitive methods. The measurements also showed the presence of S-Zn and S-O bonds in the Zn(O,S) layer, and an enhanced carrier separation at the interface.

Summary: Aluminum-doped indium zinc magnesium oxide films with a tunable conduction band structure were developed via room temperature deposition. These films exhibit high Hall mobility and low carrier density due to the introduction of a small amount of aluminum oxide. Furthermore, the addition of magnesium oxide allows for the control of the optical bandgap while maintaining a constant ionization energy.

Summary: Selective methane photocatalytic oxidation to CO and H2 at ambient conditions is a main challenge in the chemical industry. In this study, conventional Cu (In,Ga)Se2 (CIGS) absorbers used in solar cells were found to be excellent candidates for methane valorization. A thin film of CIGS coated over Mo demonstrated exceptional performance in methane partial oxidation to CO and H2, with a stable CO productivity of 2.4 mmol per gram of CIGS and a selectivity to CO of over 80%.
