“…Homojunction Cu 2 O solar cell had an efficiency of 1.06% because of the high resistivity of p-/n-bilayers [158]. In addition, surface sulphidation of electrodeposited n-Cu 2 O and the p-Cu 2 O film was found to be useful for improvement in the film photoactivity [159]. It was found out that on the efficiency of homojunction Cu 2 O solar cell grain size and crystal orientation had a significant role because of changing the resistivity of the p-type Cu 2 O [160].…”

Considering metal oxide nanoparticles as important technological materials, authors provide a comprehensive review of researches on metal oxide nanoparticles, their synthetic strategies, and techniques, nanoscale physicochemical properties, defining specific industrial applications in the various fields of applied nanotechnology. This work expansively reviews the recent developments of semiconducting metal oxide gas sensors for environmental gases including CO 2 , O 2 , O 3 , and NH 3 ; highly toxic gases including CO, H 2 S, and NO 2 ; combustible gases such as CH 4 , H 2 , and liquefied petroleum gas; and volatile organic compounds gases. The gas sensing properties of different metal oxides nanoparticles towards specific target gases have been individually discussed. Promising metal oxide nanoparticles for sensitive and selective detection of each gas have been identified. This review also categorizes metal oxides sensors by analyte gas and also summarizes the major techniques and synthesis strategies used in nanotechnology. Additionally, strategies, sensing mechanisms and related applications of semiconducting metal oxide materials are also discussed in detail. Related applications are innumerable trace to ultratrace-level gas sensors, batteries, magnetic storage media, various types of solar cells, metal oxide nanoparticles applications in catalysis, energy conversion, and antennas (including microstrip and patch-type optically transparent antennas), rectifiers, optoelectronic, and electronics.

“…In this article, n‐Cu 2 O thin films were electrodeposited potentiostatically on well‐cleaned titanium (Ti) substrates using an aqueous bath solution containing 0.1 m sodium acetate and 0.01 m cupric acetate solutions. [ 24–26 ] For the electrodeposition, a three‐electrode electrochemical cell containing a Ti substrate as the working electrode, a platinum plate as the counter electrode, and a Ag/AgCl electrode as the reference electrode was used. Films were deposited at a deposition potential of −200 mV versus Ag/AgCl, a bath temperature of 55 °C, and a deposition duration of 60 min.…”

A surface modification technique is developed for electrodeposited n‐cuprous oxide (Cu2O) thin film electrodes to enhance water splitting in a photoelectrochemical (PEC) cell. For this, Cu2O films are modified using ammonium sulfide vapor with a unique exposure condition to produce ultrathin sulfided surface layers. To ascertain the effect of surface modification, films are investigated in a PEC cell containing 0.1 m sodium acetate aqueous electrolyte using current–voltage, spectral response, and capacitance–voltage measurements. It is revealed that as a result of the surface modification, high photocurrents are produced by the surface‐modified electrodes. Also, it is revealed that the Fermi level pinning presents at the Cu2O/electrolyte interface can be removed and the flat band potential can be shifted negatively by the surface modification. The experimental evidences support the idea that the surface modification can change the surface states present at the n‐Cu2O/electrolyte interface. The enhancement of photocurrent may be attributed to the increase in depletion layer thickness and reduction of surface recombination of photogenerated charge carriers. The surface modification technique developed in this study for n‐Cu2O films enables to produce an enhanced solar‐to‐hydrogen conversion efficiency of 1.47% at the bias potential of 0.553 V versus reversible hydrogen electrode.
