“…Gas chromatography was used to assess the rate of hydrogen creation, and the catalyst performed better with rotation during the OER and HER. These findings demonstrate the potential of CuYO 2 nanopowder as a viable catalytic material for hydrogen generation applications, including fuel cells, battery devices, electrolysers, and solar water splitting [102,[132][133][134].…”

“…CuCrO 2 , on the other hand, stands out as an attractive option for photocatalytic applications due to its outstanding chemical stability, p-type semiconductor characteristics, and ability to absorb visible light. Previous research has demonstrated its capacity to create hydrogen from water and remove metal ions when exposed to visible light [102]. Notably, Mgdoped CuCrO 2 has demonstrated improved photocatalytic hydrogen generation activity.…”

This review paper reports on the use of Delafossite as a layer between perovskite-based solar cells to improve hydrogen production efficiency and make the process easier. The investigation delves into the possible breakthroughs in sustainable energy generation by investigating the synergistic interplay between Delafossite and solar technology. This investigation covers copper-based Delafossite material’s properties, influence on cell performance, and function in the electrolysis process for hydrogen production. Some reports investigate the synthesis and characterizations of delafossite materials and try to improve their performance using photo electrochemistry. This work sheds light on the exciting prospects of Delafossite integration using experimental and analytical methodologies.

“…For this purpose, the atomic positions were optimized, and the electronic properties were computed within the Density Functional Theory (DFT) approach. This was conducted based on the framework of the generalized Kohn–Sham scheme [ 99 , 100 , 101 ] in combination with the projector augmented-wave (PAW) method [ 102 ] and the Heyd–Scuseria–Ernzerhof hybrid functional with the modified fraction of screened short-range Hartree–Fock exchange (HSE06) [ 103 , 104 , 105 ] as implemented in the Vienna ab initio simulation package (VASP) [ 106 , 107 , 108 , 109 , 110 ]. Hybrid functionals allow for a more accurate description of electronic properties of some systems compared to simple DFT calculations with a generalized gradient approximation for the exchange and correlation term in the Kohn–Sham scheme.…”

A novel manufacturing process is presented for producing nanopowders and thin films of CuCoO2 (CCO) material. This process utilizes three cost-effective synthesis methods: hydrothermal, sol-gel, and solid-state reactions. The resulting delafossite CuCoO2 samples were deposited onto transparent substrates through spray pyrolysis, forming innovative thin films with a nanocrystal powder structure. Prior to the transformation into thin films, CuCoO2 powder was first produced using a low-cost approach. The precursors for both powders and thin films were deposited onto glass surfaces using a spray pyrolysis process, and their characteristics were examined through X-ray diffraction, scanning electron microscopy, HR-TEM, UV-visible spectrophotometry, and electrochemical impedance spectroscopy (EIS) analyses were conducted to determine the conductivity in the transversal direction of this groundbreaking material for solar cell applications. On the other hand, the sheet resistance of the samples was investigated using the four-probe method to obtain the sheet resistivity and then calculate the in-plane conductivity of the samples. We also investigated the aging characteristics of different precursors with varying durations. The functional properties of CuCoO2 samples were explored by studying chelating agent and precursor solution aging periods using Density Functional Theory calculations (DFT). A complementary Density Functional Theory study was also performed in order to evaluate the electronic structure of this compound. Resuming, this study thoroughly discusses the synthesis of delafossite powders and their conversion into thin films, which hold potential as hole transport layers in transparent optoelectronic devices.

Photovoltaic perovskites are very attractive candidates as absorber layers because of their very interesting properties. In the present work, we have two parts: first, we prepared powders of the perovskites MAPbBr3, MAPbI3, and MAPbCl3, with the aim of maximizing their purity, and then we deposited thin films using these powders previously prepared by the one-step spin-coating method. The anti-solvent used was under the same ambient deposition conditions. We concluded with a series of characterizations such as X-ray diffraction, scanning electron microscopy, and UV–visible absorption to better appreciate the quality of the films produced. The crystalline structures of the films, their surface morphology, and their optical properties from the characterizations show that we have succeeded in producing film samples suitable for photovoltaics.
