“…It is known that the optical, electrical, and structural properties of metal oxides are affected by different doping. In their studies, Xu et al [25] found that Mn doping caused modifications to the structural and magnetic properties of CuO. In another study, Bayansal et al [26] stated that when Co doping increased, the crystallite size of the CuO films decreased.…”

In the present work, structural, optical, and electrical properties of lithium-doped (0-6 at.%) copper oxide thin films were investigated. The films were obtained by the spray pyrolysis method on glass substrates at 450 • C. The X-ray diffraction method, UV-visible spectroscopy, and the four-point probe technique were used to analyze the films. Based on the X-ray diffraction investigations, it was found that the polycrystalline films have monoclinic phases with preferred (111) and ( 111) crystallographic planes. The incorporation of lithium doping into the copper oxide thin film yielded crystallite sizes of approximately 2 nm. The estimated optical band gap values are decreased from 1.88 to 1.64 eV with increasing lithium concentration. Four-point probe studies revealed that the resistivity of the films decreased from 339 to 186 K Ω cm with increasing lithium concentration.

“…Besides this, numbers of transition metals have been used as dopants to alter the physical and chemical properties of CuO nanostructures. In fact, the transition metal ions dopant create an impurity level between the conduction and valence band which act as an intermediate step to support the electron during excitation upon photon absorption [14][15][16][17][18]. These impurity levels can consider as an acceptor levels, deep recombination centers and shallow donor [19,20].…”

Herein, transition metals i.e. Mn, Fe doped CuO nanostructures were synthesized via simple and facile wet chemical method. As-prepared materials were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), transmission electron microscope (TEM), ultraviolet-visible and emission spectroscopy. The XRD studies reveal that doped and un-doped CuO have single phase, suggesting the incorporation of Mn and Fe dopants in CuO lattice. Further, as-synthesized materials were used in the hybrid bulk heterojunction organic solar cell and it was found that the low concentration of doping increase the charge separation led to enhance the power conversion efficiency of the device as compared to high amount of doping. This increase in the power conversion efficiency of the prepared devices is mostly due to increase in fill factor and short-circuit current density upon doping of Mn:Fe to CuO nanostructures.

“…Many authors have reported the changes associated with doping of transition metal ions into CuO lattice, which have been observed experimentally in Mn [14,15], Ni-doped CuO [16], Fe and Ni co-doped [17], Ti, Cd and Zn [18]. Very few reports are available on Zn doped CuO nanoparticles.…”
