“…42 In addition, film thickness, morphology, and optical and electronic properties can be controlled by various deposition parameters, such as current density, applied potential, deposition time, and electrolytic bath concentration. [51][52][53] Photovoltaic devices with p-type Cu 2 O films have been prepared with n-type ZnO in a heterojunction configuration. However, for Cu 2 O devices configured with pn junction, γ-WO 3 (tungsten trioxide) seems to be an adequate material since it presents optical band gap energy (E BG ) ranging from 2.6 to 2.8 eV, which allows the harvesting of visible light, 54 while ZnO absorbs in UV light.…”

Summary In this article, we report a solar cell prepared with p‐type cuprous oxide (Cu2O) and n‐type gamma‐tungsten oxide (γ‐WO3) films combined by an redox electrolyte in a configuration similar to that used in dye‐sensitized solar cells. Cu2O films were prepared by the electrochemical method in three different pH conditions. X‐ray diffraction patterns revealed that the Cu2O films presented a crystalline phase with cubic structure after deposition, whereas the n‐type γ‐WO3 film was prepared by the drop‐casting method. Optical analyses showed that both oxide films absorb visible light. After the photoelectrochemical characterization of the films, solar cells configured like a “sandwich” (Cu2O/electrolyte/γ‐WO3) were assembled and investigated under irradiation of 100 mW cm−2. The solar cell with I−/I3− redox pair showed better results than that prepared with polysulfide K2S/Sn2− electrolyte. For each solar cell, the investigated parameters were short‐circuit current density, open‐circuit voltage, fill factor, maximum power, and cell efficiency. The method proposed here can be considered new, promising, and simple for the preparation of solar cells with a p–n junction.

The Bi2O3 thin films were prepared onto glass substrates by spray pyrolysis method. The Bi2O3 thin films optimized at 320 °C spray pyrolysis temperature. The crystal structure, crystallite size, and surface morphology of Bi2O3 thin films were studied by X‐ray diffraction (XRD) and scanning electron microscopy (SEM) techniques, respectively. The X‐ray diffraction pattern of Bi2O3 thin films show polycrystalline in nature. The SEM images show porous morphology of Bi2O3 thin films. The optical absorption spectra of films were examined in order to study their band gap energy. The optical study shows a direct band gap of 2.90 eV for Bi2O3 films.

The copper oxide (CuO) based films have been prepared for biosensing application. Electrodeposition mode has been used for preparation of CuO films on cost effective stainless steel substrates. The structural properties of CuO material are studied by X‐ray diffraction (XRD) pattern and it shows (ī11) more intensive plane. Hierarchical multilayer nanosheets clusters have been displayed in scanning electron microscopic images. The energy dispersive X‐ray analysis (EDAX) pattern displays wt% of Cu and oxygen in CuO material and it is found to be 52.80% and 57.61%. The glucose sensing of CuO electrodes is carried out in NaOH and glucose electrolyte at different concentration of glucose and 10–50 mV s−1 scan rates. The effect of glucose sensing on CuO electrode has been studied.
